Hi, guys I want to be sure of something,

If I have a C: element named Income (formed by local, inter and other) this feeder is correct?

SKIPCHECK;

['income'] = N: ['discount'] * .15;

FEEDERS;

['discount'] => ['income']; is ok?

probably i will not have a "not fed", but a C: can feed a N:?

Regards,

Looks fine to me, you can feed from N to C but you'll have trouble if you try to feed C to N.

Thanks Steve, i just wanted to be sure.

Regards,

Hi Rodrigo,

If ['income'] is a C: element than the rule ['income'] = N: ['discount'] * .15 will not return a result, because of the N: prefix in the rule - this will make the rule calculate for N-level elements only. When you change your rule to ['income'] = ['discount'] * .15 the rule will calculate on a C-level (but then regarding all dimensions).

Please note that when you feed a C-level element you're in fact feeding the child-elements of this C-level element, not the C-level element itself. The C-level element will only "be fed" if at least one of it's children has a non-zero value (as you can't really feed the C-level element itself, with "be fed" I mean the consolidated element will f.i. show up correctly in a zero surpressed view).

mmmh big mistake michael i wrote, sure a discount formula was

['discount']=N:['income'] *.15; (30+30+40)*.15= 15 usd discount!

trying to feed with

['income'']=>{'discount'};

i was on a hurry and suddenly i hit some button that moved the screen to another and when I refreshed it was blanked... i wrote it again quickly crossing a nonsense formula. sorry!

does it make a difference from steve[s answer? income is a C: that feeds a N: like discount

Hi Rodrigo,

This rule/feeder looks OK to me.

Hi Guys,
My rule of thumb for writing feeders, seek for the feeder "trigger" (lowest level) , try to avoid feeding C: levels (a big temptation) it's can overfeed the model and damage the system performance.

Hi Rodrigo,

In this case if the discount % is constant and doesn't vary by product/channel then you can do away with this rule alltogether and make discount a consolidation, the child income will have a weighting of 0.15.
