Acquisition value negative in area 01

Dear Friends:

when posting a credit memo to asset using FB01,the user is getting the error "Acquisition value negative in area 01". I have read in the forum that this error occurs if balance carry forward is less or a balance which is lesser than the current credit value .

I there any other reason when the credit memo is not getting posted? If the above solution is correct, what are the t.codes used to analyse the issue?

Please advise?

Thanks&regards
