• What is the cause and solution for SAP error message UJS_EXCEPTION015 - Recommended to increase ABAP/buffersize to 2G to activate ApShell ?

  The SAP error message UJS_EXCEPTION015 indicates that there is an issue related to the buffer size in the ABAP environment, specifically when trying to activate the ApShell (Application Shell). This error typically arises when the buffer size allocated for ABAP is insufficient to handle the current workload or the specific application being executed.
  Cause:
  
  Insufficient Buffer Size: The ABAP buffer size is set too low to accommodate the data being processed. This can happen if the default settings are not sufficient for the complexity or size of the application.
  High Data Volume: If the application is processing a large volume of data or complex operations, it may require more memory than what is currently allocated.
  Configuration Issues: The system may not be configured optimally for the workload, leading to performance issues and errors.
  
  Solution:
  To resolve the UJS_EXCEPTION015 error, you can take the following steps:
  
  
  Increase ABAP Buffer Size:
  
  Access the SAP system with appropriate administrative privileges.
  Navigate to the transaction code RZ10 (Profile Parameter Maintenance).
  Look for the parameter abap/buffersize.
  Increase the value to 2G (2 Gigabytes) or higher, depending on your system's capacity and requirements.
  Save the changes and activate the profile.
  
  
  
  Restart the SAP System:
  
  After making changes to the profile parameters, you will need to restart the SAP system for the changes to take effect.
  
  
  
  Monitor System Performance:
  
  After increasing the buffer size, monitor the system performance to ensure that the changes have resolved the issue and that there are no new errors.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may provide additional guidance or updates related to this error.
