• What is the cause and solution for SAP error message ESH_CUST008 - Only RFC destinations with connection type '&1' can be used ?

  The SAP error message ESH_CUST008 indicates that there is an issue with the RFC (Remote Function Call) destination configuration in your SAP system. Specifically, it states that only RFC destinations with a certain connection type can be used for the operation you are trying to perform.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Incorrect RFC Destination Type: The RFC destination you are trying to use is not of the required connection type. For example, if the operation requires a TCP/IP connection and you are using a different type (like a file or HTTP connection), this error will occur.
  Configuration Issues: The RFC destination may not be properly configured or may not exist in the system.
  Authorization Issues: The user executing the operation may not have the necessary authorizations to access the specified RFC destination.
  
  Solution:
  To resolve the ESH_CUST008 error, you can follow these steps:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 in your SAP system.

  Create or Modify RFC Destination:
  
  If the RFC destination does not exist or is incorrectly configured, you may need to create a new one or modify the existing one.
  Ensure that the connection type is set correctly according to the requirements of the operation.
  
  
  
  Test the RFC Connection:
  
  In transaction SM59, you can test the RFC connection to ensure it is working correctly. This will help identify any connectivity issues.
  
  
  
  Check User Authorizations:
  
  Ensure that the user executing the operation has the necessary authorizations to access the RFC destination. You may need to check the user's roles and authorizations in transaction SU01.
