  The SAP error message ON152 ("Selections of all classes were removed") typically occurs in the context of the SAP system when dealing with selection criteria in reports or transactions that involve class-based selection.

  Consult Documentation: Refer to the SAP documentation or help files related to the specific transaction or report you are using to understand the expected selection criteria and class relationships.
