  The SAP error message RSCRM235 indicates that there is an issue with the Remote Function Call (RFC) connection in your SAP system.

This can occur in various scenarios, such as when trying to execute a remote function module or when setting up a connection to another SAP system or external system.
  Cause:
  The primary cause of this error is that the RFC destination (connection) you are trying to use does not have a valid user ID specified. This can happen if:
  
  The RFC destination was not configured correctly.
  The user ID was removed or not set up in the destination.
  The connection is set to use a specific user, but that user is not defined.
  
  Solution:
  To resolve the RSCRM235 error, follow these steps:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction code SM59 in your SAP system.

  Double-click on the RFC destination to open its configuration.
  
  
  
  Specify a User:

  Ensure that a valid user ID is specified in the "User" field.
  If necessary, enter the password for the user in the "Password" field.
  
  
  
  Test the Connection:
  
  After specifying the user, use the "Connection Test" button to verify that the RFC connection works correctly.
  If the test is successful, save your changes.
  
  
  
  Check Authorizations:
  
  Ensure that the specified user has the necessary authorizations to perform the required actions on the target system.
  
  
  
  Review Related Settings:
