We are doing GR against a sub-contracting purchase order. At the time of doing GR, the RM components of the material are being called. Out of the Raw Materials, 2 material are having deficit quantities at the sub contracting vendor location. For one material we are getting error message M7021 (Deficit of Stock w. vendor unr. 2,218.804 KG : XYZ1 O), which is working file. For the second material we are getting message LB031 (Of the required quantity of material XYZ2, 779.018 KG remain(s) open).
However, when we save the GR, system is not giving message LB031 again, and not giving error in material code XYZ2 at all.
