How To Fix DMC_IU080 - Client of the RFC destination is not equal to the selected client

SAP Error Message - Details

• Message type: E = Error

• Message class: DMC_IU - DMC: Messages for Integrated Upgrade

• Message number: 080

• Message text: Client of the RFC destination is not equal to the selected client

What causes this issue?

The current function is supposed to be executed for a certain client in
the target system. However, the used RFC-connection sports a different
client. To start the function the specified client and the client of the
RFC-connection have to be the same, so the actual function is cancelled.
Exceptions to the rule are the two steps "Create Export" and "Start
Export" which can also be started via RFC-connection with client '000'.

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?

Make sure the client of the RFC-connection and the target client
of the receiver system are the same and restart the function.
Alternatively a RFC-connection with client '000' can also be applied for
the worksteps 'Create Export' and 'Start Export'.

• What is the cause and solution for SAP error message DMC_IU080 - Client of the RFC destination is not equal to the selected client ?

  The SAP error message DMC_IU080 indicates that there is a mismatch between the client of the RFC (Remote Function Call) destination and the client that is currently selected in the SAP system. This error typically occurs in scenarios involving data migration or integration processes, particularly when using tools like SAP Data Migration Cockpit or SAP Landscape Management.
  Cause:
  The error arises when:
  
  The RFC destination is configured to connect to a specific client, but the client you are currently logged into or trying to use is different.
  The settings in the RFC destination do not match the client context of the transaction or process you are executing.
  
  Solution:
  To resolve the DMC_IU080 error, you can follow these steps:
  
  
  Check the Current Client:
  
  Verify the client you are currently logged into in your SAP system. You can find this information in the SAP GUI at the top right corner of the screen.
  
  
  
  Review RFC Destination Settings:
  
  Go to transaction SM59 (RFC Destinations) in your SAP system.
  Locate the RFC destination that is causing the issue.
  Check the configuration of the RFC destination, particularly the "Logon & Security" tab.
  Ensure that the "Client" field matches the client you are currently using.
  
  
  
  Adjust the Client in the RFC Destination:
  
  If the RFC destination is set to a different client, you can either:
  
  Change the client in the RFC destination to match your current client.
  Log into the correct client that matches the RFC destination.
  
  
  
  
  
  Test the RFC Connection:
  
  After making any changes, use the "Connection Test" feature in SM59 to ensure that the RFC destination is working correctly.
  
  
  
  Check for Authorization Issues:
  
  Ensure that the user you are logged in as has the necessary authorizations to access the specified client and perform the required operations.
  
  
  
  Consult Documentation:
  
  If you are using specific tools (like SAP Data Migration Cockpit), refer to the relevant documentation for any additional configuration or prerequisites that may be required.
  
  
  
  Related Information:
  
  RFC Destinations: These are configurations that define how SAP systems communicate with each other. They include details like the target system, client, user credentials, and connection type.
  Clients in SAP: A client in SAP is a self-contained unit with separate master records and its own set of tables. Each client can represent a different business entity or environment (e.g., development, testing, production).
  SAP Notes: Check SAP Notes for any known issues or patches related to the DMC_IU080 error, as there may be specific fixes or recommendations provided by SAP.
  
  By following these steps, you should be able to resolve the DMC_IU080 error and ensure that your RFC destination and client settings are aligned correctly.
