  The SAP error message AG002, which states "Error in RFC call-up: &1, &2," typically indicates that there is an issue with a Remote Function Call (RFC) in the SAP system. This error can occur in various scenarios, such as when trying to execute a function module remotely or when there is a problem with the communication between systems.
  Causes:
  
  Network Issues: Problems with the network connection between the SAP systems can lead to RFC call failures.
  Authorization Issues: The user executing the RFC may not have the necessary authorizations to perform the action.
  Configuration Errors: Incorrect configuration of the RFC destination (SM59) can cause this error.
  Function Module Issues: The function module being called may not exist, may be inactive, or may have been changed.
  System Load: High load on the SAP system can lead to timeouts or failures in processing RFC calls.
  Version Mismatch: If there are different versions of the function module in the systems involved, it can lead to compatibility issues.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there is proper network connectivity between the systems involved in the RFC call.
