Question

this is my first attempt at Stack overflow, so hopefully you all can help me. I’d be happy to start contributing here, it’s been such a useful tool in the past.

Okay, so I am trying to write a report that charts the total past due hours of a manufacturing facitility. What I have is a conglomaration of tables, that list each manufacturing order and give a due date and a completion date. The person running the report enters a date range and I want to generate a chart with dates along the x-axis and the sum of past due hours on the y-axis. Maybe I am missing something with an eimplementation of the three-formule trick, but i can’t get this to work. I can group by due date, but that only gives me the total orders that went past due on a given date.

What I need is something like the following, that is chartable:

    For each (date in DateRange) {
       If (Due Date < i) && (Comp Date > i) {
          Past Due Hours = Past Due Hours + manufacturing order Hours
       }
    }

I know it’s not in Crystal Syntax, I was just trying to get the picture across. Any help?

This sort’ve question comes up regular- if i’ve understood correctly. You have something like this?

OrderNum DueDate  CompletedDate
1        01/01/01 01/02/01
2        01/01/01 01/01/01
3        01/02/01 01/03/01
4        01/02/01 01/02/01

Now the first thing you need to do is get a table (there are other similar approaches) with all dates in it and join into your dataset so you’ll end up with:

OrderNum DueDate  CompletedDate Date
1        01/01/01 01/02/01      01/01/01
2        01/01/01 01/01/01      01/01/01
3        01/02/01 01/03/01      01/01/01
4        01/02/01 01/02/01      01/01/01
1        01/01/01 01/02/01      01/02/01
2        01/01/01 01/01/01      01/02/01
3        01/02/01 01/03/01      01/02/01
4        01/02/01 01/02/01      01/02/01
1        01/01/01 01/02/01      01/03/01
2        01/01/01 01/01/01      01/03/01
3        01/02/01 01/03/01      01/03/01
4        01/02/01 01/02/01      01/03/01

Next you need to add a field which determines whether the order is {@overdue}:

if {table.duedate} < {table.date} and {table.completeddate} > {table.date} then 
 1
else 
 0;

Make sure you select default values for null values to avoid any anomalies).

You can now create a graph plotting sum({@overdue}) against {table.date}
