You would like to comment out portions of code for legacy or future use instead of removing it. Appending # at the front of every line is ugly and messes up the indenting. Here is a quick, neat and simple fix...

Beyond the purely ludic and mathematical aspects of sudoku, this code demonstrates how to set up dimensions, cubes, views, cell formating, security at elements and cells levels all through Turbo Integrator in just one process.

This a short simple syntax to easily pad zeroes to an index value:

Period = 'Period ' | NumberToStringEx(index, '00','','');

Large nested rollups can lead to elements being counted twice or more within a rollup.
The following process helps you to find, across all dimensions of your system, all rollups that contain elements consolidated more than once under the rollup.

TM1 processes will not complain when their input source is empty.
So although the "process successful" or "chore successful" message will popup, your cube will remain desperately empty.
In order to solve that "silent" bug (or Cogglix feature), you will need to add specific code to your TI processes to test against empty sources.
