The Sourcing Rule determines whether to get the Item/Category from a specific Supplier, Supplier and Site or a transfer from an Organization. These rules are then assigned to an assignment set to associate them with an Item or Category:
1.Sourcing Rule Name.
2.The combination of the sourcing rule name and organization has to be unique. If the sourcing rule is for all organizations then the name is unique.
3.Effective Dates.
4.Buy From or Transfer.
5.Supplier or Supplier and Supplier Site.
Assignment Set
Once an assignment is made for a given sourcing rule and item, purchasing is then able to determine where to get that particular item from:
1.Assignment Set - This is seeded as ‘Supplier Scheduling’.
2.Assigned To - Is typically set to ‘Item’ for sourcing rules that are for all orgs, and ‘Item-Organization’ for inventory organization specific sourcing rules.
3.Item/Category - Specifies the item the assignment is for.
4.Type – ‘Sourcing Rule’.
5.Sourcing Rule/BoD – The Sourcing Rule name.
Profile Option “MRP: Default Sourcing Assignment set” - Determines which assignment set to use for the site. There is the option to enable this profile option at the responsibility level so it can be different for a given operating unit.
Approved Supplier List
The final part is to determine which document to use once the source is established for a given item. Approved Supplier Lists (ASLs) are defined by item and associated to a list of suppliers. For each supplier there are attributes that allow the ASL to be linked to a document (Quotation or Blanket Agreement).
Profile Option “PO: Automatic Document Sourcing” - This determines if the ASLs are used or if the most recent approved Blanket Agreement or active Quotation is leveraged for sourcing.
