Idocs not populating the fields

Hi

We are using Extended Classic Scenario. After the shopping cart is approved, the PO is generated in the backend R/3. The PO is generated in the backend and the idoc is triggered which is sent to supplier.

The problem we are facing is as below:

There are some fields in the idocs which are not getting populated. We are using badi implementation BBP_PO_INBOUND_BADI in the backend. We have used both the methods BBP_MAP_BEFORE_BAPI

BBP_MAP_AFTER_BAPI

The table EKPO is getting updated but the idoc does not have the fields.

Also when we are second time retriggering the output the idoc is having the required fields.

Kindly advice.

Thanks and Regards

Manoj
