[DataModeling] Tip DAX para autoreferencia o recurrencia de tabla

Hace tiempo que no nos sentrabamos en acompañar un escenario de modelado. En esta oportunidad, nos vamos a enfocar en como resolver una situación de auto referencia o recurrencia de tabla. Suele ocurrir que una tabla puede tener ids o claves de referencia para si misma y las formas de resolverlo pueden variar.

En este artículo, vamos a mostrar como valernos de DAX para resolver un esquema jerárquico corporativo que ayude a develar un organigrama organizacional basado en niveles o posiciones/cargos superiores.

Contexto

Entre las formas de modelar bases de datos transaccionales, buscamos normalizar los datos para evitar la redundancia lo más posible. Así es como pueden aparecer escenarios donde hay tablas que van a referenciarse a si mismas. Esto quiere decir que podemos tener una clave foránea apuntando a una clave primaria. Para no abordar tanta teoría veamos un ejemplo que ayude a enfocar el caso.

Nos enviaron un requerimiento que pide detallar un organigrama o estructura jerárquica en la organización que permita explorar la cantidad de empleados según distintos focos de mando. Piden que la información sea explorable, puede ser una matriz o árbol del siguiente estilo:

Árbol de decomposición

Matriz

Supongamos que tenemos una tabla de Empleados en nuestra base de datos. La organización tiene un gran volumen de personal, lo que hace que naturalmente haya una estructura jerárquica con cargos de mando o de management. Todas las personas institucionales forman parte de la tabla empleados fila por fila. Sin embargo, necesitamos guardar información sobre la persona a la cual responden. Aquí aparece la auto referencia. Para resolver esta operación en vistas de base de datos transaccional, será más performante y menos costoso delimitar una nueva columna que autoreferencie a otra fila en lugar de otras tablas para los cargos pertinentes. Veamos como quedaría una tabla con la nueva columna:

Fíjense que la columna id_superior pertenece a un id_empleado de otra fila. Cuando esto ocurre, estamos frente a un caso de auto referencia.

Dependiendo el proceso y escenario a delimtiar en nuestro modelo semántico, puede ser resuelto de distintas formas. Podríamos generar fact factless que orienten un mapeo de quienes responden a quienes o podemos tomar esta tabla como dimensión y generar columnas que representen el mando jerárquico como columnas categóricas de la dimension.

Este artículo se enfocará en la segunda solución. Vamos a generar columnas categoricas que nos ayuden a construir algo semejante a lo siguiente:

La idea es generar columns por cantidad de niveles jerárquicos que se presenten. Si bien la mejor solución es implementarlo lo más temprano posible, es decir en un warehouse, lakehouse o procesamiento intermedio; aquí vamos a mostrar como crear las columnas con DAX.

Vamos a crear una columna calculada de la siguiente manera:

Level1 = LOOKUPVALUE( Empleados_Jerarquia[Nombre] , Empleados_Jerarquia[id_empleado] , PATHITEM( PATH ( Empleados_Jerarquia[id_empleado], Empleados_Jerarquia[id_superior]) , 1 , INTEGER ) )

Vamos a nutrirnos de tres funciones para generar un recorrido dentro de la misma tabla.

LOOKUPVALUE: Esta función busca un valor en una columna específica de una tabla, basándose en criterios de búsqueda. En este caso, está buscando el nombre de un empleado con criterio de igualdad entre id_empleado que mapee al id_superior de la fila actual.

PATH: Esta función crea una cadena que representa la jerarquía de empleados, utilizando los id_empleado y id_superior. Busca los ID y los separa por Pipes. Entonces por ejemplo en la fila de ID = 5 de Joaquín. El resultado de Path será "1|2|5" representando que los ID de sus superiores son primero el empleado 2 y luego el empleado 1.

PATHITEM(..., 1, INTEGER): Esta función toma la cadena generada por PATH y extrae un elemento de ella. En este caso, está extrayendo el primer elemento (el id del empleado que está en la posición 1). Aquí, el 1 se refiere a la posición que queremos extraer (el primer ítem en la jerarquía). Si Joaquín tenía 3 valores, vamos a buscar el de la primera posición, en este caso "1".

Resultado: lookupvalue buscara el nombre del empleado con ID 1 para la columna.

Esta función podríamos replicarla para cada nivel. La función antes vista traería el primero de la cadena, es decir la dirección de la empresa. Para llegar al siguiente nivel cambiamos el parametro de pathitem de manera que traiga el segundo resultado de Path en sus pipes.

Level2 = LOOKUPVALUE( Empleados_Jerarquia[Nombre] , Empleados_Jerarquia[id_empleado] , PATHITEM( PATH ( Empleados_Jerarquia[id_empleado], Empleados_Jerarquia[id_superior]) , 2 , INTEGER ) )

En primera instancia esto parecería resolverlo. Este sería nuestro resultado:

Esta puede ser una solución directa si solo queremos navegar por nombres de personas en cadena (filtramos Level5 <> Blank). Sin embargo, si también quisieramos conocer la cantidad de personas que tienen a cargo, es necesario contar a la persona al mando como parte del equipo, sino generaríamos una cadena de "Blanks" como pueden ver en niveles del 2 al 5. Esto lo podemos corregir copiando el nivel anterior cuando ocurre un blanco.

Level2 = VAR __lvl2 = LOOKUPVALUE( Empleados_Jerarquia[Nombre] , Empleados_Jerarquia[id_empleado] , PATHITEM( PATH ( Empleados_Jerarquia[id_empleado], Empleados_Jerarquia[id_superior]) , 2 , INTEGER ) ) RETURN IF ( ISBLANK(__lvl2) , Empleados_Jerarquia[Level1], __lvl2 )

De esa forma el equipo de Laura (primera) cuenta con tres gerentes y si misma al conteo total de empleados.

Las visualizaciones pueden ser construidas por cada nivel como columnas categóricas de las dimensiones:

Así mismo podría usarse el nombre del cargo como nombre de columna para ver la pirámide institucional de una manera más sencilla.

De esta forma llegaríamos al resultado esperado y mostrado en la primera imagen de requerimiento.

Ojala esta solución les sirva para resolver situaciones de modelado recursivo. Recuerden que si podemos ejecutar esto en SQL en nuestra capa de transformación, sería lo mejor para construir la dimensión. Como siempre pueden descargar el archivo de ejemplo de mi GitHub.

[DAX] INFO functions

Hace varios meses ya que microsoft nos ha sorprendido agregando nuevas funciones en DAX que responden a información del modelo. Conocer detalles del modelo se vuelve indispensable para documentar o trabajar por primera vez con un modelo ya creado.

Ya son más de 50 nuevas funciones que permiten preguntarle al modelo detalles particulares como por ejemplo indagar en las expresiones de las medidas de nuestro modelo o los roles de seguridad por filas creados.

Lo cierto es que ya existía una forma de llegar a esta información. Desde el inicio de modelos tabulares tuvimos exposición a DMV (Dynamic Management Views). Como nos gusta hacer aqui en LaDataWeb, primero veamos el contexto teórico:

Las vistas de administración dinámica (DMV) de Analysis Services son consultas que devuelven información sobre los objetos del modelo, las operaciones del servidor y el estado del servidor. La consulta, basada en SQL, es una interfaz para esquemas de conjuntos de filas.

Si quieren traer un poco más a la memoria o un ejemplo de ello, pueden revisar este viejo artículo. El nuevo esquema INFO en DAX nos brinda más de 50 funciones para obtener información del esquema TMSCHEMA de DMV.

Si ya existía... ¿Por qué tanto revuelo?

Las INFO de DAX vienen a evolucionar algunos aspectos que no podíamos resolver antes y darnos creatividad para explotarlos en otros que tal vez no habíamos pensado.

No es necesario utilizar una sintaxis de consulta diferente a DAX para ver información sobre tu modelo semántico (antes SQL). Son funciones DAX nativas y aparecen en IntelliSense cuando escribes INFO.

Puedes combinarlas usando otras funciones DAX. La sintaxis de consulta DMV existente no te permite combinarlas. Como función DAX, la salida es de tipo de datos Tabla y se pueden usar funciones DAX existentes que unen tablas o las resumen.

Estas son el eslabón inicial bajo el cual se llamó la atención. Ahora podemos pensar solo en DAX y si buscamos INFO de Tablas, relaciones, columnas o medidas, podemos combinarlas para mejorar el resultado de nuestra consulta. Si quisieramos conocer las medidas de una tabla puntual con su nombre, podríamos ejecutar algo así:

EVALUATE VAR _measures = SELECTCOLUMNS( INFO.MEASURES(), "Measure", [Name], "Desc", [Description], "DAX formula", [Expression], "TableID", [TableID] ) VAR _tables = SELECTCOLUMNS( INFO.TABLES(), "TableID", [ID], "Table", [Name] ) VAR _combined = NATURALLEFTOUTERJOIN(_measures, _tables) RETURN SELECTCOLUMNS( _combined, "Measure", [Measure], "Desc", [Desc], "DAX Formula", [DAX formula], "Home Table", [Table] )

Así obtendríamos una tabla con su nombre, sus medidas, sus descripciones de medidas y las expresiones de las medidas. El resultado puede ser documentación de modelo exportado a excel:

¿Donde o cómo puede ejecutarlo?

Las funciones de información puede ayudarnos para explorar un modelo en edición actual. Si estamos conociendo un modelo por primera vez o culminando un trabajo para documentar, podríamos abrir la vista de consultas DAX de un Power Bi Desktop para ejecutar el código. También siempre dispondríamos de DAX Studio que no solo permite ejecutar con un PowerBi Desktop, sino también contra un modelo en una capacidad dedicada en Fabric o PowerBi Service.

En mi opinión lo más interesante es que esto es DAX nativo. Como gran amante de la PowerBi Rest API, eso me entusiasma, dado que el método que permite ejecutar código DAX contra un modelo semántico en el portal de PowerBi, no permite DMV. Restringe a DAX nativo. Esto abre las puertas a ejecutar por código una consulta de información al modelo. Podríamos estudiar y comprender que es lo que a nuestra organización más nos ayuda entender de un modelo o nos gustaría documentar. A partir de ello construir un código que obtenga esa información de un modelo semántico que necesitemos comprender. Veamos la siguiente imagen que aclare más

Espero que las funciones los ayuden a construir flujos que les brinden la información que desean obtener de sus modelos.

Excel Power Query vs. Power Pivot: Which Tool Should You Use?

If you’ve ever worked with large datasets in Excel, you’ve probably reached a point where basic formulas just aren’t enough. That’s where two of Excel’s most powerful features come in: Power Query and Power Pivot. Both tools are essential for data analysis, but they serve different purposes.

So how do you decide which one to use? In this guide, we’ll walk through the differences between them and help you figure out the right tool for your needs.

What Is Power Query in Excel?

Power Query in Excel is a tool designed to clean, transform, and prepare data for analysis. It allows you to import data from different sources, fix formatting issues, and shape the data exactly how you want it, all without changing the original files.

Key Benefits of Power Query:

Connects to many sources: Excel files, text files, databases, online sources, and more.

Cleans data efficiently: You can remove duplicates, split columns, filter rows, and convert data types.

No need for coding: Its visual interface makes data prep easy, even for non-programmers.

Keeps a clear log: Every step is recorded, so changes are easy to trace or undo.

If you regularly work with messy data from different departments or systems, Power Query is the tool that helps you get it all in one place and ready to go.

What Is a Power Pivot? A Practical Tutorial

Power Pivot is an advanced data modeling feature in Excel. Instead of just working with a single flat table, it lets you work with multiple related tables. You can create relationships, use calculated fields, and build powerful pivot tables from huge datasets.

What Power Pivot Does Best:

Handles big data: It can work with millions of rows without slowing down.

Creates relationships: You can link multiple tables without merging them.

Supports DAX formulas: These allow you to create advanced calculations that go beyond standard Excel functions.

Improves reporting: Helps build dynamic dashboards and pivot tables based on complex models.

If you’re building reports that need to pull information from several tables, Power Pivot will save you hours of work and improve the quality of your analysis.

Power Query vs Power Pivot: A Side-by-Side Comparison

Let’s break it down clearly:FeaturePower Query in ExcelPower Pivot TutorialMain Use Preparing and transforming data  Modeling data and running advanced       calculationsStrength Connecting and cleaning data from   sources Creating relationships and custom   measuresInterface Step-by-step visual editor Data model view with DAX supportIdeal For Standardizing messy input data Analyzing large structured datasets

So, Power Query is for cleaning and prepping. Power Pivot is for modeling and analyzing. Simple as that.

Using Both Tools Together

You don’t have to choose between them. In fact, combining both tools gives you the best results.

A Typical Workflow:

Start with Power QueryLoad the data, clean it, and apply all your transformations.

Move to Power PivotCreate relationships between the tables, define measures, and build your reports.

This combination is what makes Excel a real powerhouse for data analysis. It’s a workflow many professionals use daily.

When to Use Power Query

Here are situations where Power Query is the better choice:

You need to import data from multiple sources.

You’re dealing with messy or inconsistent data.

You want to automate data cleanup tasks.

You need a repeatable process that updates with fresh data.

If you find yourself repeating the same steps every time you get new data, Power Query can handle all of that with just one click.

When Power Pivot Is the Right Tool

Use Power Pivot when:

Your data is too large for regular Excel to handle efficiently.

You’re working with multiple related tables.

You want to build custom KPIs and metrics.

You need to create a dynamic dashboard with slicers and filters.

Power Pivot is perfect for business analysts who need to dive deep into data and build powerful reports without leaving Excel.

Final Thoughts

Understanding how Power Query in Excel and Power Pivot work, And how they work together can completely change the way you use Excel. They are part of a bigger trend of self-service BI tools, giving more power to users without relying on IT or external software.

Use Power Query to clean and organize your data.

Use Power Pivot to model and analyze it.

Use both tools to build a streamlined, automated workflow that saves time and improves accuracy.

If you’re serious about improving your Excel skills, learning both tools is a smart investment.

How to Prepare Your Tableau Team for the Power BI Learning Curve

As more organizations pivot toward Power BI for its tight Microsoft integration, cost efficiency, and advanced features, many Tableau teams are facing the challenge of adapting to a new environment. While both platforms offer powerful data visualization capabilities, they operate under different paradigms. For a smooth transition, preparing your Tableau team for the Power BI learning curve is crucial. Here’s how you can set your team up for success.

1. Acknowledge the Differences Early

Start by educating your team on the key differences between Tableau and Power BI. Power BI’s model-driven approach, its reliance on DAX (Data Analysis Expressions), and its integration with the Microsoft ecosystem require a different mindset compared to Tableau’s more visual, worksheet-based structure. Teams need to understand that while many principles are transferable, workflows and tools will feel different.

2. Invest in Tailored Training

Generic tutorials won’t cut it. Your Tableau experts already understand data — what they need is training that bridges their current Tableau skills with Power BI’s capabilities. Look for training resources specifically designed for Tableau users transitioning to Power BI. Include hands-on sessions that focus on building similar dashboards and reports in Power BI to reinforce familiarity.

3. Encourage a DAX-First Mindset

Unlike Tableau’s calculated fields and LOD expressions, Power BI relies heavily on DAX for complex calculations and data modeling. DAX can initially be intimidating, but it’s essential for optimizing performance and building scalable reports. Provide your team with foundational DAX training and encourage daily practice to build confidence.

4. Start with Pilot Projects

Don’t throw the entire workload into Power BI on day one. Instead, assign low-risk, internal dashboards as pilot projects. This allows the team to experiment, make mistakes, and learn in a low-pressure environment. Use these pilots to document best practices and build internal playbooks that will help others follow suit.

5. Use Tools Like Pulse Convert to Accelerate Learning

Manual migration from Tableau to Power BI can be time-consuming and error-prone. Leverage tools like Pulse Convert by OfficeSolution to speed up the transition. Pulse Convert automates many aspects of the migration process and helps Tableau users see how their existing logic and dashboards translate into Power BI, making the learning curve significantly less steep.

6. Foster a Culture of Collaboration and Support

Lastly, create a support network where your team can openly share challenges and solutions. Regular check-ins, lunch-and-learns, and collaborative problem-solving sessions can make the transition feel more like a team effort rather than an individual struggle.

Conclusion

Preparing your Tableau team for the Power BI learning curve requires more than just technical training—it demands a thoughtful, structured approach. By acknowledging platform differences, investing in targeted learning, and using smart migration tools like Pulse Convert, you can empower your team to make the leap confidently.

Coupa Supplier Management: Elevate Procurement with Precision

Supplier Management functions in Coupa provide companies with an advanced solution to manage supplier lifecycle stages across onboarding through qualification, followed by performance assessment alongside compliance verification. The business process automation capabilities in Coupa consolidate supplier data for risk mitigation while enabling supplier compliance and generating auditable records.

An organization's success depends directly on the capabilities of its users with regard to tools. The framework of coupa training stands imperative for success at this point. We at Tech Innovations deliver training solutions that combine instructor-guided instruction with independent learning modules based on your organization's particular requirements.

ServiceNow Implementation: Automate and Streamline IT Operations

When implementing ServiceNow with success, organizations receive a digital workflow infrastructure that automates IT services management (ITSM), HR services, and security operations alongside more functions. ServiceNow enables teams to become more efficient by eliminating manual work while delivering faster results and achieving better departmental transparency.

The combination of ServiceNow and Coupa brings additional strength to the system. The system performs automatic flows to start compliance audits in Coupa whenever an IT incident detects cybersecurity issues from suppliers. Automated workflow activities between different functional teams create responsible processes that break down organizational departments.

Power BI Integration: Turn Data into Insights

The power of Coupa and ServiceNow functionality becomes truly magical upon analysis and visualization of your data. Powerbi integration serves as the solution in this case. When Power BI links to Coupa and ServiceNow, businesses can create interactive dashboards that unite procurement information with IT and supplier data.

Complete monitoring of supplier performance requires assessment of price, delivery speed, and regulation adherence.

Track the duration of IT request resolutions while identifying the locations where the processes are getting stuck.

Procurement teams can achieve full visibility through the combination of operational KPIs fetched from Coupa and ServiceNow platforms.

Analyzing past information will help predict upcoming supply chain threats.

To help teams take full advantage of these capabilities, we offer hands-on Powerbi Tutorials. The instructional materials guide people through dashboard development before moving on to data modeling and DAX application for advanced insight discovery. Our resources provide help at both basic and advanced levels to any person who works with Power BI.
