• What is the cause and solution for SAP error message UMC105 - Enter an RFC destination; the BW system is a remote R/3 System ?

  The SAP error message UMC105 indicates that the system requires an RFC (Remote Function Call) destination to connect to a remote R/3 system, typically in the context of a Business Warehouse (BW) system trying to access data or perform operations on a remote system.
  Cause:
  The error occurs when:
  
  The BW system is configured to connect to a remote R/3 system, but the required RFC destination is not defined or is incorrectly configured.
  The RFC destination may not be maintained in the SAP system, or it may be inactive.
  There could be network issues preventing the BW system from reaching the remote R/3 system.
  The user may not have the necessary authorizations to access the RFC destination.
  
  Solution:
  To resolve the UMC105 error, follow these steps:
  
  
  Check RFC Destination:
  
  Go to transaction code SM59 in the SAP GUI.
  Look for the RFC destination that the BW system is supposed to use to connect to the R/3 system.
  Ensure that the destination is defined and correctly configured (e.g., the target host, system number, and client).
  
  
  
  Test the RFC Connection:
  
  In SM59, select the RFC destination and click on the "Test Connection" button to verify that the connection to the remote R/3 system is working.
  If the test fails, check the configuration settings, network connectivity, and ensure that the remote system is up and running.
  
  
  
  Check Authorizations:
  
  Ensure that the user executing the BW process has the necessary authorizations to access the RFC destination.
  You may need to check the roles and profiles assigned to the user.
  
  
  
  Maintain Logical System:
  
  Ensure that the logical system for the BW and R/3 systems is correctly defined in transaction SCC4.
  Make sure that the logical system names are correctly assigned in the respective systems.
  
  
  
  Check BW Configuration:
  
  Review the BW configuration settings related to the remote R/3 system, such as InfoSources, DataSources, and any relevant settings in the BW system.
  
  
  
  Network Issues:
  
  If the connection test fails, check for any network issues that may be preventing communication between the BW and R/3 systems. This may involve checking firewalls, VPNs, or other network configurations.
  
  
  
  Related Information:
  
  RFC Destinations: RFC destinations are used in SAP to define how systems communicate with each other. They can be configured as TCP/IP connections, and they can be either synchronous or asynchronous.
  Transaction Codes:
  
  SM59: Manage RFC destinations.
  SCC4: Maintain logical systems.
  SU01: User maintenance to check user authorizations.
  
  
  Documentation: Refer to SAP Help documentation for more details on configuring RFC destinations and troubleshooting connectivity issues.
  
  By following these steps, you should be able to resolve the UMC105 error and establish a successful connection between your BW system and the remote R/3 system.
