• What is the cause and solution for SAP error message /SCWM/CHM018 - No authorization to perform action ?

  The SAP error message /SCWM/CHM018 No authorization to perform action typically indicates that the user does not have the necessary authorizations to perform a specific action within the SAP Extended Warehouse Management (EWM) module. This can occur in various scenarios, such as trying to execute a transaction, access a report, or perform a specific function that requires certain permissions.
  Cause:
  
  Missing Authorization Roles: The user may not have been assigned the appropriate roles that include the necessary authorizations for the action they are trying to perform.
  Authorization Object Restrictions: The authorization objects related to the action may have restrictions that the user does not meet.
  Profile Issues: The user profile may not be correctly configured to allow access to the required functions.
  Changes in Authorization: Recent changes in the authorization roles or profiles may have inadvertently removed necessary permissions.
  
  Solution:
  
  Check User Roles: Verify that the user has the correct roles assigned. This can be done by checking the user’s profile in transaction SU01 (User Maintenance).
  Review Authorization Objects: Use transaction SU53 immediately after encountering the error to see which authorization objects are missing. This will provide insight into what specific permissions are lacking.
  Adjust Authorizations: If you have the necessary administrative rights, you can adjust the user’s roles or create a new role that includes the required authorizations. This can be done in transaction PFCG (Role Maintenance).
  Consult with Security Team: If you do not have the necessary permissions to change roles or authorizations, contact your SAP security team or administrator to request the required access.
  Testing: After making changes, have the user log out and log back in to ensure that the new authorizations take effect.
  
  Related Information:
  
  Authorization Objects: Familiarize yourself with the relevant authorization objects for the actions in EWM. Common objects include S_TCODE (Transaction Codes), S_USER_AUTH (User Authorizations), and specific EWM-related objects.
  Documentation: Refer to SAP documentation or the SAP Help Portal for detailed information on authorization management in EWM.
  Audit Logs: Check audit logs for any changes made to user roles or authorizations that might have led to this issue.
  Training: Ensure that users are trained on the necessary processes and understand the importance of having the correct authorizations.
  
  By following these steps, you should be able to identify the cause of the authorization error and implement a solution to resolve it.
