      Help and question about using Sum function

      Post

      FMP 10 on Mac and PC

      I have a Table that we use to keep track of hours worked and personal hours.  This one table tracks six people.  A new record is made every week for each person.  So six new records are made each week.  How can I keep a running total of the personal hours for each person, but limit what it totals to just this year, 2011?  I really want to make sure it only totals each person's personal hours and not just sum all six people's personal hours.  Does this make sense?  Is this possible?

          You can use either a summary field or a calculation with the sum function for this.

          In a summary report, you could perform a find for all 2011 records and sort by person to get your totals.

          From a portal, you can include the year in the portal's relationship. Then the same summary field will report the total for the portal. A sum function defined in the layout's table can report the total of the portal also. Unless there is some FileMaker 11 portal filtering going on which isn't the case here, I prefer sum to compute a portal total as it refreshes more smoothly should you edit a portal record.

          Here's one sample relationship that could work for your portal:

          MainTable::gYear = PortalTable::Year AND
          MainTable::PersonID = POrtalTable::PersonID

          gYear can be a global field where you enter the year you want for the portal. PortalTable::Year can be a calculation field that returns Year (dateField) to produce a number to match with gYear.
