Finding Average Item rate while grouping by Item code for a date range (slicer)

Hi again DaGemsta

Firstly you are being a bit cheeky adding a new problem to the ticket. 😀

Please raise 1 problem per ticket. If you need to change or expand the ticket because you did not ask the right question, them accept the solution and raise a new ticket and give the solver twice the kudos scores for doing twice the work. Thank you. 👍

Secondly, you have now mention a "Received" field which is not is you example data ! 🤔

May I suggest that you never use / in Power BI.
Always use DIVIDE to capature any divsion by zero errors. 😇

I cant answer you exact questioin because you hace not provided the  "Received" field, but I am pretty sure this info will help.

Look at these 2 measures carefully:-

Sum value =  SUM('Table'[Originally Ordered Qty]) * [Ave rate]

Both will return the same answer for each a row in table visual with

Document number, Date, Item, Item Rate, Ave Rate, Sum value, Sumxvalue.

However, only the Sumx value will return the correct sub totals and grand totals.

This is because SUMX is an iterator.  see https://docs.microsoft.com/en-us/dax/sumx-function-dax
