How To Fix DRF_OUTBOUND166 - For outb impl. &1 an RFC destination must be defined in Customizing

SAP Error Message - Details

• Message type: E = Error

• Message class: DRF_OUTBOUND - Messages for Outbound Services

• Message number: 166

• Message text: For outb impl. &1 an RFC destination must be defined in Customizing

What causes this issue?

You have not defined an RFC destination for an outbound implementation
that uses RFC as a communication channel. The RFC destination
corresponds to the receiver system.

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?

In Customizing, define an RFC destination as a receiver system for this
outbound implementation.

• What is the cause and solution for SAP error message DRF_OUTBOUND166 - For outb impl. &1 an RFC destination must be defined in Customizing ?

  The SAP error message DRF_OUTBOUND166 indicates that for the outbound implementation specified (denoted by &1), an RFC (Remote Function Call) destination must be defined in the system's Customizing settings. This error typically occurs in the context of SAP's Data Replication Framework (DRF) when trying to set up or execute outbound data replication.
  Cause:
  The error is caused by the absence of a defined RFC destination for the specified outbound implementation. The RFC destination is necessary for the system to know where to send the replicated data. This can happen due to:
  
  The RFC destination not being created or configured in the system.
  Incorrect or missing settings in the Customizing for the outbound implementation.
  The outbound implementation not being properly linked to an RFC destination.
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Define the RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Check if the required RFC destination exists. If it does not, create a new RFC destination.
  Ensure that the destination is configured correctly, including the target system details and connection parameters.
  
  
  
  Configure the Outbound Implementation:
  
  Go to transaction SPRO to access the Customizing settings.
  Navigate to the relevant path for Data Replication Framework settings, typically under SAP Customizing Implementation Guide > Logistics > Data Replication Framework > Outbound Implementation.
  Find the outbound implementation that corresponds to the error message and ensure that it is linked to the correct RFC destination.
  
  
  
  Check Authorization:
  
  Ensure that the user executing the replication has the necessary authorizations to use the RFC destination.
  
  
  
  Test the RFC Connection:
  
  In transaction SM59, select the RFC destination and use the "Connection Test" option to verify that the connection is working properly.
  
  
  
  Review Logs:
  
  Check the application logs (transaction SLG1) for any additional error messages or details that might provide more context about the issue.

  RFC Destinations: These are used in SAP to define how systems communicate with each other. They can be configured for various types of connections, including TCP/IP, HTTP, etc.
  Data Replication Framework (DRF): This is a tool in SAP that allows for the replication of master data across different systems. Proper configuration is crucial for successful data transfer.
  Customizing Settings: These settings are essential for defining how various components of SAP interact with each other, including the setup of outbound implementations.
  
  By following these steps, you should be able to resolve the DRF_OUTBOUND166 error and ensure that your outbound implementation is correctly configured to use the appropriate RFC destination.
