• What is the cause and solution for SAP error message WRF_APC727 - Transportation chains don't match / system recalculated the dateline ?

  SAP Error Message:
  
  WRF_APC727 – Transportation chains don't match / system recalculated the dateline
  
  Cause
  This error occurs in SAP Advanced Planning and Optimization (APO), specifically in the Supply Network Planning (SNP) or Transportation Planning/Vehicle Scheduling (TP/VS) modules, when there is a mismatch between the transportation chains defined in the system and the actual transportation chains used or expected during planning or order processing.
  More specifically:
  
  The system detects that the transportation chain assigned to a product/location combination or transportation lane does not match the transportation chain used in the current planning run or order.
  This mismatch leads to inconsistencies in the calculation of transportation lead times and datelines.
  As a result, the system recalculates the dateline (the date by which goods must be shipped or received) based on the transportation chain it considers valid, which differs from the originally assigned chain.
  
  Common scenarios causing this:
  
  Changes in transportation lanes or transportation chains without proper synchronization.
  Master data inconsistencies between transportation lanes, product/location assignments, and planning objects.
  Manual changes or incorrect assignment of transportation chains in the system.
  Transportation chains not maintained or incomplete in the system.
  
  
  Solution
  
  
  Check Transportation Chain Assignments:
  
  Verify the transportation chains assigned to the relevant transportation lanes.
  Use transaction /SAPAPO/TSCHAIN to display and maintain transportation chains.
  Ensure that the transportation chain assigned to the product/location or transportation lane matches the one expected by the system.
  
  
  
  Synchronize Master Data:
  
  Check the consistency of master data between transportation lanes, product/location assignments, and transportation chains.
  If changes were made recently, ensure that all related objects are updated accordingly.
  
  
  
  Review Planning Objects:
  
  Check the planning objects (e.g., SNP orders, transportation lanes) involved in the error.
  Confirm that the transportation chain used during planning matches the master data.
  
  
  
  Recalculate or Adjust Datelines:
  
  If the system recalculated the dateline, verify if the new dateline is correct.
  If necessary, adjust the transportation chain or lead times to align with business requirements.
  
  
  
  Transport Chain Maintenance:
  
  If transportation chains are missing or incomplete, create or complete them.
  Ensure that all relevant transportation lanes have valid transportation chains assigned.
  
  
  
  Check for Notes or Patches:
  
  Review SAP Notes related to transportation chains and dateline recalculations for your SAP APO version.
  Apply any relevant patches or corrections.

  Summary
  The error WRF_APC727 indicates a mismatch between transportation chains in the system and those used during planning, causing the system to recalculate datelines. The solution involves verifying and synchronizing transportation chain assignments, ensuring master data consistency, and adjusting transportation lanes or lead times as needed. Proper maintenance of transportation chains and lanes is essential to avoid this error.
