Hello,
(The Environment is LN 10.3 (a.k.a. fp9) and Tools 7.6 a9 and porting set 8.9a, on Windows.)

I am not experienced in development in environments where the user uses the web interface. I understand that that interface gives the user a smooth filtering possibility on fields, and reqmts related to this is the background to my Q.

I have a development task where the requirement is to detect when the web-UI user changes the web-UI field filter on some field and then do a simple calculation based on the records that are displayed on the user’s screen (can be many pages) after the current filter setup has done its job.

Do you know if there is a way to handle this with traditional tools 4-gl and 3-gl programming? If yes, how? If no, what is the way to handle it?
/Regards Pellus

Infor introduced the improved record selection functionality with FP7 (IMHO). I'm still new to this functionality too, but it is worth a look.

Please check the latest programmers guide. Look up "mark records" in the index; this will give a first quick overview. There are more new functions I still haven't used yet:

- for.each.record.in.view.do(..)
- count.records.in.view()

There's also a new standard-option present (select.all = 47) if you need to mark those records.

Those new added functions may be the key to your requirements on calculating some values on selected records, but I still don't know how to detect (and handle) a changed filter in the script.

Maybe using a button (i.e. "Refresh values") or a special-option is the way to go? This will allow the user to access the calculation function in Worktop, too.

Maybe function sum.records.in.view() can help you with the requirement.
