Hi,

I have several sub-reports that group by the one category. In the main report links to two different sub-reports, which displays "Item 1" & "Item 2" for each category. Since Item 1 doesn't have record under category A, but item 2 does. That's why the reports shows below:

Category                                    Item 1            Item 1 %        Item 2            Item 2 %
A                                                       /                                        12/15               82%
B                                                   20/25                85%            15/18               90%
C                                                       /                                         25/30              88%

                      Total:                     20/25                   85%          52/53                89%

How can I change those no record item 1 under category to test "N/A".. Below is the report that I would it to be displayed:

Category                                    Item 1            Item 1 %        Item 2            Item 2 %
A                                                   N/A                                        12/15               82%
B                                                   20/25                85%            15/18               90%
C                                                    N/A                                         25/30              88%

                      Total:                     20/25                   85%          52/53                89%

What are you using to display the data now?

Is it a formula?

If so can you change it so if there is no data it will show N/A

Hi mlmcc,

I have two formulas below. Then I add a text into the report: total_Y/total.

total_Y := sum({@total_Y});
total := sum{@total});

How do you show the 20/25

Is it like

CStr(total_Y,0) & '/' & CStr(total,0)

If so try this

If CStr(total_Y,0) & '/' & CStr(total,0) = '/' then
    'N/A'
Else
   CStr(total_Y,0) & '/' & CStr(total,0)

mlmcc,

 I think when he said "I add a text", he was talking about creating a text field (containing the "/"), and then dropping the formulas into the text field.

 I have no idea what you get when you use CStr on what I guess is basically a null Sum, because there were no records.  FWIW, based on what he posted, I see no need for the variables.  I'd try using CStr on the formula sums (eg. CStr (Sum ({@total_Y}), 0) and CStr (Sum ({@total}), 0) ).


 rowfei,

 Another option might be to use IsNull.  If the sums are actually null, that might work.  CR will let you use IsNull on a Sum.  I just don't know if that will actually catch the values that you need it to.  The formula would be something like this:

if IsNull (Sum ({@total_Y})) then
  "N/A"
else
  CStr (Sum ({@total_Y}), "#") + " / " + CStr (Sum ({@total}), "#")


 I only tested one Sum for a null, because presumably if either Sum is null, the other will be too, so there's no need to check both of them.

You are probably right about how he does it.  In that case he could just drop the formula into the text box or use similar formulas for the two he drops in now.
