Planning Mode in the Initial Screen
Use
The planning mode (Planning mode indicator in the initial screen of the planning run) controls how the system is to deal with procurement proposals (planned orders, purchase requisitions, scheduling agreement lines) from the last planning run, which are not yet firmed, in the next planning run. Firmed procurement proposals remain unchanged.
The planning mode is set automatically in the planning file. However, you can overwrite it in the initial screen of each planning run.
By choosing the correct planning mode, you avoid planning materials twice and thereby optimize system performance.

The following options are available:
For more information on planning modes, refer to
Planning Mode.The planning mode set in the planning file for a material can be overruled by the planning mode in the initial screen of the planning run. The following applies to this: For planning a particular material the planning mode that has the highest numerical value takes priority. Planning mode 2 (re-explode BOM) thus takes priority over planning mode 1 (adapt planning data), planning mode 3 (delete and recreate planning data) takes priority over planning mode 1 (adapt planning data) and planning mode 2 (re-explode BOM).
It is usually sufficient to set planning mode 1 in the initial screen of the planning run. If you have to plan a material with another planning mode, the system then sets the corresponding planning file entry in the planning file. The system evaluates this in the planning run.
It is important to set the planning run to planning mode 2 or 3 in the initial screen if changes have been made in Customizing or the routing, because no planning file entries are created automatically for the materials affected by these changes.
