How to calculate and display a new field on a grid?

(0) ShareShare

Posted on by Robert Herrmann 790

I'm new to AX development.  I have created a grid control with a few fields.  One field is named Qty and another field is named ScrapQty.  I now want to add another field named Remainder.  Remainder = Qty - ScrapQty.  But I can't figure out how to do this.  Can anyone help?

    Hi Robert,

    You would use a display method on the table which is linked to your grid.

    (search for 'display' on the AOT tables node to have a reference.

    In this method you'll have 1 line:

    return this.Qty - this.ScrapQty

    Go back to your form with the grid, add a new control of the Type Real, specify the datasource and don't specify a field, but use the method property to insert the name of your display method.

    You should have a calculated field by now.

    Here a link to MSDN where these "Display" fields are explained: msdn.microsoft.com/.../aa595058.aspx

    Ok, thanks for the help.  But I get a syntax error when I try this.  Here is my code:

    display UnRecoveredScrap GetUnrecoverableScrap(wfsProdJournalRoute prodJournalRoute)

    {

         real UnRecoveredScrap = this.QtyGood - this.NGK_RecoverableScrapQty;

        Return UnRecoveredScrap;

    }

    The first line is underlined in red so I assume the syntax error is here.  What am I doing wrong?

    I believe your method heading should be:

    display real GetUnrecoverableScrap(wfsProdJournalRoute prodJournalRoute)
