SAP Error Message - Details

• Message type: E = Error

• Message class: RMXTDIA - TMS-DIA: Messages for Trial Interface

• Message number: 021

• Message text: RFC destination not found for logical system &1

What causes this issue?

The system cannot read the planning dates (start and end).
The data for the planned order and process order for the trial &V2& is
stored in the logical system &V1&. To enable the system to read this
data, you first have to define the RFC destination for the logical
system in Customizing.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Procedure for System Administrators

Make an entry for the logical system &V1& in Customizing. Ensure that
the connection type of the new RFC entry is <ZK>Connection to SAP System

• What is the cause and solution for SAP error message RMXTDIA021 - RFC destination not found for logical system &1 ?

  The SAP error message RMXTDIA021 indicates that the system is unable to find the specified RFC (Remote Function Call) destination for the logical system mentioned in the error message. This typically occurs in scenarios where there is an attempt to communicate with another SAP system or external system, and the required configuration for the RFC destination is missing or incorrect.
  Cause:
  
  Missing RFC Destination: The RFC destination for the specified logical system is not defined in the SAP system.
  Incorrect Configuration: The RFC destination exists but is not configured correctly (e.g., wrong connection parameters).
  Logical System Not Defined: The logical system itself may not be defined in the system or may not be correctly assigned to the client.
  Authorization Issues: The user may not have the necessary authorizations to access the RFC destination.
  Network Issues: There may be network connectivity issues preventing access to the target system.
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 (RFC Destinations).
  Look for the RFC destination that corresponds to the logical system mentioned in the error message.
  If it does not exist, create a new RFC destination with the appropriate connection type (e.g., T, 3, etc.) and fill in the required parameters (like target host, system number, etc.).
  
  
  
  Verify Configuration:
  
  If the RFC destination exists, double-check the configuration settings (e.g., target host, service, user credentials).
  Test the connection using the "Connection Test" button in SM59 to ensure it is working correctly.
  
  
  
  Check Logical System Configuration:
  
  Go to transaction SALE or SPRO and navigate to the relevant configuration for logical systems.
  Ensure that the logical system is defined and correctly assigned to the client.
  
  
  
  Review Authorizations:
  
  Ensure that the user executing the transaction has the necessary authorizations to access the RFC destination.
  
  
  
  Network Connectivity:
  
  Check for any network issues that might be preventing the connection to the target system.
  Ensure that firewalls or other network security settings are not blocking the connection.

  Logs: Check system logs (transaction SM21) for any additional error messages that might provide more context about the issue.
  
  By following these steps, you should be able to resolve the RMXTDIA021 error and establish the necessary RFC connection.
