Refer to the article, can anyone explain more for the following points ? Tks

1. The MDX script take a layered approach to calculations within a cube through the use of calculation passes.

2. A SCOPE statement is dynamic, but not iterative in nature. The statements contained within a SCOPE statement run once, but the subcube itself can be dynamically determined.

1. This means that, conspectually, not everything is evaluated at once. In other words, the cube data is calculated first, and then things such as SCOPE can alter previous calculations. You will see that one of the example increases [Amount] by 10% - but what does it increase it from? It has to calculate an [Amount] first in the cube, before then increasing it by 10%.

2. Exactly what it says. The SCOPE statement only runs once - that means that it can't be iterative (so it can't say that its value is based on its value in a previous calculation of itself). However, the part of the cube that it alters does not need to be fixed - you can have a subcube which is not fixed, but is (say) the 10% of the cube by value, as opposed to saying that it alters the value of [Amount] for the countries of the UK, France, and Germany (which is a fixed list).

Hope that helps.
