• What is the cause and solution for SAP error message /SCWM/UI_SERVICES002 - Warehouse number is not unique ?

  The SAP error message /SCWM/UI_SERVICES002 Warehouse number is not unique typically occurs in the SAP Extended Warehouse Management (EWM) module when there is an attempt to access or manipulate a warehouse number that is not uniquely identifiable in the system. This can happen for several reasons, and understanding the cause is essential for finding a solution.
  Causes:
