Power Query Editor: custom column based on another table
I found a solution. In the SupplierTbl, I can add rows for dates between start and end dates.
(following instructions I found here: https://natechamberlain.com/2018/08/08/how-to-add-rows-for-dates-between-start-and-end-dates-in-power-bi-date-range-data/)
That way, I can merge by matching MaterialNbr, Plant code, and Date.
You've been very helpful, thank you! That works well, expect for one thing: I now have some duplicate row here and there. That seems to happen for a Material number that has 2 row or more in the SupplierTbl.
I need to hide these duplicate rows because I will later sum up the Cost and I don't want to double count. I'm working on it but if you have any suggestion in the meantime, I'll take it.
If your supplier table has duplicate records you can go to that table, select the fields that would make up a primary key and right click > deduplicate
