Incorporate PO Release Strategy in custom workflow
I have a requirement to incorporate the PO Release Strategy into a custom process followed by the client. The client has a unique Approval Form which needs to be approved as per the PO Release Strategy before creating the PO. How do I go ahead with this requirement. I need to know it's possibilities using Custom Workflows / BAPI's / etc.
I tried finding data to link the amount --> release codes --> designations --> sap userid's, to replicate the scenario, but in vain.
Kindly help with hints asap.
