• What is the cause and solution for SAP error message S_LMCFG_CLM025 - PSE &1 &2 has different key length ?

  The SAP error message S_LMCFG_CLM025 indicates that there is a mismatch in the key length of the PSE (Personal Security Environment) files. This typically occurs when the system is trying to use a PSE that has a different key length than what is expected or configured in the system.
  Cause:
  
  Key Length Mismatch: The PSE files (usually related to SSL or cryptographic operations) have been generated with different key lengths. For example, one PSE might be using a 1024-bit key while another might be using a 2048-bit key.
  Configuration Issues: The system configuration may not be aligned with the PSE settings, leading to inconsistencies.
  Migration or Upgrade: If the system has been migrated or upgraded, the PSE files may not have been updated correctly, leading to this error.
  
  Solution:
  
  
  Check PSE Configuration:
  
  Use transaction STRUST to check the PSE settings. Ensure that the key lengths are consistent across the PSE files being used.
  If you have multiple PSEs (e.g., for different clients or systems), ensure they all have the same key length.
  
  
  
  Regenerate PSE:
  
  If you find that the key lengths are indeed different, you may need to regenerate the PSE with the correct key length. This can be done in the STRUST transaction by selecting the appropriate PSE and using the option to create a new PSE.
  Make sure to back up the existing PSE before making changes.
  
  
  
  Update Configuration:
  
  After regenerating the PSE, ensure that any related configurations (like SSL settings) are updated to reflect the new PSE.
  
  
  
  Check for System Notes:
  
  Sometimes, SAP releases notes that address specific issues. Check the SAP Support Portal for any relevant notes that might provide additional guidance or patches.
  
  
  
  Testing:
  
  After making changes, test the system to ensure that the error is resolved and that the PSE is functioning correctly.
  
  
  
  Related Information:
  
  PSE Types: There are different types of PSEs in SAP, such as the SSL PSE, the X.509 PSE, etc. Ensure you are working with the correct type for your use case.
  Key Length Standards: Be aware of the security standards and recommendations for key lengths, as they may change over time. For example, 2048-bit keys are generally recommended for SSL certificates.
  SAP Documentation: Refer to the official SAP documentation for detailed instructions on managing PSEs and troubleshooting related issues.
  
  If the problem persists after following these steps, consider reaching out to SAP support for further assistance.
