There are several ways to create a sourcing list in SAP :
1, ME01 manually created individually.
2, ME05 system automatic batch creation.
3. Created by the menu "attach"-"source list" in the information record.
4, through the purchase contract in the menu "project"-"maintain the source list" created.
5. Create through the menu "project"-"Maintain source list" in the plan agreement.
In addition, there is no material number of the material can also build a source list, but not by the ME01 to establish, but through the purchase contract to build, and then there will be "exclude the identification", you can be the same item group of some material number excluded. Of course, the "exclusion of identity" selection can be set according to the actual situation.
