• What is the cause and solution for SAP error message WRF_APC755 - Internal transportation chain changed / system recalculated the dateline ?

  SAP Error Message:
  WRF_APC755 – Internal transportation chain changed / system recalculated the dateline
  
  Cause
  This message typically occurs in SAP Advanced Planning and Optimization (APO) or Supply Chain Planning (SCP) environments, particularly during transportation planning or production planning runs. The system detects that the internal transportation chain (i.e., the sequence or timing of transportation legs between locations) has changed compared to the previous planning run or the original data.
  Because the transportation chain has changed, the system recalculates the dateline (the planned arrival or departure dates) to reflect the updated transportation times or sequences.
  Common causes include:
  
  Changes in transportation lanes or routes (e.g., new or deleted transportation lanes).
  Changes in transportation lead times or transit times.
  Manual or automatic adjustments in transportation scheduling.
  Master data changes affecting transportation (e.g., changes in location relationships, transportation mode, or transit times).
  System recalculation triggered by planning heuristics or optimization runs.
  
  
  Solution
  
  
  Review Transportation Master Data:
  
  Check transportation lanes, transit times, and transportation mode data
