• What is the cause and solution for SAP error message LT_DHAPE_REMOTE021 - Number of sessions exceeds. Limit: &1 ?

  The SAP error message LT_DHAPE_REMOTE021 indicates that the number of sessions for remote data handling has exceeded the defined limit. This typically occurs in scenarios involving remote function calls (RFC) or when using the SAP Landscape Management (LaMa) tool, where multiple sessions are trying to access the same resources concurrently.
  Cause:
  
  Session Limit Exceeded: The system has a predefined limit on the number of concurrent sessions that can be opened for remote data handling. When this limit is exceeded, the error is triggered.
  High Load: A sudden spike in the number of requests or processes that require remote data handling can lead to this error.
  Configuration Issues: The configuration settings for session limits may be set too low for the current workload.
  
  Solution:
  
  
  Increase Session Limit:
  
  You can increase the limit of concurrent sessions in the SAP system configuration. This is typically done in the instance profile parameters.
  Look for parameters like rfc/max_connections or rdisp/wp_no_btc and adjust them according to your system's capacity and requirements.
  
  
  
  Monitor and Optimize Usage:
  
  Analyze the current usage of remote sessions and identify any processes that may be consuming excessive resources.
  Optimize the processes to reduce the number of concurrent sessions, if possible.
  
  
  
  Session Management:
  
  Ensure that sessions are properly closed after their use to free up resources.
  Implement session management practices to avoid unnecessary session creation.
  
  
  
  Check for Long-Running Processes:
  
  Identify any long-running processes that may be holding onto sessions longer than necessary and optimize or terminate them if they are not needed.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may provide additional guidance or patches related to this error.
  
  
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SM50 (Process Overview) and SM66 (Global Process Overview) to monitor active processes and sessions.
  SAP Basis Team: If you are not the SAP Basis administrator, it may be necessary to involve them to make changes to system parameters or to analyze system performance.
  Documentation: Refer to SAP documentation for detailed information on session management and configuration settings.
  
  By addressing the session limit and optimizing the usage of remote data handling, you should be able to resolve the LT_DHAPE_REMOTE021 error effectively.
