Hi,
I have configured the Manufacturer part profile in our system and MPN is kept as mandatory so that user must select only MPN for ordering purpose, we have maintain source list for our internal material codes and we required that same list to be refer for all MPN which are attach to that internal number, is there any setting for this, as while creating the MPN material only purchasing and purchase order text view appear in the MM01 after that when I am trying to make source list with ME01 for MPN part code system is giving message MPN material is not create for Plant XXXX, and in MP01 if I assign vendor code along with MPN then also system is allowing to create PO to another vendors which are not present in ME01 for internal materials and also in MP01 for MPN materials.
regards,
zafar
