We are trying to post a P&L journal entry into a prior period (12) in the previous fiscal year (2007). The period 12 in 2007 is open. The two P&L accounts involved in the transaction have been defined with a P&L statement account type in the master data. We have a GL account maintained for this PL account type in the config. But this GL account is not created in our company code.
We were able to post the P&L documents in this company code during the entire 2007. But we are not able to do it now.
What could be the possible reason? I am aware that creating the retained earnings GL in our company code will solve the issue, but I would like to know how were we able to post all thru 2007 and not now.
