• What is the cause and solution for SAP error message LF036 - User &1 is already active in another warehouse number ?

  The SAP error message LF036 indicates that a user is already active in another warehouse number. This typically occurs in the context of warehouse management (WM) when a user attempts to log into a different warehouse while they are still logged into another one.
  Cause:
  
  User Session: The user is already logged into a different warehouse number, which prevents them from logging into a new one.
  Session Management: SAP restricts users from being active in multiple warehouse numbers simultaneously to maintain data integrity and avoid conflicts.
  Configuration Issues: There may be configuration settings in the warehouse management system that enforce this restriction.
  
  Solution:
  
  Log Out: The user should log out of the current warehouse session before attempting to log into a new warehouse. This can usually be done through the SAP GUI or the relevant transaction code.
  Check Active Sessions: If the user is unsure where they are logged in, they can check their active sessions or ask an administrator to help identify and terminate any active sessions.
  Use Different User: If the user needs to work in multiple warehouses simultaneously, consider using a different user account for each warehouse.
  System Configuration: If this behavior is not desired, consult with your SAP Basis or WM administrator to review the system configuration and see if adjustments can be made to allow multiple active sessions.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as LX01 (Warehouse Management Monitor) or LT01 (Transfer Order Creation) to manage warehouse activities.
  User Management: Administrators can use transaction SU01 to manage user sessions and check active logins.
  SAP Notes: Check SAP Notes for any updates or patches related to warehouse management and user session handling.
