• What is the cause and solution for SAP error message LTR_PRESEL018 - Overflow of preselection step counter ?

  The SAP error message LTR_PRESEL018: Overflow of preselection step counter typically occurs in the context of the SAP Logistics Execution (LE) module, particularly when dealing with the preselection of delivery items or during the processing of deliveries. This error indicates that the system has exceeded the maximum number of preselection steps allowed during the processing of a delivery or related logistics operation.
  Cause:
  The primary cause of this error is usually related to the configuration or the data being processed. Specifically, it can occur due to:
  
  Excessive Preselection Steps: The system has a limit on the number of preselection steps it can handle. If the number of steps exceeds this limit, the overflow error is triggered.
  Data Volume: Large volumes of data being processed in a single operation can lead to this error, especially if there are many items or complex conditions involved.
  Configuration Issues: Incorrect or suboptimal configuration settings in the logistics execution or delivery processing can lead to inefficient preselection processes.

  To resolve the LTR_PRESEL018 error, consider the following steps:
  
  
  Review Preselection Configuration: Check the configuration settings related to preselection in the SAP system. Ensure that they are optimized for your business processes and that they do not lead to excessive preselection steps.
  
  
  Limit Data Volume: If possible, try to limit the number of items being processed in a single delivery or operation. This can help reduce the number of preselection steps required.
  
  
  Batch Processing: If you are processing a large number of deliveries or items, consider breaking them into smaller batches to avoid hitting the preselection step limit.
  
  
  Check for Custom Code: If there are any custom enhancements or user exits that modify the preselection logic, review them to ensure they are not causing unnecessary steps to be added.
  
  
  SAP Notes and Support: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates that can help resolve the issue.
