BUAVC013 - Details

• The SAP error message BUAVC013 indicates that there is an issue with the number of parallel Remote Function Call (RFC) tasks that are being executed. This error typically arises when the system is trying to execute more parallel RFC tasks than the configured limit allows.
  
  Cause:
  
  Configuration Limits: The system has a predefined limit for the number of parallel RFC tasks that can be executed. If the application or process attempts to exceed this limit, the error will occur.
  System Load: High system load or resource constraints may lead to the inability to handle additional parallel RFC calls.
  Incorrect Settings: The settings for the number of parallel RFC tasks may not be configured correctly in the system.
  
  
  Solution:
  
  
  Check Configuration:
  
  Go to transaction RZ10 or RZ11 to check the profile parameters related to RFC. Look for parameters like rfc/max_active or rfc/max_connections.
  Adjust the parameters to allow for a higher number of parallel RFC tasks if necessary. Be cautious
