• What is the cause and solution for SAP error message DBPROC_PROXY035 - Interface pool & already exists ?

  The SAP error message DBPROC_PROXY035 typically indicates that there is an issue with the interface pool in the database, specifically that an interface pool already exists when the system is trying to create or register a new one. This can occur in various scenarios, such as during the execution of a program or when trying to access a specific database function.
  Cause:
  
  
  Duplicate Interface Pool: The error usually arises when there is an attempt to create an interface pool that already exists in the database. This can happen due to:
  
  A previous session or transaction that did not close properly.
  A programming error where the same interface pool is being instantiated multiple times.
  Issues with database connections or transactions that lead to inconsistencies.
  
  
  
  Database Locking Issues: Sometimes, if the database is locked or if there are concurrent processes trying to access the same resource, it can lead to this error.
  
  
  Configuration Issues: Incorrect configuration settings in the SAP system or the database can also lead to this error.
  
  
  Solution:
  
  
  Check for Existing Interface Pools: 
  
  Use transaction codes like SE11 or SE80 to check if the interface pool already exists in the system. If it does, you may need to modify your code to avoid creating it again.
  
  
  
  Review Code Logic: 
  
  Ensure that your ABAP code or any custom programs are not attempting to create the same interface pool multiple times. Implement checks to see if the pool already exists before trying to create it.
  
  
  
  Database Connection Management: 
  
  Ensure that database connections are being managed properly. Close any open connections that are no longer needed.
  
  
  
  Restart the Application: 
  
  Sometimes, simply restarting the application or the SAP instance can resolve temporary issues related to locks or stale connections.
  
  
  
  Check for Locks: 
  
  Use transaction SM12 to check for any locks that might be causing the issue. If you find any locks related to the interface pool, you may need to release them.
  
  
  
  Consult SAP Notes: 
  
  Check the SAP Support Portal for any relevant SAP Notes that might address this specific error. There may be patches or updates that resolve underlying issues.
  
  
  
  Contact SAP Support: 
  
  If the issue persists after trying the above solutions, consider reaching out to SAP Support for further assistance. Provide them with detailed information about the error, including any relevant logs or transaction codes.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), and SM12 (Lock Entries) for troubleshooting.
  SAP Documentation: Review SAP documentation related to database management and interface pools for best practices and guidelines.
  Performance Monitoring: Use transaction ST22 (Dump Analysis) and SM21 (System Log) to check for any related dumps or logs that might provide more context on the error.
  
  By following these steps, you should be able to identify the cause of the DBPROC_PROXY035 error and implement a suitable solution.
