• What is the cause and solution for SAP error message LTR2_BASIS_CHECK645 - Parameter &1 is specified as RCV-logsys. The value &2 is not necessary. ?

  The SAP error message LTR2_BASIS_CHECK645 indicates that there is an issue with the configuration of the logical system in the context of the SAP Landscape Transformation (SLT) replication setup. Specifically, the error states that a parameter (in this case, RCV-logsys) has been specified, but the value provided is not necessary or valid.
  Cause:
  
  Incorrect Configuration: The logical system specified in the parameter RCV-logsys may not be required for the operation you are trying to perform. This could happen if the system is misconfigured or if the logical system is not set up correctly in the SLT configuration.
  Redundant Parameter: The parameter might be redundant in the context of the current operation, meaning that it is not needed for the replication setup you are trying to establish.
  Version Mismatch: There could be a version mismatch between the SLT system and the source or target systems, leading to unexpected behavior.
  
  Solution:
  
  Check Configuration: Review the SLT configuration settings to ensure that the logical system is correctly defined. You can do this by navigating to the SLT configuration transaction (usually LTRC or LTRS) and checking the settings for the relevant replication setup.
  Remove Redundant Parameter: If the parameter RCV-logsys is indeed not necessary, you can remove it from the configuration. This can typically be done in the SLT configuration screen where you define the replication settings.
  Validate Logical Systems: Ensure that the logical systems involved in the replication (both source and target) are correctly defined in transaction SALE (for logical system configuration) and that they are active.
  Check Documentation: Refer to the SAP documentation for SLT to understand the required parameters for your specific scenario and ensure that you are not missing any critical configuration steps.
  Consult SAP Notes: Check for any relevant SAP Notes that might address this specific error message or provide additional guidance on configuration best practices.
