For clients using Unanet Financials, a default posting organization MUST be assigned for any of your legal entities. No posting processes can successfully process if this value is left blank.
The Default GL Posting Organization is set in the Organization that represents the Legal Entity. See the screenshot below, where the Organization has been designated as a Legal Entity by selecting"This organization is a legal entity" with a Default GL Posting Organization set to "STARK" (selected from the dropdown menu).
This designation is made on the Financials tab of the Organization. This allows for the posting processes to be successful.
