Return Delivery by 161

Hi All,

I want to know the standard 161 - return delivery scenario, please explain.

I am doing in following way.

1) PO created with return indicator, taxes included as per original PO for which material has to be returned with same price

2) Chapter Id, cenvat determination entered in J1ID

3) GR created & excise captured and post( Is it correct to post excise at Gr-161? & what will be impact on excise register please explain)

4) Similarly account document created at the time of GR-161

5) During J1IS warning message appeared that already excise invoice exists.

6) J1IS saved and excise document is created message appeared

Please correct if any changes required to be done and if anything i am missing.

Regards,

Umesh
