• What is the cause and solution for SAP error message /SCMTMS/UI_MESSAGES331 - Cannot change user; page layout &1 used in transp. cockpit layout &2 ?

  The SAP error message /SCMTMS/UI_MESSAGES331 indicates that there is an issue with changing the user in the Transportation Management System (TMS) due to a conflict with the page layout being used in the Transportation Cockpit. This error typically arises when the user tries to switch to a different user while a specific page layout is in use.
  Cause:
  
  Page Layout Conflict: The error occurs when the current page layout (denoted as &1) is not compatible with the layout used in the Transportation Cockpit (denoted as &2). This can happen if the layout settings are user-specific or if there are restrictions on changing users while certain layouts are active.
  User Permissions: The user may not have the necessary permissions to change the layout or to switch users in the current context.
  Session State: The session may be in a state that does not allow for user changes, possibly due to ongoing transactions or processes.
  
  Solution:
  
  Check Page Layouts: Verify the page layouts being used. Ensure that the layout you are trying to switch to is compatible with the Transportation Cockpit. You may need to switch to a default or different layout that does not cause conflicts.
  Log Out and Log In: Sometimes, simply logging out of the system and logging back in can resolve session-related issues. This can reset the state and allow for user changes.
  User Permissions: Ensure that the user has the necessary permissions to change layouts and switch users. Check with your SAP administrator if there are any restrictions in place.
  Clear Cache: If applicable, clear the cache of the SAP GUI or web browser (if using a web-based interface) to ensure that there are no stale session data causing the issue.
  Consult Documentation: Refer to SAP documentation or notes related to the Transportation Management System for any specific guidelines or known issues regarding user changes and layout management.
