Process againest 122 Mvt

Hi Gurus,

I had created Po for a material ordering 1000 KGS. I had posted the GR for 1000 KGs and Posted simultaneously IR for 1000 KGs.

In process I found some of the material was damaged , hence posted 122 Mvt (returns to vendor). In this case, how can I recover the amount from Invoice posted amount.

What I need to post to recover the Invoice amount for the damaged quantity. Please advise

Regards,

Subbu
