In this blog, we will explain an advanced topic about the M language – using List.Generate to loop over a table. We will combine our knowledge of lists, records, functions, iterations, and looping techniques. Basically, every important object in PowerQuery. Do-while Loop in PowerQuery Do while loop is commonly used...

In this article, we are going to talk about cleaning and transforming column names dynamically and in a bulk. The article was inspired by a request from a client who had issues exporting data from its data warehousing program to .csv files. Out of an unknown reason, program was adding...

 In this article, we will see how we can use the self-referencing technique and Dataflows to create incremental refresh with PowerBI Pro version. This technique is tested and working both with cloud and on-premises data sources. In case you are using on-premise data sources to access new data, you need to add on-premise source...

When creating a budgeting prediction, most of the time we are creating it on the higher granularities. Rarely we do it on a daily basis. But sometimes we are required to match budgets to actual sales on lower granularities than the one we previously set (e.q. the manager wishes to...

High cardinality columns are often the problematic part of the data modeling in most environments, including PowerBI. Since the PowerBI data model resides on a columnar database, having high cardinality columns impact both performance and the size of the model. This is especially the case with columns having more than...
