Expense report line Financial Dimensions are validated currently against the setup in the GL module, such as the Configured Account Structures and Advanced Rule Structures. All GL transactions need to be validated the same way, whether they originate from expense report lines or the header.

When a user clicks Submit to workflow, if there are any invalid account + financial dimension combinations, they will receive an error message and must correct the accounting before it will allow submit to workflow. The same validation should occur at the Header level of the expense reports to avoid users submitting expense reports with invalid header (AP) account + financial dimension combinations.
