This IWX Mx Mcn. Alt. Constraints page allows you to define secondary constraints that depend on the specific work center or machine center an operation is scheduled on. Depending on how you have set up the machine alternate groups, this can be specific to the work center or machine center, an item and an operation schedule on, or a specific production order and operation on the defined work center or machine center.

These constraints are used when machine- and operation-specific tooling or highly skilled operators are required and cannot be defined at a higher level, such as the production order components. If the constraint is generic and applies whenever the work center or machine center is running, define the constraint on the Resource Requirements page. If the constraint applies based on the operation and is not specific to the work center and machine center, define the constraint in the production bill of materials.
