• What is the cause and solution for SAP error message S_LMCFG_CLM023 - PSE &1 &2 has different serial numbers ?

  The SAP error message S_LMCFG_CLM023 indicates that there is a mismatch in the serial numbers of the PSE (Personal Security Environment) files. This typically occurs when the system is trying to use a PSE that has been incorrectly configured or when there are multiple PSEs with different serial numbers that are being referenced.
  Cause:
  
  Multiple PSEs: The system may have multiple PSEs for the same purpose (e.g., SSL, client authentication) that have different serial numbers.
  Corrupted PSE: The PSE file may be corrupted or improperly generated.
  Configuration Issues: There may be configuration issues in the SAP system that lead to the system referencing the wrong PSE.
  
  Solution:
  
  Check PSE Files: Verify the PSE files being used in the system. You can do this using transaction code STRUST. Ensure that the PSEs are correctly configured and that there are no duplicates.
  Delete and Recreate PSE: If you find that the PSE is corrupted or incorrectly configured, you may need to delete the existing PSE and recreate it. This can be done in the STRUST transaction.
  Consistency Check: Ensure that all systems in a landscape (e.g., Development, Quality, Production) are using the same PSE configuration if they are supposed to communicate with each other.
  Update Configuration: If the PSE is being referenced in a specific configuration (like SSL or SSO), ensure that the configuration points to the correct PSE.
  Check for Transport Issues: If the PSE was transported from another system, ensure that the transport was successful and that the PSE is valid in the target system.
