How To Fix COM_PRODUCT_API057 - Specified RFC destination &1 is not defined

SAP Error Message - Details

• Message type: E = Error

• Message class: COM_PRODUCT_API - Messages for Product Interfaces

• Message number: 057

• Message text: Specified RFC destination &1 is not defined

What causes this issue?

The RFC destination &V1& is not defined. You cannot upload products
without a valid RFC destination because this is used to determine the
OLTP System to which the product data will be transferred.

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?

You can display a list of RFC destinations available using the possible
entries button.
Using transaction SM59 you can define any missing RFC destinations.
You can also assign RFC destinations to the object class MATERIAL using
transaction R3AC4. These RFC destinations are used to activate the BTE
(Business Transaction Event) interface for material master data in the
relevant OLTP System, which is accessed via the specified RFC
destination. The BTE interface enables a delta download to be performed
for material master data from an OLTP System to the CRM System. These
RFC destinations are also used for the upload and are displayed in the
possible entries help for selection.
The RFC destinations assigned using transaction R3AC4 form a subset of
the RFC destinations defined using transaction SM59. If delta downloads
are not being performed, meaning that no entries have been assigned to
object class MATERIAL or that the <LS>Inactive</> indicator has been
set for the maintained entries, then the RFC destinations defined with
transaction SM59 are used for the upload and are displayed in the
possible entries help for selection.

• What is the cause and solution for SAP error message COM_PRODUCT_API057 - Specified RFC destination &1 is not defined ?

  The SAP error message COM_PRODUCT_API057 indicates that the specified RFC (Remote Function Call) destination is not defined in the system. This error typically occurs when a program or function module attempts to call a remote system or service, but the destination it is trying to reach has not been configured in the SAP system.
  Cause:
  
  Missing RFC Destination: The specified RFC destination does not exist in the SAP system.
  Incorrect RFC Name: The name of the RFC destination may be misspelled or incorrectly specified in the code or configuration.
  Authorization Issues: The user may not have the necessary authorizations to access the specified RFC destination.
  Network Issues: There may be network connectivity issues preventing access to the remote system.
  
  Solution:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 in the SAP GUI.
  Look for the specified RFC destination in the list.
  If it does not exist, you will need to create it. Click on "Create" and fill in the necessary details (e.g., target host, system number, client, user credentials).
  
  
  
  Verify RFC Name:
  
  Ensure that the name of the RFC destination used in the program or configuration matches exactly with what is defined in SM59.
  
  
  
  Test the RFC Connection:
  
  In SM59, select the RFC destination and click on "Connection Test" to verify that the connection can be established successfully.
  
  
  
  Check Authorizations:
  
  Ensure that the user executing the program has the necessary authorizations to use the RFC destination. This may involve checking roles and profiles assigned to the user.
  
  
  
  Review Network Configuration:
  
  If the RFC destination is defined correctly but still not working, check for any network issues that may be preventing access to the remote system.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration parameters, refer to SAP documentation or consult with your SAP Basis team for assistance.

  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to RFC destinations or the error message COM_PRODUCT_API057.
  
  
  Logs and Traces: If the issue persists, consider checking system logs (transaction SM21) or enabling traces to gather more information about the error.
  
  
  By following these steps, you should be able to resolve the error message COM_PRODUCT_API057 and successfully configure the required RFC destination.
