Customer is using form called “Post project invoice proposals” (Project management and accounting > Periodic > Project Invoices > Post project invoice proposals) to post the ‘Approved’ Invoice proposal created.

Here customer is getting invoice proposals with the status of ‘Approved’ as well as status Open’ and Open status are being considered for posting. Instead of only Approved Invoice proposals and sent to the clients.

The system is just not only showing Open project invoice proposals in the form, but it posts them without passing through the workflow approval process.

Customer is having misplaced information on posting of Invoice proposal. It's allowed to post project invoice proposals without being approved.

The expected behavior is that only the invoice proposals that are set as ‘Approved’ should only be considered for posting, when there's workflow is enabled strictly.
