• What is the cause and solution for SAP error message SUSR_CERT131 - Select only one explicit mapping ?

  The SAP error message SUSR_CERT131 indicates that there is an issue with the configuration of user mappings in the SAP system, specifically related to the use of multiple mappings for a single user. This error typically arises in the context of Single Sign-On (SSO) or when dealing with user authentication and authorization.
  Cause:
  The error occurs when the system detects that there are multiple explicit mappings defined for a user, which leads to ambiguity in determining which mapping to use. This can happen in scenarios where:
  
  There are multiple entries in the user mapping table for the same user.
  The configuration for user authentication is not set up correctly, leading to conflicting mappings.
  The system is trying to resolve a user identity but finds more than one valid mapping.
  
  Solution:
  To resolve the SUSR_CERT131 error, you can follow these steps:
  
  
  Check User Mappings:

  Remove Duplicate Mappings:

  Review Configuration:
  
  Check the configuration settings for your SSO or user authentication method. Ensure that the mappings are correctly defined and that there are no conflicting entries.
  
  
  
  Test the Changes:
