Sie können Setup ein unsichtbares Berechnetes Element, fasst dieser Plan Verhältnis Feld Name es zum Beispiel als SUMMARY_FIELD und dann hinzufügen, wenn-VALIDATE-ITEM-Trigger für jeden Plan Verhältnis Punkt der Datensätze wie folgt aus:
BEGIN
IF :SUMMARY_FIELD>100 THEN
message('nok'); --or whatever alert you like
RAISE Form_Trigger_Failure;
END IF;
END;
PS. Wie man Berechnetes Element erstellen:
Um ein berechnetes Element zu erstellen:
1. In the Object Navigator, create a new interface item (make sure it is a control item).
Tip: The item's datatype must be compatible with the calculation you wish to use to
compute the item's value. For example, if you wish to compute an item's value with the
Sum function, create an interface item of datatype Number.
2. Double-click the item's object icon to display the Property Palette.
3. Under the Calculation node, set the item's Calculation Mode property to Formula or
Summary.
4. If you set Calculation Mode to:
Formula, click on the Formula property, click the More button to display the Formula
dialog, and type a PL/SQL expression to define the formula. Click OK to compile the
expression.
Summary, use the Summary Function popList to select a summary type, then use the
Summarized Block and Summarized Item popLists to select the block and item whose
values will be summarized to compute a value for the calculated item.
