  Solutions to GW907 Error
  
  
  Check Memory Allocation:
  
  Ensure that the SAP system has sufficient memory allocated. You can check the instance profile parameters related to memory (e.g., abap/heap_area_dia, abap/heap_area_nondia, etc.) and adjust them as necessary.
  
  
  
  Monitor System Resources:
  
  Use monitoring tools to check the memory usage of the SAP system and the underlying operating system. Look for any processes that may be consuming excessive memory.
  
  
  
  Review Configuration:
