The planning file controls which materials are to be planned for the different types of planning run.
To display the planning file, select Planning file entry ® Display from the menu screen of material requirements planning.
The planning file contains all materials that should be included in the planning run. The system enters materials automatically into the planning file and marks them with a total change indicator if a change is carried out which is relevant to the material, for example, changes to active purchase orders. If a change concerning the planning horizon occurs (for example, creating a purchase order within the planning horizon), the material is automatically given another indicator, that is, the net change planning indicator.
During the planning run, the system now checks every entry for a material in the planning file:
- for regenerative planning it plans all materials which are contained in the planning file without taking the indicators into account
- for net change planning, it only plans those materials which are provided with the total change indicator
- for net change planning in the planning horizon it only plans those materials provided with the net change planning indicator
Once the planning run has been carried out, the appropriate indicator is automatically deleted in the planning file.
If a termination occurs when planning a material, the indicators for this material are left in the planning file so that the material is taken into account again in the next net change planning run.
Depending on the error, you can, however, manually delete the indicators in Customizing.
