Order of dimension characteristcs

Posted on Nov 25, 2004 at 12:42 PM 11 Views

does anyone know how to arrange the order of the dimension items in the correct order.

so far I have tried this by assigning the characteristics to a temp dimension and then assigning them again to the correct dimension in the wanted order. this does result in the correct order in the dimension table.

I have tried using the graphical assignment tool, then it looks OK, but the table has again the characteristics in the wrong order.

Thanks Gert

    Hi Gert,

    you define the order of characteristics by the order you take over the characteristics into the InfoCube. So even before defining the dimensions you'd have to know the right order and include them in the InfoCube in this order.

    Regards, Klaus

    Yes - the order in which the char are added to your cube control the order in the dimensions, with possible excpetion of compouned items, which might require you to drag a char back out and then back in if you want it to occur after it's child.

    Curious as to the motivation. Is this putting more selective characteristic first in the dimension (after DIMID) so that the DIM table is accessed via the index that is built on the SID values rather than a full scan?

    I am in the middle of some cube redesign right now and am looking at the order of chars in the dimension tables. This looks like it would eliminate a need to build some of the secondary indices we have on some of our dimension tables. Is that your thinking too?
