Use this session to view the constraints encountered by the Scheduling Engine.
Field Information
- Scenario
- The code of the scenario.
- Scheduling Constraint ID
- The ID of the scheduling constraint.
- Production Order
- The code of the production order for which the scheduling constraint is defined.
- Operation Block
- The code of the operation block.
- Resource Type
-
The type of resource used for the production order operation.
Allowed values
- Not Applicable
- Machine
- Employee
- Tool
- Site
- The code of the site linked to the production order.
- Work Center
- The code of the work center linked to the production order.
- Machine Type
- The code of the machine capacity group.
- Machine
- The code of the machine required for the order.
- Employee
- The user name of the employee.
- Tool
- The code of the tool required for the order.
- Tool Number
- A unique number assigned to the tool.
- Item
- The code of the item to be produced.
- Previous Operation
- The code of the previous operation performed for the specific scenario.
- Constraint Type
-
The type of constraint encountered during scheduling.
Allowed values
- Machine
- Work cannot be performed because the required machine is not available.
- Employee
- Work cannot be performed because the concerned employee is not available.
- Tool
- Work cannot be performed because the tool that is required is not available.
- Predecessor
- Work cannot be performed because one of the production operation order step's predecessor is not completed.
- Subassembly
- Work cannot be performed because the required subassembly is not available.
- Delayed/Postponed Statuses
- Work cannot be performed because the production operation order status is set to Delayed or Postponed and the order cannot start.
- Purchased Item
- Work cannot be performed because the necessary raw material is not available.
- Perish between Operations
- Work cannot be performed because the maximum perishability value in of an operation is exceeded.
- Perish within Operation
- Work cannot be performed because the maximum perishability value between indivisible operations is exceeded.
- Fixed Buffer
-
Work could not start when it is scheduled because of the value of the parameter:
- SCH_DynBufDefault
- Dynamic Buffer
- Work cannot be performed because of the value of the dynamic buffer specified for the machine.
- Transfer Time
- Work cannot be performed because of the transfer time specified for the operation for which the operation order step is generated. Transfer time is the time taken to transfer to the next operation.
- Raw Material
- Work cannot be performed because the necessary raw material is not available.
- Start Date
- Delay
- Delay Unit

Allowed values
