cannot hide 'Project Subobject' column in CATS regular.
I am trying to hide standard columns from CATS regular (timesheet).
I was successful to hide columns 'Project' and 'Project Description', but column 'Project Subobject' cannot be hidden! it still shows up in ESS.
I do this from IMG Employee Self-Service->service-specific settings->working time->record working time->define field selection->Data Entry Section->Project Subobject (this is field CATSFIELDS-CPR_OBJTEXT).
Any idea why this particular field cannot be made invisible?
