Workflow: Approval BAPI

Hi,

After to load all purchase orders from a system to SAP-SRM, the manager changed his mind about the workflow. He does not want to approval all purchase orders documents loaded, as workflow asks to. So, he asked me to make a program witch could make that instead him.

I could not find any BAPI or any way to do that by configuration at WF as well.

Does anybody know how could I do that?

Thansk for any help.

Karla.
