Hi @algrigore 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: isblank(code('Company Code') & code ('Product Family') & Code('Ownership') & code('Chart of Account') & code('Market') & code ('Local Currency')) or you can reference the "ATT05", "ATT12", "ATT09", "ATT16", "ATT15", "ATT02" line item in the module and use lookup after each reference like below isblank('ATT05 CMC02 Company Code L2'.code[lookup:'Company Code'] & 'ATT12 module'.code[lookup:'Product Family'] & 'ATT09 module'.code[lookup:'Ownership'] & 'ATT16 module'.code[lookup:'Chart of Account'] & 'ATT15 module'.code[lookup:'Market'] & 'ATT02 module'.code[lookup:'Local Currency']) 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') Hope this helps.
