Field help (TGPFIEORD) 

This field is used to define the presentation order of the information. Two fields can have the same order number. In this case, a second alphabetical sort is carried out on the field codes to determine their display order.

NB: Even if it is possible to define several items of information in the selection support, only the first fifteen lines are displayed.

In addition, the field used as a sort criterion must figure amongst these first fifteen lines.
