• What is the cause and solution for SAP error message WZ101 - RFC destination &1 could not be saved ?

  SAP Error Message:
  
  WZ101 RFC destination &1 could not be saved
  
  Cause:
  This error occurs when you try to save an RFC (Remote Function Call) destination in SAP, but the system is unable to save the entry. The placeholder &1 is replaced by the name of the RFC destination you attempted to save.
  Common causes include:
  
  
  Authorization Issues:
  
  The user does not have sufficient authorization to create or change RFC destinations.
  
  
  Incorrect or Missing Parameters:
  
  Mandatory fields in the RFC destination configuration are missing or incorrectly filled.
  
  
  Transport or Lock Issues:
  
  The RFC destination object might be locked by another user or transport request issues prevent saving.
  
  
  System or Database Issues:
  
  Underlying system problems such as database locks, inconsistencies, or system errors.
  
  
  Incorrect RFC Type or Configuration:
  
  The RFC destination type (e.g., TCP/IP, ABAP connection) is not properly configured or supported.
  
  
  
  Solution:
  
  
  Check Authorizations:  
  
  Ensure the user has the necessary authorization objects, such as S_RFC and S_RFCACL, to create or change RFC destinations.
  Use transaction SU53 immediately after the error to check for missing authorizations.
  
  
  
  Verify RFC Destination Parameters:  
  
  Go to transaction SM59 and review the RFC destination parameters.
  Ensure all mandatory fields are filled correctly (e.g., target host, system number, gateway, program ID).
  Check the connection type is appropriate for your scenario.
  
  
  
  Check for Locks or Transport Issues:  
  
  Use transaction SM12 to check if the RFC destination is locked by another user.
  If the RFC destination is transportable, ensure the transport request is properly assigned and not locked.
  
  
  
  Test the RFC Destination:  
  
  In SM59, use the "Test Connection" button to verify connectivity.
  If the test fails, investigate network or system issues.
  
  
  
  Check System Logs:  
  
  Use transaction SM21 to check system logs for related errors.
  Review short dumps in ST22 for any runtime errors related to RFC destination saving.
  
  
  
  SAP Notes and Support:  
  
  Search SAP Support Portal for notes related to WZ101 or RFC destination saving issues.
  Apply any relevant SAP Notes or patches.

  SAP Notes:
  
  Check for SAP Notes related to RFC destination errors, e.g., notes about authorization or transport issues.
  
  
  RFC Destination Types:  
  
  Type 3: ABAP Connection

  Common RFC Destination Issues:  
  
  Incorrect gateway host or program ID  
  Network connectivity problems  
  Missing or incorrect user credentials
  
  
  
  
  If after these checks the problem persists, consider raising a support ticket with SAP, providing detailed information about the RFC destination configuration, user authorizations, and system logs.
