  Causes:
  
  System Load: High system load or resource contention can lead to delays in scheduling RFC calls.
  Network Issues: Network latency or connectivity problems between the SAP systems can cause delays.
  Configuration Issues: Incorrect configuration of the RFC destination or the background job settings may lead to scheduling problems.

  Network Diagnostics: Perform network diagnostics to ensure that there are no connectivity issues between the systems involved in the RFC call.
