Fixing Objects for Optimization
Use
Activities, operations, and orders can be fixed during optimization ; that is, the system cannot reschedule them. If time relationships or pegging relationships exist between fixed objects and non-fixed objects, the system can only reschedule the non-fixed objects such that these relationships or pegging relationships are not violated.
The following objects are fixed for optimization:
Activities that do not lie, or only partially lie, within the optimization range
Started, partially confirmed or finally confirmed operations
Operations that you fixed in the production planning run or in the DS planning board
Sales orders
Planned independent requirements
Activities that start or end within a fixing intervalfor a resource
Activities that belong to the same locked activity chainas the activities that are fixed for optimization
You can fix the following objects for the optimization as required:
Selected order categories (for example, in-house production orders or external procurement orders)
Orders that only lie partially in the optimization range
Released orders
Orders that contain started, partially confirmed, or finally confirmed operations
Orders that contain activities that are already fixed for optimization
Scheduled operations, if you have specified in the optimization profile that only deallocated orders should be scheduled by the optimization
You enter the corresponding settings when calling up the optimization, or in the optimization profile on the
Order processing
tab page.
