Keeptogether region calculates variable on calc twice

rbuser

I have a report with master data and a detail subreport. In the
detail band of that subreport I have a varialble.oncalc event
that has to accumulate and hence must only fire once.

I now need to keep that mast and detail together - so I put a
region on the master detail band and set keeptogether. However
now, when it has to throw a page to "keeptogether" it does my
subreport.detail.variable.oncalc twice and messes up
accumulation.

A common problem I know of finding an event that really fires
just once, a variable oncalc does - usually.

Can I keeptogether the master and detail without this problem?

Yes, the OnCalc will fire twice in this scenario. However, as long as you
store the value in the variable's value parameter in the OnCalc, then it
will be automatically restored when KeepTogether happens so that the second
time the OnCalc fires, it will calculate based on if the previous OnCalc
didn't take place.

Are you using RB 7.02 for this report?

I am using rb 7.02 ent. The problem is that I am using the variable simply to
fire its oncalc - the oncalc programatically accumulates many non-report
variables according certain criteria.

You'll have to store the values in TppVariables for it to work correctly.
