Field help (ASTDSAIAFF)

With regard to each field, specify which are the fields that should be displayed or Entered during maintenance. The fields constituting the principal key for the table are always displayed; those that defined as hidden do not appear in the entry grid.

It should be noted that, by right click on the fields in the Entry type column, it is possible to globally update all the fields (other than those linked to the principal key of the table) with one of three values Enter, Display, or Hidden.
