can anyone tell me what is the difference of usage for field status group in posting key and GL account as i notice the fileds are the same. during data entry, system will check both field status or how?
Both are to control the field status of the line item.
But, the FSG of the Posting Key and the GL FSG status should not clash like below.
Take 'Assignment' field as example :
Posting key FS - Suppress & GL FS - Required - will give you error message at the time of posting
Posting key FS - Required & GL FS - Suppress - will give you error message at the time of posting
Otherthan the above, all other combination works
