SAP MRP Process with Alternate / Substitute Materials
We have a requirement in our Implementation process of Material Requirement Planning (MRP)
Here No Production Planning module is implemented.
Here Business has Spare parts materials in use in which they have below business requirement.
Main material (M) is declared as Spare part in system which may have multiple substitute materials also declared as spare parts in system.
Currently if say i have stock of main material M as 15 EA.
Substitute materials say A1, A2 & A3 with stocks as 05,00,15 EA.
If my requirement of material M is say 50 EA & when i do the MRP run, as per business requirement system should also consider the stock of substitute materials while doing calculations for requirement generation of material M
Deficit = Total Requirement - (Stock of M + Stock of A1 + Stock of A2 + Stock of A3)
= 50 - (15 + 05 + 00 + 15)
= 50 - 35
= 15 EA
For this deficit a Planned order or PR of 15 quantity should be generated only of Material M.
I require the expert guidance of you all for the requirement.
