Hai Sappers, this is a typical situation I am facing. Ours is an auto industry & we have materials that are alternatives to other materials. These materials are perfect substitutes of each other & are known as alternatives. (the user can consume either of the materials or both). How to maintain the relation between the alternatives in SAP? How the MRP considers the quantity of each alternative for the MRP calculation?
You can have 2 options:
1) Create only one generic material in your system and while placing orders for different equivalent materials, mention the equivalent product name in the vendor info record Under vendor prwhich will get copied to Purchase order. Thus in your system you will have only one material.
2) If this is not suitable for you, than you can configure Manufacturer Part Number functionality.
Option No 1 . Pl take this scenario of a Chemical co.
Step 1 - Creation of Material in SAP
In this case, you will create material in SAP as Silicon Surfactant. This material will be used in BOM.
You will not create 3 different alt.materials like Material 1,2 and 3 in system.
Step 2 - Vendor Inforecord will have Vendor Material No i.e Material 1 etc.
Thus whenever you will print PO, PO will be printed with reference to your internal SAP material no i.e of Silicon Surfactant and will also have vendor material no. If you want only Vendor material to be printed then you have change the print format.
Thus for MRP, only 1 material will be cionsidered. Hope this is clear.
Option No2 -Manufacturer's Part Number
Step 2 -
Step 5 - Do a GRN
MPN process works like this :
