  Review Changes: Check the changes you are trying to implement in the segment attributes. Ensure that you are not inadvertently changing the hierarchical level of the segment.
  
  
  Revert Changes: If you have made changes that caused this error, revert them to the previous state where the segment structure was valid.

  Consult Documentation: Refer to SAP documentation or guidelines regarding segment attributes and their allowed changes. This can provide insights into what modifications are permissible.

  Testing: After making the necessary adjustments, test the changes in a development or test environment before applying them to production.
