cognos - Use summary data in row calulations on a report? -


i using cognos report studio 8.4.1.

i have list report want use query calculation create new column of data, calculation needs 2 numbers summary (subtotal) of data want calculation for. possible? if so, how do it?

sample data:

id #    project #    reg     ot    bonus     2716    20130405     41.6    1.6 2716    20130412     38.9    0.0 2716    20130419     52.3   12.3 2716    20130426     47.0    7.0 2716    b03-1304                   $23.17 2716    b15-1304                    $1.51 - - - - - - - - - - - - - - - - - - - - - 2716                  4            $24.68 ------------------------------------------ 2717    20130405     39.9    0.0 2717    20130412     40.2    0.2   (etc)

the query calculation want create each line be:

[total(bonus)] / [count(reg)] / (reg) / 2 * (ot) (this not work)

so in above example, result first row of data be:

24.68 / 4 / 41.6 / 2 * 1.6 = 0.12 (rounded)

is there any way can this, or equivalent?

completely re-writing report or creating new report fine. if answer complex (or uses sql), please detailed; i'm novice user , entirely self-taught, there large number of gaps in knowledge of cognos.

you need use cognos summary functions
report studio summaries
or more detailed explanation in here:
using @ , options relational summary functions
question, think should this:

total([bonus] [id])/count([reg] [id])/[reg]/2*[ot] <br>

if reason, not give expected results, try break expression smaller expressions (like total([bonus] [id])) , see if gives expected results.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
