How to change Inspection lot quantity for inspection type 17 after GR cancellation in EWM system

Hi,

For a material we have activated inspection type 17 in ECC system and maintained inspection inspection rules in EWM system.

we have done inbound delivery in ECC and GR in EWM, inspection lot with inspection type 17 generated in ECC.

Due to some reason we want to change the GR quantity.

for the same we have reversed GR and cancelled inspection lot in EWM and inspection lot is cancelled in ECC.

Now we are unable to change the quantity and redo the GR.

Please Help
