The release of invoice documents that have been completed for posting is supported by a link to a workflow procedure.

In the release step, the person responsible for releasing the invoice document decides if it should be released. The system uses the virtual attribute ReleaseAgent for object type BUS2081 to determine the person responsible for releasing the document. The release criteria in Customizing for Logistics Invoice Verification are checked for this.

• If the person responsible decides to release the document, it is first released in the background and then posted.
• If he or she decided to reject the document, it is forwarded for further processing to the accounts payable clerk responsible for completing invoice documents for posting. The rejection reason should have been entered using the memo function.

The accounts payable receives a work item in his or her inbox. In this work item, he or she can read the reason why the invoice document was rejected and change it. If the accounts payable clerk parks the changed invoice document, saves it as complete, deletes it, or posts it, the workflow ends. It makes sense to save the invoice document as complete and therefore trigger the release workflow again, assuming that the invoice document is subject to release.

If the invoice document is parked, deleted, posted, or released in the background outside the workflow process, the workflow ends.
