• What is the cause and solution for SAP error message ESH_ADAPT_MSG031 - --> User account/authorization (S_RFCACL) is missing in back-end system ?

  The SAP error message ESH_ADAPT_MSG031 indicates that there is an issue with user account authorization, specifically related to the authorization object S_RFCACL in the back-end system. This error typically occurs when a user does not have the necessary permissions to execute Remote Function Calls (RFC) in the SAP system.
  Cause:
  
  Missing Authorization: The user account does not have the required authorization for the object S_RFCACL. This object controls access to RFC calls and is essential for the user to perform certain actions in the system.
  User Role Assignment: The user may not be assigned the appropriate roles that include the necessary authorizations.
  Back-end System Configuration: There may be issues with the configuration of the back-end system that prevent the user from accessing the required functions.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU01 to check the user’s profile and roles.
  Verify if the user has the necessary roles assigned that include the S_RFCACL authorization.
  
  
  
  Assign Required Roles:
  
  If the user does not have the required roles, you will need to assign them. This can be done through transaction PFCG (Profile Generator).
  Ensure that the roles assigned to the user include the necessary authorizations for S_RFCACL.
  
  
  
  Modify Authorization Profiles:
  
  If the roles do not include the required authorizations, you may need to modify the authorization profiles to include S_RFCACL.
  Ensure that the profile includes the necessary values for the fields in the authorization object.
  
  
  
  Testing:
  
  After making changes, have the user log out and log back in to ensure that the new authorizations take effect.
  Test the functionality that was previously causing the error to confirm that the issue is resolved.
  
  
  
  Consult Security Team:
  
  If you are not authorized to make changes to user roles or authorizations, consult your SAP security team or administrator for assistance.
  
  
  
  Related Information:
  
  
  Authorization Object S_RFCACL: This object is used to control access to RFC calls. It typically includes fields such as:
  
  RFC Function Group: The function group for which access is being controlled.
  RFC Function Module: The specific function module that the user is trying to access.
  Activity: The type of activity (e.g., execute, change) that the user is allowed to perform.
  
  
  
  Transaction Codes:

  PFCG: Role Maintenance
  SU53: Display Authorization Check (to analyze authorization issues)
