Returns from 2 Plants

Hi

I have a sales cycle from 2 plants, wherein the system creates a 2 deliveries automatically after creating an order. We just have to go in VL06G and do PGI and then VF01 to create a billing document.

Now the problem is the returns cycle is not working. Can anyone suggest.

I am able to create a return order but what next?

Please suggest.

Thanks & Regards,

Vinod
