The reason why the formula is not working is because the dimension in "DIM00_Input Data" Module and the dimensions in these modules "ATT05", "ATT12", "ATT09", "ATT16", "ATT15", "ATT02" which are referenced in the "check" line item are different. And so the formula is looking to the parent or top level of these modules to fetch the data and it is turning out to be empty.
You can either put the formula using code function and reference the line item in the same module for each like below:
I am not sure exactly whats you scenario but if your scenario is to check if any of the 6 line items is empty then the "check" must become true , then instead of using Isblank the above way, you should use the formula as
isblank('company code') or isblank('product family') or isblank('ownership') or code('Chart of Account') or isblank('Market') or isblank('Local Currency')
Thank you for your reply, indeed the scenario is to check if the input data are correctly filled (choose by user form the list- I'm referring to the lines (Company Code, Product Family, Ownership ... formatted as list).
The formula it's not working ....
I used also the last one (isblank('company code') or isblank('product family') or isblank('ownership') or code('Chart of Account') or isblank('Market') or isblank('Local Currency')) , but I have the same result, it's not working even if one of the line item it's blank.
