How to get sum of groups in crystal report 10?

Question

I have a report with for some invoices and each invoice has some lines like this :

invoice1 2000
     line1   300
     line2   700
     line3   500
     line4   500
invoice2 1000
     line1   300
     line2   400
     line3   300

Now, when I use summary for group#1, I should get 3000 as sum of group amount. but it shows me 11000 (4X2000)+(3X1000) because it sums invoice lines!
what should I do?

Answer 1

You should have running total that is placed into your 'Group Footer #1'

If you right-click and select 'Edit Running Total' you should have the following:

• Field to summarize should be your value you wish to sum. I guess this is correct!
• Type of summary - should be sum
• Evaluate - 'For each record' should be selected.
• Reset - 'On change of group' should be selected and Group #1 should be chosen.

Update In this case if the summary data appears in the source data and you a total for the whole reports change the running total to only evalute for each invoice (Group #1) and don't Reset.

Note: Assuming Group #1 is on Invoice Number and the summary required is for the whole report

So the steps will now be:

• Field to summarize should be your value you wish to sum. I guess this is correct!
• Type of summary - should be sum
• Evaluate - 'On chnge of group' should be selected.
• Reset - 'Never' should be selected and Group #1 should be chosen.
