  The error is triggered when the system detects that client handling is not properly defined in your code. In SAP, client handling is crucial for ensuring that data is correctly managed across different clients in a multi-client environment. The annotation @ClientHandling.type is used to specify how the data should be handled concerning the client.
  Solution:
  To resolve this error, you need to ensure that you are using the @ClientHandling annotation correctly in your ABAP code. Here are the steps to address the issue:

  @ClientHandling.type: #EXCLUDED - for excluded client handling.
  
  Example:
  @AbapCatalog.sqlViewName: 'ZMY_VIEW'
  @ClientHandling.type: #MANDATORY
  define view ZMyView as select from my_table
  {
      key field1,
      field2
  }
  
  
  Check for Other Annotations: Ensure that other relevant annotations are also correctly defined in your code, as they may affect client handling.
