We have a client committed a mistake in recording JE. Here's the scenario;
1.) Books of accounts of 2008, 2009, 2010 and 2011 are already closed
2.) On January 1, 2012, the user cancel the period end closing of 2008. The original record of 2008 in period end closing was Credit to Expense and Debit to Retained earnings.
3.) After she cancelled that entry, the record was Debit to Expense and Credit to retained earnings.
4.) This procedure affects GL accounts and trial balance but it doesn't affect the Profit and Loss statement of SAP.
5.) The result is the GL balance of 2012 for that expense accounts vs. the P&L account is not tally.
6.) Now, how can we adjust the GL account without affecting the P&L for January 2012 or how can we adjust the P&L without affecting the GL?
Please help. I made all the trial and error entry to revert the original data but I failed to come up with a resolution.
