My client manufactures robots.There is one FG, to make this there are 2 SFG (one is mech assemble & 1electric assemble). while making electric assemble there are 10 RM are consumed to make this. In production line if one electric component get rejected then it will be replaced from store out of sap. After GRN only one QM lot is generated. actually in that SFG one component got rejected. Now how should i replace this material??and how should i map it..here UD given as Rejected, which i think it is not correct because for one component we cant reject total assembly. we can replace that particular rejected component by disassembly. how to Replace that in assembly and how to make result recording for assembles.
