We are posting accruals from Vistex through enhancement. When accruals are posted from vistex an accounting is generated into COPA (as per information from COPA) with a unique document type which is not used for other transactions.
We need to populate certain characteristics for these accrual postings from COPA.
The way see it is that we have to create an enhancement/derivation rule with a condition that the custom characteristics must populated only for the postings for this specific document type.
Is my assumption correct? Is there any other way to populate these custom characteristics created for capturing accrual data posted as a FI document.
