• What is the cause and solution for SAP error message DBOSC006 - Error while saving DBCON; key '&1' already exists ?

  The SAP error message DBOSC006 indicates that there is an issue with saving a database connection (DBCON) because a key (in this case, the connection identifier) already exists in the system. This typically occurs when you attempt to create a new database connection with a name that is already in use.
  Cause:
  
  Duplicate Key: The most common cause of this error is that you are trying to create a DBCON entry with a name that already exists in the database connection table.
  Incorrect Configuration: There may be a misconfiguration in the DBCON settings or an attempt to overwrite an existing connection without proper deletion.
  System Issues: Sometimes, system inconsistencies or issues with the database can lead to this error.
  
  Solution:
  
  
  Check Existing Connections:
  
  Use transaction code DB02 or DBCON to view existing database connections.
  Look for the connection name (key) that you are trying to create. If it exists, you may need to either modify it or delete it if it is no longer needed.
  
  
  
  Modify or Delete Existing DBCON:
  
  If the connection already exists and you want to change its settings, you can modify the existing DBCON entry instead of creating a new one.
  If the existing connection is not needed, you can delete it using the DBCON transaction.
  
  
  
  Use a Unique Key:
  
  If you need to create a new connection, ensure that you are using a unique key that does not conflict with existing entries.
  
  
  
  Check for System Issues:
  
  If you believe there should not be a duplicate entry, check for any system inconsistencies or issues with the database. You may need to consult with your database administrator or SAP support.
  
  
  
  Related Information:
  
  
  Transaction Codes:
