Calculate date

Navi_Learner · 2006-01-19

Hi I have a question. In our current Cash report, we have the posting date, and the due date. How to calculate the days when custoer pay the cash, i.e due date - posting date. I tried it, but it didn't work. Thanks in advance!

"Due date" - "Posting date" should work fine. It returns an integer, which is the number of days between both dates.

I create a variable with integer data type, but when I minus the two, the result is zero. So how can I get the correct number? Thanks!

That's because your dates are the same? When I do Date1 - Date2 I get an integer with the number of days, I don't know how else to put it.

I had created a little form to test it myself, and figured maybe you'd want to see how I got it to work:

OBJECT Form 50000 Date Minus Date
{
  OBJECT-PROPERTIES
  {
    Date=01/19/06;
    Time=12:24:17 PM;
    Modified=Yes;
    Version List=;
  }
  PROPERTIES
  {
    Width=5610;
    Height=2200;
    OnOpenForm=BEGIN
                 Date2 := TODAY;
                 Date1 := CALCDATE('<-10D>',Date2);
               END;

  }
  CONTROLS
  {
    { 1000000000;TextBox;3630 ;220  ;1700 ;440  ;CaptionML=ENU=Date 1;
                                                 SourceExpr=Date1 }
    { 1000000001;Label  ;220  ;220  ;3300 ;440  ;ParentControl=1000000000 }
    { 1000000002;TextBox;3630 ;770  ;1700 ;440  ;CaptionML=ENU=Date 2;
                                                 SourceExpr=Date2 }
    { 1000000003;Label  ;220  ;770  ;3300 ;440  ;ParentControl=1000000002 }
    { 1000000004;CommandButton;220;1430;5060;550;CaptionML=ENU=Date 2 Minus Date 1;
                                                 OnPush=BEGIN
                                                          MyInteger := Date2 - Date1;
                                                          MESSAGE(FORMAT(MyInteger));
                                                        END;
                                                         }
  }
  CODE
  {
    VAR
      Date1@1000000000 : Date;
      Date2@1000000001 : Date;
      MyInteger@1000000002 : Integer;

    BEGIN
    END.
  }
}

Save it in a text file and import it into Navision. It's a form with object number 50000. If that number is already taken, just change the number to one that is available.

I don't have the liscence to import the file. I changed something. Now almost all the number are -30 whether it is paid before the due date or after the due date except the number that is paid at exact due date is correct that is zero. I still don't why. Can it give me for instance 20, 8 and etc after I minus the two date?

DenSter · 2006-01-19

I really don't know how else to explain it.... You subtract two dates and it returns an integer. This works all the time. If date 1 is before date 2 it returns a positive number, a negative number if it's after date 2, and zero if it's the same.

If you're not getting the right results then you're not programming it correctly. If it's in a report you typically want to do this in the OnAfterGetRecord trigger of the relevant dataitem. You can even put the source expression of the control to be "Posting Date" - "Due Date" and it will show the number.

post your code, variables, where you're doing this & what trigger you are using. then we can see where you are going wrong.
