Calculating value based on columns in two different tables
Hi - Newbie question...
I've searched hard for a solution to this question and have tried several different ideas but keep getting an error message or values that do not make sense.
I have two tables:
CustomerOrders
which contains several columns including ProductCode and QtyOrdered
and
WarehouseStock
which contains columns including ProductCode, StockQty and Warehouse
Packaged items ready for dispatch are in Warehouse 1
There is a Many-to-Many, two way relationshp on the ProductCode
To help production, I have created a report with a Matrix visual which shows the ProductCode in the rows, and then two columns - the QtyOrdered and the StockQty. The data is filtered on Warehouse = 1
This works fine
Now I want to display the shortfall in a third column.
Even a simple attempt to create a new column in the WarehouseStock using the Related DAX function
Shortfall= related(CustomerOrders[QtyOrdered])fails with the error
The column 'CustomerOrders[QtyOrdered]' either doesn't exist or doesn't have a relationship to any table available in the current context.What am I doing wrong?
Thanks in advance !
You would propose that you extract the product/item object into its own dimension table, which then feeds the inventory and backorder fact tables with a unique address of 1:* each.

"There is a Many-to-Many, two way relationshp on the ProductCode"
Please explain the rationale behind this decision. Please show your data model.
Here is an example of the data in the two tables
CustomerOrders
Date Customer Ref PurchaseOrderRef ProductCode QtyOrdered 01/01/2020 C-0091 PO-1234 A1 10 01/01/2020 C-0871 PO-9821 B1 20 02/01/2020 C-0020 PO-7212 A1 5 02/01/2020 C-0020 PO-7212 C1 20 02/01/2020 C-9817 PO-A0912 A1 12 From this I can calculate that I need A1 - 27 units, B1 - 20 units etc
Of course there is much more data in the table, so I am interested in the number of units required this week,and WarehouseStock
Warehouse Location ProductCode StockQty 1
A1 A1 100 1 C1 B1 12 2 R A1 50 1 Q A1 60 etc. I can calculate that I have 100
This structure is inherited from a third party package which we connect to via SQL so I have no control over the structure

Hi everyone,
I need help with solving one problem.
Take a look at this demo table:
We have 4 different columns, one is "client", the second one is "transporter". Some of our clients are also and transporter.
I want to make a mutual column and summarize money we earn cooperating with that client ( sum of SUM EUR) - Looking column "client" and "SUM EUR" column, and looking the "Transport" column and the column "price to transporter".I want to see how much money we give to transporters and how much they give us as a client we work for.
For example, "client 8" as a client gives us 420€, but we give "client 8" as a transporter 300€.
I just want to compare these two values with mutual clients I have in column "client" and column "Transporter".
Thanks in advance.
