We're trying to partially credit a prepayment invoice using these steps:
https://docs.microsoft.com/en-au/dynamics365/business-central/finance-how-to-correct-prepayments
However, Step 4 doesn't work because from Step 3 a CR/Adj note is created for the full amount and posted. Once it's posted, we can't go back and adjust the amounts to create a partial credit.
The obvious next step is to simply create a CR/Adj note manually and apply it to the prepayment invoice. However, the posting gets stuck at "Posting to bal. account".
