Default Very Large Parent-Child Dimension - 09-10-2003 , 07:44 AM






Hi,
I have this problem at hand and I hope if someone can help me with
it. I have a P-C dimension with 7 possible levels. Now the problem is,
at some level the 64K parent-child member limit can be exceeded. I
have searched Google KB for this issue and was excited to find some
solutions like using Member Groups, upgrading memory, restructuring to
a regular dimension, VLDMs, and upgrading to the 64-bit version of
AS2000, but non of them seemed "formal" (documented), acceptable or
feasible. Can someone plz give me more insight about this? Btw, I
haven't run into this problem yet, that's breaking the 64K limit and
in some posts some said it doesn't even exist. It's just a design
issue and I want to take care of it before I start building the cube.

TIA
Peter

If you have this many members in a parent child dimension and you know that
you will have at most 7 levels, then I would recommend that you change it to
a regular standard dimension and use the "hide member if" functionality.
You can also use the auto grouping feature to get around the limitation of
only 64K children per parent.

Thanks Sean for your reply, just one more question, and this might
turn out to be a very silly one, but how do you turn on the "auto
grouping" feature for a P-C dimension? A parent-child dimension
according to BOL "is defined with a single level of a special type
that usually produces multiple levels seen by end users". Although a
P-C dimension is by default a changing one, yet the "Grouping" feature
is not even there in its properties. Probably because - and again
according to BOL - "You cannot create member groups in a dimension's
top or bottom level." And since a P-C dimension has in fact only one
level, I guess that level is considered the "top" and "bottom" level.
I also guess in a P-C dimension I can't use the workaround of adding a
"dummy" level. So, am I missing something here?

thx
