Are you using the SDK, Jean? This doesn't sound like a topic for the General discussion forum. Can you provide more information so we can hopefully get you to the appropriate group.

Yes, I am using the SDK.  Which area should I post my questions?

Moving this post to the Sage 50 US SDK forum.

Thanks,

Derek

I found a solution by creating the AccountList object, retrieving the GUID for the entry and then using that GUID in the declaration for EntityReference<Account>.  The return value succeeded and the subsequent call to add a journal entry was also successful.   This issue has been resolved.
