Double posting of credit memo results duplicate entries in item ledger

Hi All,

Hope all is well!

One of our users create and post service credit memo twice. When I checked the ledger entry for credit memo A I cannot find the item ledger, no item ledger in the navigate. But when I checked for the credit memo B, the entries were doubled. Then I am puzzled how does it happen that the entry for credit memo A has been lost and doubled the entry in credit memo B.

Hope you can help me to understand it.
