Typically, purchase requisitions for stock material are generated automatically during the MRP run. In this process, the system calculates the required procurement quantities (based on requirement quantity or lot size) and determines the appropriate delivery dates. If available, the MRP run also identifies a suitable source of supply.
For externally procured stock material (procurement type "F" in the material master record), the following sources of supply may be considered:
- Info record
- Contract
- Scheduling agreement
If multiple sources of supply exist for a material, the MRP run selects the most suitable one based on the following priority:
- Scheduling agreement
- Contract
- Info record with the Automatic Sourcing indicator
This default source determination logic can be overridden by using source lists or quota arrangements. In such cases, quota arrangements take precedence over source lists.
