Lookahead variable

rbuser

Hi,

Ik have a report with one main table (main report) en 1 subtable
(subreport). They are attached toogether with a LEFT OUTER JOIN so
everything from the main table get displayed, and I only get subreport
where there are values.

My problem is that the "periode date" that I must show in the title
(or header) of the report comes from the subreports.

Report:
Vacation between date A and date B

Department ...
- Vacation info -the periode dates A and B are here


If the first department has vacation records I can use the dates, but
otherwise not...

How can I show it in the begining of the report when it only get
evaluated later?

I have no problem showing it in the footer.

I thoug initializing the variable after pass one or before pass two
would show it correctly but I don't think the title and header are
redisplayed in between?

Is there a way to do this?

Thankx

Chantal

Hi Chantal,

If you are just trying to display a date range rather than a calculation
(grand total, etc.), you might try using a TppLabel rather than a
TppVariable. You should be able to simply update the Label.Caption at the
end of the first pass or start of the second.

Another option would be to pre-process your data and find the date range
before the report prints.

Just what I needed, Using TppLabel works perfect!


Thankx,
