Field help (ALHSRT)

This field allows you to sort the data elements that will be displayed in the inquiry - in the order in which they appear on the lines in this table. Sorting may be either done Ascending or Descending.

You must set this field to a value other than No to be able to Group data (since otherwise the data would be unorganized). But, in a simple inquiry with no grouping (no roll up capability), you can sort data but not necessarily group it (e.g., for a listing of sales orders).
