Hello, Francesco.

You can add some lines of code to the SPE of your function. SPEPTH, for instance.

Add the following snippet:

$ACTION
 Case ACTION
  When "CLE_GAUCHE" : Gosub CLE_GAUCHE
 Endcase
Return

$CLE_GAUCHE

  CRITERE+="[F:ZZZ]FIELD='VALUE'"

Return

, where ZZZ is your table abbreviation, FIELD is the field you want to control and VALUE is the filter you wish to apply.

Regards,

Pedro R.
