Production planning heuristics create planned orders or purchase requirements.<br />

In these heuristics the planning algorithm and its parameters are<br />

defined.<br />

In the PP/DS module heuristics are available for different objectives as<br />

scheduling, fixing the pegging and more. To see whether a heuristic is<br />

suited for production planning the properties of the heuristic can be<br />

checked in the table /SAP<strong>APO</strong>/HEURFUNC. For production planning heuristics<br />

the field PROD_HEUR contains an entry. The PP/DS heuristics are<br />

displayed and maintained <strong>with</strong> the transaction /SAP<strong>APO</strong>/CDPSC11.<br />

The standard algorithm set by default in the global parameters for<br />

production planning is /SAP<strong>APO</strong>/HEU_PLAN_STANDARDLOTS, which is<br />

used in the standard heuristic SAP_PP_002. Production planning consists of<br />

the steps<br />

1. net requirements calculation<br />

2. procurement quantity calculation and<br />

3. source determination.
