Accurate OM booked orders report

Question

My objective is to develop a Booked Orders Report in Discoverer and I'm pretty new to Discoverer 10g.
My logic to property display the records is -- for each order in OM that header status is booked, determine if ANY lines are still open by looking at the Open Flag and if any line is still open, display all lines associated with that order.
example: SO# 100 has 4 lines where line 1 is open awaiting shipping (open_flag = 'Yes') and other 3 are closed (open_flag = 'No').
maybe I'm going about this the long way so if you know a cleaner way, please share....
The best logic in discoverer that I can come up with (based on the various line status fields) is that I can build a new calculation called l_open_flag that is setup as CASE WHEN "Order Lines".Open Flag = 'Yes' THEN '1' ELSE '0' and when I run the discoverer report, the l_open_flag is working and returning 1 or 0 as expected for each line.
The next step is to setup a second calculation to sum the l_open_flag called sum_l_open_flag and add a second non-display parameter to display any order where header level status is 'booked' and the sum_l_open_flag > 0.
the problem is that when I try to sum l_open_flag discoverer throws up a warning that I'm combining detail data point and an aggregated data point -- which I agree.
After adding the new condition to include orders where sum_l_open_flag > 0, I still only get just the one line item out of the 4 lines on the order that is still open.
Hope this is clear like oracle and thanks,
Rob

Answer 1

Hi rob,
From your example i understood is if open_flag=Yes it is open and when No then it is closed.Your going in the right path by taking the case as you mentioned.
But why are you taking the second condition sum(l_open_flag).definately it will throw warning.Why do you need this condition?Can you be clearer
I sugest you take a second calculation as calculation2=l_open_flag>0,this suggests that when you are giving zero(0) it says that you want all closed sales orders.
Anything more can you give more explanation.
