Customer is requesting for different posting profiles for project credit notes. These are required to be posted with different ledger account with impact to customer sub-ledger than original invoices, i.e. different posting profile must be used for credit notes.

Currently this is not supported in standard D365 solution. There is no possibility to select different posting profile in the project invoice proposal create as credit note. Posting profile is strictly defined in the project contract defined to project ID. Both invoice and credit note are linked to same project ID, so also to same project contract.

For ex:
I have a project A with invoice posted with ledger account 123 on debit side. When I create a credit note I would like to post credit note with ledger account 456 on the debit side to be able to differentiate credit notes and invoice within reconciliation between trial balance and sub-ledger books.

Original transaction posting will be considered as below:

Original invoice is settled with credit note in customer's sub-ledger and closed. Settlement customer transaction is created automatically, where both ledger accounts are balanced.
