Supplier invoices cannot be approved in My Inbox because of an error with the posting periods.
SAP S4 HANA Cloud
Reproducing the Issue
A supplier invoice is saved as completed, for example with posting date 08/08/2020. In the Manage Workflows for supplier invoices app, there is an active workflow for the scenario Workflow for Parked Invoice as Complete. Based on the workflow definition, the approver(s) receive the invoice in their inbox for approval.
At a later date, the approver tries to approve this invoice in the My Inbox app. When the release button is pressed, there is an error: "Cannot process task. For more information, see the details." Displaying the details shows the error about the posting periods. "Allowed posting periods: 10 2020 / 09 2020 / 12/2019".
In Materials Management posting is possible in three different periods: current period, previous period of the last fiscal year, and if backposting is activated, in the previous period as well. Backposting can be activated in the app Allow Posting to Previous Period (MMRV). It is not possible to post invoices outside of these three periods.
Since invoice posting cannot be done in closed periods, the posting date has to be corrected first.
- If the workflow is configured with "Rework Invoice", then the approver can reject the invoice, which is then sent back to the original processors inbox. The invoice processor can correct the posting date, and save the invoice as completed again. This will restart the workflow and then after the approvals are done, the invoice is going to be posted.
- Using the Schedule Supplier Invoice Jobs - Advanced app, and the template Mass change posting date, it is possible to change the posting date of the parked invoices. This does not influence the workflow and approval status, so after this is done, the approver(s) can proceed with the approval.
