Make the Field Mandatory

Posted on by Johnson_Patrick 100

Hi,

I want to make non-primary keys of the table mandatory on a list part page. For eg: If i am working with Sales Order Subform Page and there is a field "Expiration Date" field on the sales lines. If the user doesn't enter the Expiration Date on the lines before exiting from the line, the system should throw error asking to fill the field and stay on the page. User can revert back the changes if he doesn't wish to specify the expiration date.

As simple as it might sound, I have tried it using ShowMandatory, NotBlank & Testfields yet it doesnt work the way, i want it to work. 

if anybody had solved this before, please comment

Thanks

Johnson Patrick

    I solved the problem by making the page as DelayedInsert true & then using testfield i validated the fields which are mandatory on OnInsert & OnModify triggers of the table.

    Thanks for your suggestions.

    Try giving trigger OnValidate on any other field which is after the specified field.

    It might work.

    You can also try it on Action Button (Trigger OnAction).

    You can try page triggers trigger "OnClosePage"

     trigger OnClosePage()
        begin
            if rec.ExpirationDate = '' then//Single Quotation Marks without space
                Error('Enter the date');
        end;

    Please let me know.

    Hope this helps.

    You can use the

    ShowMandatory = true;

    Importance = Promoted;

    Or

    You can code on trigger OnValidate of the specified field.

    IF Rec."Expiration Date"='' THEN//Single Quotation Mark without space.

    Error('enter the expiration date');

    Thank You.

    No that doesnt work. System throws error immediately after the record is inserted.
