Description of the issue:

- Free text invoice has been created with a posting date in March and submitted to workflow

- While workflow was being processed, March period has been closed

- Workflow has been Approved.

- Attempt to post the approved invoice: An error message appears to indicate that invoice can't be posted as period is closed

Expectation: A message proposing to post the invoice on the next open period like for the vendor invoice workflow process rather than modifying the free text invoice and submit it again the workflow.
