How To Fix CY347 - Network &/&: The finish date is after the constraint date

SAP Error Message - Details

• Message type: E = Error

• Message class: CY - Capacity Requirements Planning

• Message number: 347

• Message text: Network &/&: The finish date is after the constraint date

What causes this issue?

The finish date for the operation has the constraint that it should not
finish after a particular date (constraint date). However the start
date when you want to dispatch the operation leads to a finish date
which is after the constraint date. Therefore it is not possible to
dispatch the operation.

How to fix this error?

You should change the start date so that the operation finishes before
the constraint date.

• What is the cause and solution for SAP error message CY347 - Network &/&: The finish date is after the constraint date ?

  The SAP error message CY347 ("Network &/&: The finish date is after the constraint date") typically occurs in project management or production planning scenarios when there is a scheduling conflict in a network or project. This error indicates that the finish date of a task or activity is set to occur after a defined constraint date, which is not allowed according to the scheduling rules in SAP.
  Cause:
  
  Constraint Date: A constraint date is a specific date that limits when a task can start or finish. This could be a "Must Finish On" or "Finish No Later Than" constraint.
  Scheduling Conflicts: The finish date of the task is calculated based on the dependencies and durations of preceding tasks, and it exceeds the constraint date set for that task.
  Incorrect Dates: The dates entered for the task or its dependencies may be incorrect or not aligned with the project timeline.
  Resource Availability: If resources are not available as planned, it may push the finish date beyond the constraint.
  
  Solution:
  
  Review Task Dates: Check the finish date of the task and ensure it is set correctly. Adjust the task duration or start date if necessary.
  Adjust Constraints: If the constraint date is too restrictive, consider adjusting it to allow for the calculated finish date of the task.
  Check Dependencies: Review the dependencies of the task to ensure that all preceding tasks are scheduled correctly and that their finish dates allow for the current task to start and finish on time.
  Resource Planning: Ensure that resources are available as planned. If there are resource constraints, consider reallocating resources or adjusting the project schedule.
  Re-schedule the Network: Use the scheduling functions in SAP to re-schedule the network and see if the error persists after making adjustments.

  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to scheduling and constraints.
  Documentation: Refer to SAP documentation on project management and network scheduling for more detailed guidance on handling constraints and scheduling errors.
  
  By following these steps, you should be able to resolve the CY347 error and ensure that your project scheduling aligns with the defined constraints.
