Issue with Retrieving Linked Credit Memo Details via REST API

Hi Team,

We have a requirement to update the AllowCompletion flag to 'Y' and the CreditMemoStatus to 'Complete' on 'Incomplete' Credit Memos using the REST API. To achieve this, I'm using the GetAll REST API to first retrieve the CustomerTransactionID for the specific Credit Memo, and then using that ID to update the fields mentioned.

The issue we are encountering is that there are two types of Credit Memos: standalone Credit Memos and Credit Memos linked to an AR invoice. While I am able to retrieve details using the GetAll REST API for standalone Credit Memos, I am unable to retrieve them for Credit Memos linked to an invoice.
