Formula fields show no data in table view

Sometimes my formula-fields don't show data in some records in the table view and the form view while in others the result is shown. My formula is correct because when renewing the window, the data is shown and other (formula)fields are empty. Could this have to do with the runtime that not all data is downloaded in time?

What could I do the get rid of this problem?

    Hi

    Can you share with us the formula that you are using? Does it include a select command by any chance, as these don't update automatically?

    Regards John

    Hi John,

    There is no select but this formula does refer to another series of formulas; below is the code I'm using. The first first part (if '# werven' = 1 then) are all formulas in the same table. The second part (if '# werven' > 1 then) are references to a subtable.

    if '# werven' = 1 then
    if sum(Prestaties.Laden) >= 0.25 and sum(Prestaties.Lossen) >= 0.25 then
        'Start lossen werf 1' - 'Start laden werf 1' + 'Lossen werf 1' - 'Pauze werf 1'
    else
        if 'Laden werf 1' >= 0.25 and 'Lossen werf 1' = 0 then
            'Stop werf 1' - 'Start laden werf 1' - 'Pauze werf 1'
        else
            if 'Laden werf 1' = 0 and 'Lossen werf 1' = 0 then
                'Stop werf 1' - 'Start werf 1' - 'Pauze werf 1'
            else
                if 'Laden werf 1' = 0 and 'Lossen werf 1' >= 0.25 then
                    'Start lossen werf 1' - 'Start werf 1' - 'Pauze werf 1' + 'Lossen werf 1'
                end
            end
        end
    end
else
    if '# werven' > 1 then
        if 'Start werf 1' = 0 then
            'Laden werf 1'
        else
            if sum(Prestaties.Laden) >= 0.25 and sum(Prestaties.Lossen) >= 0.25 then
                max(Prestaties.'Start lossen') - min(Prestaties.'Start laden') -
                sum(Prestaties.Pauze) +
                sum(Prestaties.Lossen)
            else
                if sum(Prestaties.Laden) >= 0.25 and sum(Prestaties.Lossen) = 0 then
                    max(Prestaties.'Einde werf') - min(Prestaties.'Start laden') -
                    sum(Prestaties.Pauze)
                else
                    if sum(Prestaties.Laden) = 0 and sum(Prestaties.Lossen) = 0 then
                        max(Prestaties.'Einde werf') - min(Prestaties.'Start werf') - sum(Prestaties.Pauze)
                    else
                        if sum(Prestaties.Laden) = 0 and sum(Prestaties.Lossen) >= 0.25 then
                            max(Prestaties.'Start lossen') - min(Prestaties.'Start werf') -
                            sum(Prestaties.Pauze) +
                            sum(Prestaties.Lossen)
                        end
                    end
                end
            end
        end
    end
end

      Actually, there is a select command in the formula's that are mentioned in the first section; here's the code:

      let x := number(Datum) + Medewerkers.Id;
first((select Prestaties where 'Uniek nr.' = x or 'Unique nr.' = x).Laden)

    I see that the second line of your code says

        if sum(Prestaties.Laden) >= 0.25 and sum(Prestaties.Lossen) >= 0.25 then

    and I wonder if it should say

    if 'Laden werf 1' >= 0.25 and 'Lossen werf 1' >= 0.25 then

    I don't pretend to understand what your code is doing but this seems to fit the pattern better.

    Regards John

    Thank you for the feedback, John. Your previous quote ("Does it include a select command by any chance, as these don't update automatically?") allowed me to solve the problem. I removed the select commands and the error doesn't appear to be there anymore. Thank you very much indeed! Just out of curiosity, is there a way (e.g. using a button) to update everything?
