• What is the cause and solution for SAP error message /SAPAPO/PDRP_APPR123 - Transportation lane referenced in source of supply &1 not found ?

  The SAP error message /SAPAPO/PDRP_APPR123 indicates that there is a problem with the transportation lane configuration in the Advanced Planning and Optimization (APO) module. Specifically, the error states that a transportation lane referenced in the source of supply is not found. This can occur during planning runs or when trying to execute certain functions in APO.
  Cause:
  
  Missing Transportation Lane: The transportation lane that is supposed to connect the source of supply (e.g., a vendor or production location) to the destination (e.g., a distribution center or customer) is not defined in the system.
  Incorrect Configuration: The transportation lane may have been incorrectly configured or deleted.
  Data Inconsistency: There may be inconsistencies in the master data, such as the source of supply not being properly set up or activated.
  Transport Lane Validity: The transportation lane may not be valid for the planning period being considered.
  
  Solution:
  
  
  Check Transportation Lane Configuration:
  
  Go to the transaction code /SAPAPO/TPVS (Transportation Lane Maintenance) in SAP APO.
  Verify if the transportation lane exists for the specified source of supply and destination.
  If it does not exist, create a new transportation lane with the correct parameters.
  
  
  
  Review Source of Supply:
  
  Ensure that the source of supply (e.g., vendor, plant) is correctly defined and active in the system.
  Check if the source of supply is assigned to the correct transportation lane.
  
  
  
  Validate Data:
  
  Check for any inconsistencies in the master data related to the transportation lane, source of supply, and destination.
  Ensure that all relevant master data (e.g., location, product) is correctly maintained.
  
  
  
  Check Validity Period:
  
  Ensure that the transportation lane is valid for the planning horizon you are working with. If the lane is only valid for a specific period, it may not be available for the current planning run.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to transportation lane configuration and troubleshooting for additional insights.
  
  
  
  Testing:
  
  After making the necessary changes, run the planning process again to see if the error persists.
