  The SAP error message BGRFC403: Scheduler number not found typically occurs in the context of the Background RFC (BGRFC) framework, which is used for asynchronous communication between different SAP systems or between different instances of the same system. This error indicates that the system is unable to find a specific scheduler number that is required for processing the BGRFC requests.
  Causes:
  
  Missing Scheduler Configuration: The scheduler number may not be configured correctly in the system.
  System Configuration Issues: There may be issues with the BGRFC configuration in the SAP system, such as missing or incorrect entries in the relevant tables.

  Network Issues: Problems with network connectivity or communication between systems can also lead to this error.
  System Load: High system load or resource constraints may prevent the scheduler from being recognized or functioning properly.
  
  Solutions:
  
  
  Check Scheduler Configuration:
