  SAP Error Message:
  WT237 - Error while starting RFC: Different PBT groups cannot be initialized
  
  Cause
  This error occurs in SAP Warehouse Management (WM) when trying to start an RFC (Remote Function Call) session related to the PBT (Process-Oriented Storage Control) functionality. The message indicates that there is an attempt to initialize or start RFC calls for different PBT groups simultaneously, which is not allowed.
  PBT groups are used in process-oriented storage control to group storage bins or warehouse processes. The system expects that RFC calls related to PBT are handled per group, and mixing different groups in one RFC session leads to this error.
  Typical causes include:
  
  Configuration or customization issues where multiple PBT groups are incorrectly assigned or mixed in the same process.
  Incorrect or inconsistent data in the warehouse management master data or process-oriented storage control settings.
  Programming or user errors where the RFC call is triggered with parameters that span multiple PBT groups.
