• What is the cause and solution for SAP error message CY748 - Order & operation &: Start date limit exceeded ?

  The SAP error message CY748 ("Order & operation &: Start date limit exceeded") typically occurs in the context of production planning and control, particularly when dealing with operations in a production order. This error indicates that the start date of an operation exceeds the allowed limits set in the system.
  Cause:
  
  
  Date Configuration: The start date of the operation is beyond the permissible limits defined in the system settings. This could be due to:
  
  The operation's scheduled start date being set too far in the future.
  The configuration of the planning parameters that restrict the scheduling of operations.
  
  
  
  Capacity Constraints: If there are capacity constraints or resource availability issues, the system may not be able to schedule the operation within the defined limits.
  
  
  Order Status: The status of the production order may not allow for scheduling or rescheduling of operations.
  
  
  Master Data Issues: Incorrect or incomplete master data for the materials, resources, or production versions can lead to scheduling issues.
  
  
  Solution:
  
  
  Check Operation Dates: Review the scheduled start date of the operation in the production order. Ensure that it falls within the acceptable range defined in the system.
  
  
  Adjust Planning Parameters: If necessary, adjust the planning parameters in the configuration settings to allow for a wider range of scheduling dates.
  
  
  Review Capacity Planning: Check the capacity planning settings and ensure that the resources required for the operation are available during the scheduled time.
  
  
  Change Order Status: If the order status is preventing scheduling, consider changing the status to allow for the necessary adjustments.
