BADI for ME27

Dear all,

Is there a BADI available for ME27?

The scenario is such that the client wants to make the POu2019s through ME27 only and not through ME21N

We have used the BADI ME_PROCESS_PO_CUST and put the code in PROCESS_ITEM and getting the required result as desired.

But this BADI does not trigger when creating a PO through ME27.
