Field help (PYM)

The code of the pyramid will be used later on in all the reports.

The first group of the pyramid being created is arbitrarily named "GLOBAL".
It is possible to rename this group after its creation via the function dimension groupes.

The levels of the pyramid can be set up in the ascending order from the most general to the finest level.
It is possible for example to define levels from 10 to 10 in order to later include an additional level.
