Hi Mynda, I'm learning in bits and pieces and still trying to wrap my head around the utility of Power Query.
I have a table of sales 'SalesMovements'. And I have table of stockcodes 'InventoryMaster'. I just want to list sales for 2 different periods next to each stockcode and then do some math to calculate weekly averages:
SKU | Prev 8 Mo Sales Weekly Avg | Prev 3 Mo Sales Weekly Avg
I could easily accomplish this by creating two query tables (one for 8 months of sales and one for 3 months of sales by stockcode) and then using SUMIFS in my Inventory sheet over each table. But I really want to utilize PQ and the data model - and especially the extensive Date functions in M - to calculate these totals and populate my Inventory worksheet. I've learned a bit about custom functions, value types, lists, etc, but I can't yet see how it all hangs together in order to find a starting point.
What would you suggest?

Hi Jeff,
Welcome to our forum!
It's difficult to say without seeing the structure of your source data and an example of the desired result. Can you share a sample Excel file with the query you've built so far and how you'd like the end result to appear?
