How To Fix CY720 - Order & operation &: Overlap conflict with successor &

SAP Error Message - Details

• Message type: E = Error

• Message class: CY - Capacity Requirements Planning

• Message number: 720

• Message text: Order & operation &: Overlap conflict with successor &

What causes this issue?

An operation is to be dispatched in such a way that it overlaps with
thefollowing one. However no overlapping has been planned for the
operations.

How to fix this error?

Reschedule one of the operations that is causing the conflict or
reschedule another commitment so as to increase the available capacity.

• What is the cause and solution for SAP error message CY720 - Order & operation &: Overlap conflict with successor & ?

  The SAP error message CY720 indicates an overlap conflict between operations in a production order. This typically occurs when the scheduling of operations in a routing overlaps in a way that is not allowed by the system's configuration or the defined production process. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Overlapping Operations: The error arises when the start and finish times of one operation overlap with those of its successor operation. This can happen if:
  
  The duration of the predecessor operation is not sufficient to complete before the successor operation starts.
  The scheduling parameters (like lead times) are not set correctly.
  There are manual changes to the operation times that create conflicts.
  
  
  
  Routing Configuration: The routing for the production order may not be configured to allow for overlapping operations, or the settings for the operations may not be compatible.
  
  
  Capacity Constraints: If there are capacity constraints on the work center, it may not be possible to schedule operations as intended.
  
  
  Solutions:
  
  
  Check Operation Times: Review the start and finish times of the operations in the production order. Ensure that the predecessor operation finishes before the successor operation starts.
  
  
  Adjust Scheduling Parameters: Modify the scheduling parameters in the routing or the production order to allow for proper sequencing of operations. This may include adjusting lead times or operation durations.
  
  
  Review Routing Configuration: Ensure that the routing is correctly set up to allow for the intended sequence of operations. If necessary, modify the routing to eliminate conflicts.
  
  
  Capacity Planning: Check the capacity of the work centers involved. If there are capacity constraints, consider adjusting the scheduling or adding additional resources.
  
  
  Use Alternative Scheduling: If the operations must overlap for some reason, consider using alternative scheduling techniques, such as using parallel processing if the work center allows it.
  
  
  Re-schedule the Order: If the above adjustments do not resolve the issue, you may need to re-schedule the entire production order to ensure that all operations are sequenced correctly.
  
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like CO02 (Change Production Order) to view and modify the production order details.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Documentation: Review SAP documentation on production order management and routing to understand the configuration settings that may affect operation scheduling.
  
  By addressing the underlying causes of the overlap conflict, you should be able to resolve the CY720 error and successfully schedule your production operations.
