 Sub-Operation Dates Locate this document in the navigation structure

Sub-operations are not divided into individual operation segments in scheduling. The system schedules start and finish dates for the sub-operations from their reference dates.

To define the start and the finish of a sub-operation, you must maintain the following data on the Operation Details screen:

  • a reference date (for example, start of setup or finish of the execution of the corresponding operation)

  • an offset

  • If the offset is positive, forward scheduling is carried out starting from the reference date.

  • If the offset is negative, backward scheduling is carried out starting from the reference date.

Note Note

If you have not maintained scheduling data for a sub-operation, the start date of setup and the finish date of execution are transferred to the sub-operation.

End of the note.
