• What is the cause and solution for SAP error message BT661 - Only specify target server or target server group - not both ?

  The SAP error message BT661 indicates that there is a conflict in the configuration of a target server and a target server group in a background job or a similar process. Specifically, it means that both a target server and a target server group have been specified, which is not allowed. You can only specify one of them at a time.
  Cause:
  The error occurs when:
  
  A background job or process is configured to run on both a specific target server and a target server group simultaneously.
  This can happen due to incorrect settings in the job definition or when using transaction codes like SM36 (for job scheduling) or similar.
  
  Solution:
  To resolve the error, you need to ensure that you only specify either a target server or a target server group, but not both. Here are the steps to fix the issue:
  
  
  Access the Job Definition:
  
  Go to transaction code SM36 to define or modify the background job.
  
  
  
  Check Target Server Settings:
  
  In the job definition screen, look for the section where you can specify the target server or target server group.
  If you have specified a target server (e.g., a specific application server), remove any entry in the target server group field.
  Conversely, if you have specified a target server group, ensure that the target server field is left blank.
  
  
  
  Save the Changes:
  
  After making the necessary adjustments, save the job definition.
  
  
  
  Re-run the Job:
  
  Once the job is correctly configured, you can re-run it to see if the error persists.
