How to do Reversal or Date rectification in a Credit Memo with Activity

 HI

1. We have a passed a Credit Memo in AR '

2. The transaction date of the Credit memo is wrongly put as 28-MAY-2010 instead of 28-MAY-2009

3. It has a Correct GL date of 28-MAY-2009

4. It is not posted to GL

5. It has activity attached, earlier it was applied to Invoices and later after finding the wrong date the Invoices were Unapplied to the Credit Note

Please some one let us know how to correct the Transaction date OR delete this OR reverse the above Credit Note
