Automatic Excise Invoice reversal in Sales return

Ours is a manufacturing plant.

We sell Excisable goods to our Customer.

Normal Sale Cycle:

VA01-VL01N-PGI-VF01

(Excise Invoice gets generated automatically in background as Invoice is saved)

Our Requirement:

Client wants to map Customer Returns Scenario.

I have gone through helpful notes and got clear with Return proccess(SD)

VA01-Return Order( w.r.t. Original Invoice)

VL01N- Return Delivery (w.r.t Return Order)--PGR

VF01--Credit Memo( w.r.t Return Order)

I need a solution for AutomaticExcise Invoice reversal as goods are returned by customer to Plant.

Our client wants that reversal should happen automatically in background.(at any stage either as PGR is done..or else)

Client doesnt want to go for J1IH-manual JV posting.

kindly guide me Configuration steps to achieve this with registers updations and a/c effects.

also correct me if i am wrong in above understanding.

Thanks ,
