Creating Logic within Power Query Editor?
Hi all,
Novice PowerBI user here. I have a few queries that I have loaded within a workbook, and I'm attempting to create a column within that table that looks at ANOTHER table, takes the latest date we have (in this case, would be 6/14/2021), and populates the column with it.
Is there some easy way to figure this out, or am I grasping at straws?
Hey Anonymous ,
this is not easy as one would hope, this is because referencing other tables (other queries) from within a query requires some M code.
Then you can consider using List.Max (<List.Max - PowerQuery M | Microsoft Docs) in combination with Table.SelectColumns (Table.SelectColumns - PowerQuery M | Microsoft Docs) to store the MAX date.
If you need more guidance, create a pbix that contains sample data, but still reflects your data model. Upload the pbix to onedrive or dropbox and share the link. If you are using Excel to create the sample data, share the xlsx as well.

Tom

Hi Anonymous !
You can first create a relationship between these table, like any joining key which is common in 2 tables, then use RELATEDTABLE() DAX function to achive the results;

Maybe you will find some time to provide a short outline of your solution and mark your post as an answer, as this will help others who have similar questions.
