  The SAP error message /MOC/INTEGRATION051 Call of RFC &1 in system &2 failed typically indicates that there was a failure when trying to call a Remote Function Call (RFC) in a specified system. This error can arise from various issues, including connectivity problems, authorization issues, or configuration errors.
  Causes:
  
  Network Issues: There may be network connectivity problems between the systems involved.

  Configuration Errors: The RFC destination may not be correctly configured in the SAP system.
  System Availability: The target system may be down or not reachable.
  Parameter Issues: Incorrect parameters being passed to the RFC function module.
  Version Mismatch: The RFC function may not be compatible between the two systems due to version differences.
  
  Solutions:
  
  
  Check Network Connectivity:
