Problem is that after goods receipt and AFTER invoice verification, is being done. Client wants this more controlled as the GRIR account is being affected. So no reversals to be done after Invoice verification. How to approach this?

Make this setting: SPRO > Materials Management > Inventory Management and Physical Inventory > Goods Receipt > For GR-Based IV, Reversal of GR Despite Invoice

Here remove the tick against Mvt 102 & 122.

Now the system will not allow to return the Good at any case.
