• The SAP error message FKK_ML_SRV013: No RFC connection defined typically occurs in the context of SAP's Contract Accounts Receivable and Payable (FI-CA) module, particularly when there is an issue with the Remote Function Call (RFC) connection that is required for certain operations, such as data transfer or communication between different SAP systems or between SAP and external systems.
  
  Cause:
  
  Missing RFC Connection: The most common cause of this error is that the required RFC connection has not been defined in the SAP system.

  Network Issues: There could be network-related issues preventing the connection from being established.
  System Configuration: The system may not be properly set up to handle the specific transaction or function module that requires the RFC connection.
