Specify an account root to be linked to the dimension type that has been set up in the following column.
If a dimension type complies with several criteria, it is the largest criterion that will be retained.

A default dimension type and potentially a default dimension are associated with an account root. This setup is recovered and systematically suggested at the account record level.

An account root can be linked to several dimension types and is not limited to only one character.
The attachment level can then be modified.

For instance:
Let us consider the account roots: 6 DIMENSION TYPE 1 and 641 DIMENSION TYPE 1 DIMENSION XX.
All the accounts starting with 641xx are assigned the "DIMENSION TYPE 1" whereas the accounts starting with 6xx are assigned the "DIMENSION TYPE 1" and XXX dimension only.
