• What is the cause and solution for SAP error message UMC112 - RFC destination & is no BW System ?

  The SAP error message UMC112 typically indicates that there is an issue with the RFC (Remote Function Call) destination configuration, specifically that the system is unable to find a BW (Business Warehouse) system associated with the specified RFC destination. This can occur in various scenarios, such as when trying to access BW data or when executing certain BW-related functions.
  Cause:
  
  
  Incorrect RFC Destination Configuration: The RFC destination may not be correctly configured in the SAP system. This could be due to incorrect connection parameters, such as the target system's hostname, system number, or client number.
  
  
  Missing BW System: The BW system that the RFC destination is supposed to connect to may not be available or may not be properly set up in the SAP landscape.
  
  
  Network Issues: There could be network connectivity issues preventing the SAP system from reaching the BW system.
  
  
  Authorization Issues: The user or service account being used to connect to the BW system may not have the necessary authorizations.
  
  
  System Configuration: The BW system may not be configured to accept connections from the source system.
  
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
