When I used MB11 to transfer a material from one storage location to a consignment contract (movement type: 413), an error appeared :Incorrect assignment of cost estimate number to the material key (Message no. C+451). I can not save this activity.
After test, there is one important clue: I think that material, plant and consignment contract are three important primary keys. Because, when I changed any one of these three primary keys to do this activity, material movement can be posted correctly.
I know that this problem is related to table CKMLHD, MBEW and KEKO. But, I don't know how to find the reason. Hope you can hele me. thanks a lot.
