• What is the cause and solution for SAP error message CY703 - Order & operation & begins after start of a successor ?

  The SAP error message CY703 indicates that there is a scheduling issue with an order and its operations in the context of production planning and control. Specifically, the error message states that an operation is scheduled to start before the predecessor operation has finished, which violates the scheduling constraints.
  Cause:
  
  Incorrect Scheduling: The operation in question is scheduled to start before the completion of its predecessor operation. This can happen due to incorrect setup of the routing or production order.
  Lead Time Issues: If the lead times defined in the routing or production order are not set correctly, it can lead to operations being scheduled incorrectly.
  Capacity Constraints: If there are capacity constraints that are not taken into account, it may lead to operations being scheduled in a way that is not feasible.
  Manual Changes: Manual changes to the scheduling of operations can inadvertently create conflicts.
  
  Solution:
  
  Check Routing and Operations: Review the routing for the production order to ensure that the sequence of operations is correct and that the lead times are properly defined.
  Adjust Scheduling: If the operations are incorrectly scheduled, adjust the start and finish times of the operations to ensure that they follow the correct sequence.
  Review Capacity Planning: Ensure that the capacity planning is correctly set up and that there are no conflicts in the scheduling of resources.
  Use Scheduling Tools: Utilize SAP's scheduling tools to automatically adjust the operations based on the defined constraints and lead times.
  Re-schedule the Order: If necessary, re-schedule the entire production order to ensure that all operations are aligned correctly.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CO02 (Change Production Order) or CO03 (Display Production Order) to review and adjust the production order.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to scheduling and operations.
  Documentation: Refer to SAP documentation on production planning and control for best practices in setting up routings and scheduling operations.
  Training: Consider training for users involved in production planning to minimize scheduling errors in the future.
  
  By addressing the root cause of the scheduling conflict and ensuring that operations are sequenced correctly, you can resolve the CY703 error and prevent it from occurring in the future.
