• What is the cause and solution for SAP error message RT476 - Incoming calls (ARFCRSTATE table) ?

  The SAP error message RT476 typically relates to issues with the ARFCRSTATE table, which is used to manage the state of asynchronous RFC (Remote Function Call) connections in SAP systems. This error can occur when there are problems with the communication between different SAP systems or when the state of the RFC connections is not properly maintained.
  Cause:
