I have a problem with details values of crosstab, which I want blank if null.
I checked the corresponding option (blank if null) and, at this point, no problem.
But when I set the total as an average calculation, relative null values were replaced with 0 instead of blank.
In my case, this is a real problem for understanding this report !
How could I have a blank value in this case ?
Thanks for your response
You can realize incrementer on java which return null (or your own specific object in terms of java) instead zero
There are few information about realization of such classes in internet and documentation
And this way not for newbies imho
I guess you have choose the easier way. For example you can calculate count not null values on column (row?) of crosstab and hide sum variable if this count = 0
