Inbound Idoc serialization BobJ

Hello,

I am looking for help with being able to process Inbound IDOCS sequentially in ECC. Sending system is BobJ and no XI or HANA is involved.

Process code used: BAPI

Processing mode : Background

Custom function module is used for IDOC processing and is assigned to a custom business object method

Can someone please point me to the correct direction here with these questions:

1) What needs to be done in BobJ(sending system)

2) What needs to be done in ECC 6.0, SAP NW 7.5

Thanks,

Ravi
