Material Requirements Planning (MRP) – 9
This article is in continuation of the articles of the series “Material Requirements Planning (MRP) – 1”, “Material Requirements Planning (MRP) – 2“, Material Requirements Planning (MRP) – 3, and “Material Requirements Planning (MRP) – 4“, “Material Requirements Planning (MRP) – 5“, “Material Requirements Planning (MRP) – 6 “, “Material Requirements Planning (MRP) – 7 “ and “Material Requirements Planning (MRP) – 8 “
Source List
Explain the function of the source list. In doing so, outline the significance of the three indicators Fixed, Blocked, and MRP-relevant. Introduce the three options available for source list maintenance.
The source list is an aid in the administration of sources of a material for a plant. You specify which sources of a material are allowed and disallowed for a plant and the periods for which these two statuses are valid. Source list entries are taken into account in automatic source determination in purchasing and in requirements planning.

You can decide that a source is preferable over a certain period (Fixed indicator). If no procurement is to be allowed from a source of supply (or vendor) during a certain period, you set the Blocked indicator for the relevant source list entry.
In automatic requirements planning, a purchase requisition can be generated with a source of supply only if the source list for the material contains a valid entry with the MRP-relevant indicator set.
You can stipulate a source list requirement for a material. This means that this material may only be procured from sources that have been entered as valid in the source list. You will find the necessary indicator in the purchasing data of the material master record.
You can also specify the source list requirement for a plant (Customizing). However, this means that you must maintain source lists for all the externally procured materials of a plant.

The SAP R/3 System offers various procedures for source list maintenance.
- You can maintain the source list manually for each material and plant.
- When you create or change an outline agreement, you can adopt an outline agreement item in the source list for the material. To do so,
select the item and choose Item→ Maintain Source List. This is also possible when you create or change a purchasing info record. - You can also have a source list created automatically by the system.
The system provides the option of quickly entering or updating all the sources of a material in a source list. With this procedure, a source list record is created for each info record or outline agreement item. You can create the source list for several materials (collective procedure) or for an individual material (individual procedure). There is a preview function for the automatic generation of source lists. This allows you to simulate the effects of the source list generation run.
