cube FEEDERS issue

Post by nicola531 » Fri Jan 15, 2010 2:48 pm

Hello everybody,

i have an issue with FEEDERS but probably because I haven't understood their proper use.

I have a first cube CUBEA (Dimension1 , Dimension 2, Dimension 3)

I have a second cube CUBEB (Dimension1, Dimension2, Dimension 3, Dimension 4)

The CubeB has a calculation rule in itself so the fast aggregation alogorithm turns off automatically and TM1 Server tries to aggregate all possible cross even if the is a 0 in it.
I would like to find a FEEDER in order to feed the CUBEB from CUBEA.

the CUBEA has the same values and dimension of CUBEB but the dimension 4 because the dimension 4 is from another cube, cube C and to obtain cubA I did CUBEB * CubeC

I don't know how to set a FEEDER rule in CUBE A for all the CUBE B because I don't know what to put in the dimension 4 (I should put a specific value but I what the feeder work for the whole cube)

Is there a way to do it? Is the right way to use SKIPCHEKCS and FEEDERS?

Thanks in advance

You need to have a total element in Dimension 4 - create one if you don't already have one, then feed to it eg
(in cube A)
[....] =>
DB('CubeB',!Dimension 1,!Dimension 2,!Dimension 3,'Dimension 4 All Elements')

thanks for your reply but I'm not sure I got the point.
I mean, I have in Cube B a Dimension 4 tot element and I tried to feed from Cube A to Cube B as you showed me.
It doesn't work, in fact when I go and see the aggregation result doesn't appeare anything at all e in if I go and see the leaf elements there are the vaules.
So it means that the SKIPCHECK in CUBE B is working but the FEEDER in CUBE A not.
I thought that this is maybe because the Cube A only try to feed the Total element and not each element of the Dimension 4. is it?
I should feed all the elements.

Thanks in advance for you reply.

Bye Nicola

Hi Jessy,

You might want to post more detail about what you are trying to do. Basically if you are feeding from a cube with fewer dimensions than the destination cube then you have to make an explicit reference for the extra dimension(s).
Cube A - Dim1, Dim2 and Dim3
Cube B - Dim1, Dim2, Dim3 and Dim4.
In general there are three different ways of feeding from A to B

#Feed a single element in Cube B Dim2
[]=>Db(CubeB, !Dim1, !Dim2, !Dim3, 'An N Level in Dim4');
#Feed a group or all of the elements in Dim4
[]=>Db(CubeB, !Dim1, !Dim2, !Dim3, 'A C Level containing all the elements you want to feed in Dim4');
#Feed where there is a dependency between Dim1 and Dim4 (for example).
[]=>Db(CubeB, !Dim1, !Dim2, !Dim3, Attrs('Dim1', !Dim1, 'Reference to an N or C level element in Dim4'));
