When a user submits a Free Text Invoice (through AR) or a Pending Invoice Journal (through AP) it should validate the Account & Dimension Combinations prior to submitting.

If the combinations don't validate the user should not be able to submit.

This behaviour exists for Purchase Orders and Employee Expense Reports.

Having to withdraw the Invoice, change the dimensions and resubmit through the workflow can take a lot of time, especially if the workflow is quite complex, this process could be missed if the invoice is not able to be submitted without valid dimension/account combination.
