  Review Custom Code: If there is any custom code related to the tree control, review it to ensure that it adheres to the column limits. Look for any loops or conditions that might be adding columns incorrectly.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific tree control you are using to understand the maximum column limit and any related constraints.
