As per the buisness requirement, the GR against PO and GI against Process Order occurs packwise. For example GRN occurs against PO for 100 kg in 10 packs of 10 kg each. Similarly GI can occur against process order for 55 kg (5 packs of 10 kg each and 5 kg from 6th pack). I want to trace this GR and GI in SAP pack wise. Kindly let me know any functionality in SAP which supports this.
