Automating PO creation for a sub-contracting PR

Hello,

We are trying to automate the creation of PO following the creation of a sub-contracting purchase requisition (type L). Can any one explain me the detailled procedure?

The PR is manually created. It.s not a PR suggested by the MRP.

I also need to define only my renovable or re-shapable items(stock items) as the ones that we can automate the PO creation.

Waitng your urgent help and support.

Thank you in advance,

C. Oumar Mbow
