Not able to approve supplier invoice through workflow

Hi,

I am trying to configure the Approve Supplier Invoice Fiori application. I have done all the necessary configuration.

1. Activated workflow WS20001004, assigned the agent necessary to take the decision.

2. Defined release group to the vendor master.

3.Defined release criteria for the workflow agents.

4. You have specified the workflow tasks that are relevant for approving supplier invoices. You do this in Customizing for Materials Management under Logistics Invoice VerificationApps for Logistics Invoice VerificationApprove Supplier InvoicesSpecify Workflow Task IDs
