Natural Consolidation to calculate %

[conray]

Is it possible to use natural consolidation to calculate %, such as:
A amount / B amount = AB%

AB%
|_ A amount
|_ B amount

Not in a consolidation; for that you use Rules.

Exception: If the percentage is a fixed amount (say 10%) rather than being stored in another element, you can use a weighting when you add A Amount to the consolidation AB%. If the amount is variable, though, Rules are required.

Hi conray,

You'll have to use Rule Calculations for that.

[conray]

ok understood, thanks for the feedback.

This trick can be used to have numeric values expressed in thousands (or millions):
make a consolidation out of the original value, with weight 0.001 (or 0,000001).
Apply numberformatting and you're done. It saves us from writing a lot of feeders and
therefore, the TM1 model is potentially a lot smaller and efficient.

If you have a separate "scale" dimension in the model using exactly this technique that you add to all cubes as required then this is an even better trick.

You're on Earth, third planet of a yellow star commonly referred to as The Sun which is located in one of the more unfashionable backwaters of the Alpha quadrant of the Milky Way galaxy.

Or if that doesn't answer your question...

Are you referring to weightings in consolidations?

If so, what we're talking about is this. Suppose that you have 5 N level elements in a consolidation, named A to E. By default these have a weighting of 1, meaning that the consolidation's value will be A + B + C + D + E, agreed?

However the weighting doesn't have to be 1; it can be any value. So suppose that you set the weighting for each of them to 0.001. The consolidation's value will then be (0.001 * A) + (0.001 * B) + (0.001 * C) + (0.001 * D) + (0.001 * E).

So supposing that A, B, C, D and E were in millions, your consolidation is now reporting the value rounded to thousands, without having to write a rule to do it or relying on rules functions which are less efficient than consolidations.

Looking at OP's original question I would be lost too if I were OP. He (?) asked about division and we got a (nonetheless interesting) discussion of scaling.

Basically natural consolidation adds. OP wants to divide. The only way for OP to do this with natural consolidations is to add the logarithms of the numbers (with a weight of -1 on the second) and then antilog. This would require a rule to do the log and antilog and is also much complicated by edge conditions (log(0) is -infinity) so why not just divide anyway.

BTW I like the way lotsaram said

that you add to all cubes as required

You must have been thinking of another piece of software - or are you a closet Performance Modeler user ?

What does a weighting of 0.001 do?

Or, since we're talking percentages (or were in the original post), what does a weighting of 0.01 do?

Hence my original "Exception" qualification

Exception: If the percentage is a fixed amount (say 10%) rather than being stored in another element, you can use a weighting

[conray]

okay, so this is what i understood:
1. Alan is trying to explain, that we can round values using weightings instead of applying rounding method directly in rules.
2. There is no direct way to use natural consolidation to do a division.
