• What is the cause and solution for SAP error message /SCMTMS/PLN_OPT_EXP509 - Stop fixed for optimization; one location visited at least twice ?

  The SAP error message /SCMTMS/PLN_OPT_EXP509 indicates that during the optimization process in SAP Transportation Management (TM), the system has detected that at least one location is being visited more than once in a single transportation planning run. This situation can arise in various scenarios, such as when multiple deliveries are being consolidated into a single transportation unit, or when the planning logic does not allow for the same location to be visited multiple times in a single route.
  Cause:
  
  Multiple Visits to the Same Location: The primary cause of this error is that the optimization algorithm has determined that a location (e.g., a customer or a distribution center) is scheduled to be visited more than once in the same planning run.
  Planning Constraints: There may be constraints set in the planning profile that prevent visiting the same location multiple times.
  Data Issues: Incorrect or incomplete master data (e.g., delivery data, location data) can lead to unexpected behavior during optimization.
  
  Solution:
  
  Review Planning Parameters: Check the planning parameters and constraints set in the transportation planning profile. Ensure that the settings allow for multiple visits if that is the intended behavior.
  Adjust Delivery Grouping: If the intention is to visit the same location multiple times, consider adjusting the delivery grouping or the way deliveries are consolidated into transportation units.
  Modify Route Optimization Logic: If the optimization logic is too strict, you may need to modify it to allow for multiple visits to the same location.
  Check Master Data: Ensure that all relevant master data (e.g., locations, transportation lanes, delivery data) is accurate and complete. Inconsistencies in data can lead to planning issues.
  Use Alternative Planning Strategies: If the current optimization strategy does not meet your needs, consider using alternative planning strategies or algorithms that can accommodate multiple visits to the same location.
  
  Related Information:
  
  SAP Notes and Documentation: Check SAP Notes related to transportation management and optimization for any known issues or updates that might address this error.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SCMTMS/PLN for planning and /SCMTMS/OPT for optimization settings.
  Community Forums: Engage with SAP community forums or user groups to see if others have encountered and resolved similar issues.
  Testing: Conduct tests with different planning scenarios to identify the specific conditions that trigger this error, which can help in finding a tailored solution.
  
  By addressing the underlying causes and adjusting the planning parameters, you should be able to resolve the error and successfully complete the optimization process in SAP TM.
