Adding dimensions to existing cube in TM1
<p>There are two parts of a TI process that confounds me to no end.</p>

<ol>
<li>This process allegedly creates new dimensions for a cube (using attributes of some element) without a data source. But all I can see is that it creates the dimension name and right away moves on to adding an element to this dimension. How is that even possible, unless someone already created a dimension of that name, which is very unlikely? (Screenshot below)</li>
</ol>

<ol start="2">
<li>This process is also said to add these newly created dimensions to an existing cube. How can that be performed? How will the existing data in that cube accomodate the new dimensions?</li>
