Remove partial PGI

Hi Guru,

My requirement is to chnage the scheduled quantity of schedule lines because goods was not deleivered/partial delivered.

This is a STO scenario. But PGI has been done in delivering plant.

When I want to change the schedule quantity, system gives message that schedule quantity can not be less than issued quantity.

Hence I want to reverese the PGI.

I cant use the T code VL09 as it reverse the complete PGI. I want to reverse only one item, but this PGI document has other line item as well.

There is one more schedule line for which partial quantity was received while PGI was one for full quantity. How to reverse PGI for partial quantity.

Need your help as its little urgent.

Regards
