Optimizing Production Planning
Considering Various Conditions 
Goal: orders or operations are to be dispatched so that existing conditions are met
Production planning often demands that existing conditions, such as material availability, capacity availability or order priorities, are taken into account.
One possible way you can optimize production planning is as follows:
...
1. Planning in the SAP system occurs, for example, using demand management, material requirements planning and/or master production scheduling.
2. Data exchange SAP system ® external system
– Selection of all required master
data
(materials, bills of material, routings, work centers, and so
on)
– Selection of all required
transaction data
(planned orders, current stock/requirements list, run schedule headers, and so
on)
3. Planning and optimization in the external system with the goal to take existing conditions into account:
– Dates for planned and production orders are set
– Production versions and routings for respective planned and production orders are determined
– Planned and production orders can be created or deleted
– Operation dates are reset
– Work centers for operations are specified
4. Data exchange external system ® SAP system
– Order start date and/or production version (and routings) of affected planned and production orders are changed in the SAP system
– Planned and production orders can be created or deleted
– Operation dates are reset
