Approved Manufacturer Parts List (AMPL)
If you wish to check and control which MPN materials may be procured, you should make use of the approved manufacturer parts list (AMPL).
In this list, you can specify for each MPN material
- Whether it can be procured for a certain plant only or for all the plants of your enterprise
- The period during which the MPN material may be procured
- Whether it must belong to a certain revision level
- Whether it may only be procured from a certain manufacturer plant
- Whether it is blocked and, if so, why
You can define reasons for blocking MPN materials in Customizing for Purchasing under Material master.
You should define a Manufacturer part profile under Material master in Customizing for Purchasing. Set the indicator for AMPL management so that the system checks the approved manufacturer parts list when the MPN material is entered.
Enter the manufacturer part profile in the master record of the inventory-managed material (Purchasing view).
In order that the system checks whether the manufacturer plant entered is allowed, you must
Create master records with the account group MNFR for the manufacturer plants;
Enter the manufacturer plants with the partner role HS in the manufacturer or vendor master record;
Specify a checking rule in the manufacturer part profile.
You maintain the approved manufacturer parts list via the Purchasing menu under Master data ® Appr. manuf. parts
At this point, SAP provides the enhancement AMPL0001, enabling you to define your own criteria for the admissibility of manufacturer parts.
