Customer directed parts issue
In one of our running implementations we have the following requirement.
We have A material a which the plant procures from vendor G and H that material a is used in let's say 2 finished goods X and Y. The customer for finished good X informs us that in his product material A needs to be procured from vendor H whereas customer Y does not impose this rule onto us.
So how does the ERP system react to this?
We receive the following orders from our customer:
Customer for finished good X orders 200 pcs
Customer for finished good Y orders 100 pcs
These requirements are entered into SAP and we then run to MRP.
The result of MRP will be a requirement for component A of 300 pcs.
If we use a source list together with a quota arrangement (quota split 50% to vendor G and 50% to vendor H), purchasing will order the following quantities of material A at vendor H and G:
H : 150 pcs
G : 150 pcs
This means that when we produce finished good X we have not enough components that are received from the customer directed vendor which will cause problems.
Typically having 2 different part numbers for the same material would solve this issue. However the engineering department says that if a material is the same in fit-form or function it can only have 1 material number.
Is there a way in purchasing that we can split these requirements so that the orders for the customer directed material go to the correct vendor?
