Hi

we are facing problem in settlment of some auc assets . we are follwoing internal order based auc settlement . error messgae is appearing as

"posting not possible(Posting year earlier than capitalisation year) . This issue is there due to some erong posting which has alreday been reversed but the capitalisation date has got updated in auc asset master record.

Pls suggest.
