• What is the cause and solution for SAP error message CY728 - Order & operation &: Minimum overlap with predecessor & not achieved ?

  The SAP error message CY728 ("Order & operation &: Minimum overlap with predecessor & not achieved") typically occurs in the context of production planning and scheduling within SAP's Advanced Planning and Optimization (APO) or Production Planning (PP) modules. This error indicates that the scheduling of an operation does not meet the required minimum overlap with its predecessor operation.
  
  Cause:
  
  
  Scheduling Constraints: The operation you are trying to schedule has a defined minimum overlap with its predecessor operation, which is not being met. This can happen if:
  
  The start time of the current operation is too far in the future compared to the end time of the predecessor operation.
  The duration of the predecessor operation is longer than expected, causing a scheduling conflict.
  
  
  
  Configuration Settings: The minimum overlap requirement may be set in the routing or in the production version for the material. If the overlap is not configured correctly, it can lead to this error.
