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.
Bring your supplier field into the transaction table with a merge. Select both the Material number and plant code as the keys to join, then with your newly merged column you can create a new calculated column to handle the transaction date logic.
You can then delete your merged column and just have the calculated one.
Thank you for your help!
That's progress, but after merging, I'm getting a new column with "Table" instead of actual records. What should I do next?
An important detail: in SupplierTbl, I may have multiple records with teh same MaterialNbr and PlantCode, but different contract start date and contract end date and different supplier. For example:Material Nbr Preferred Supplier Plant code Contract start date Contract end date 123456 ABC Corp XYZ 1/1/2023 4/30/2023 123456 DEF Inc. XYZ 5/1/2023 987654 GHI & Co WER 2/1/2023
