Hi Experts
I am working on a scenario wherein I am confused with using alternate or substitute fucntionality for Materials in SAP ECC.
Scenario:
The alternate materials are created for material in ECC.For eg
Primary material - MAT. A
1st Alternate material for MAT A = MAT B
2nd Alternate material for MAT A = MAT C
During MRP run, the alternate material is chosen by MRP controller if the stock for primary material is insufficient. Then the controller assigns(manually) this alternate material for the orders wherein the primary material MAT A is used.
Now this material is pushed to MES (a SAP MES software) and there in too the plant planner or manager can change the assignment of alternate material. For eg...Can change MAT B with another alternate MAT C. This means BOM undergoes a revision.
My question is how can it be managed in ECC? Since the master data is governed by ECC, how does the change happening in MES can be traced in ECC? Is this functionality called alternate material or substitute material in ECC?
Help resolve this understanding/solution. Thanks.
