Merged dimension calculation problem

[#1]

Hello I have a merged dimension called "Proj.code project" (2nd line of the table)

I want to add up each "Item Code Fact." (1st column left) f

or any project code I want to get the table found on the right.

However the second column from the left is a merged dimension and I think this is problematic in my formulas

If I understand you correctly, then you should use ForEach([Item Code Factor]).
