Vendor return delivery for excisable goods

Hi,

I have few queries regarding vendor return delivery of excisable items.

1) MIGO is done- Part 1 is done

J1IEX_P- Part 2 is done.

MIRO is done/not done.

2) MIGO is done-Part 1 is done.

J1IEX is not done.

MIRO is not done.

3) In case of return PO, when we do MIGO with 161,

should I select Create excise entry or No Excise Entry??

What will be correct vendor return delivery procedure??

I've searched forums, but I'm not able to get the proper solution for excisable items.

Can anybody tell me step by step procedures for above.

Thanks in advance,

Regards,

Piyush
