BP Idoc always tries to Create BP, even for Update scenarios.

Hi Experts,

We are implementing MDG-C and currently facing an issue because of which Idocs are failing in target ECC system.

On a Customer creation in MDG we replicate BP Idoc to target the ECC using BUPA_INBOUND_MAIN_SAVE_M09 .

Everything works well in case of Create scenario Object_Task is "C"

However, in case of update/block/delete scenarios the Idocs have same "C" value in Object_Task and this is causing BP Idoc to fail in the target ECC system as it tries to create BP which are already present.

For configuring I used this link -

Question - How can I ensure that in Update scenario BUPA_INBOUND_MAIN_SAVE_M09 has Object_Task as "U" and in create scenario it has "C"?

Is there any configuration in BUPA_CALL_FU I am missing?

Please advise.

Thanks,

Ravi
