• What is the cause and solution for SAP error message /SAPAPO/CTM1266 - Transportation lane from &1 to &2 has been selected already ?

  The SAP error message /SAPAPO/CTM1266 indicates that a transportation lane from one location to another has already been selected in the context of the SAP Advanced Planning and Optimization (APO) system, specifically within the Capacity Planning or Transportation Planning modules. This error typically arises during the planning process when the system detects that a transportation lane is already in use for a particular planning run or operation.
  Cause:
  
  Duplicate Selection: The transportation lane has already been assigned to another planning operation or transportation requirement.
  Planning Run Overlap: If multiple planning runs are executed simultaneously or in quick succession, they may attempt to select the same transportation lane.
  Configuration Issues: There may be configuration settings that prevent the selection of the same transportation lane for different planning scenarios.
  
  Solution:
  
  Check Existing Assignments: Review the existing transportation lanes and their assignments to ensure that the lane is not already in use. You can do this by checking the transportation lane settings in the SAP APO system.
  Adjust Planning Parameters: If you are running multiple planning runs, consider adjusting the parameters to avoid overlap. Ensure that each planning run is configured to use different transportation lanes if necessary.
  Review Planning Sequence: Ensure that the planning sequence is correctly set up and that the transportation lanes are not being selected inappropriately due to misconfiguration.
  Use Alternative Transportation Lanes: If the selected transportation lane is not available, consider using alternative lanes that can fulfill the transportation requirements.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on managing transportation lanes and resolving conflicts.
  
  Related Information:
