Extend the structure GLU2 to at least & periods

What causes this issue?

The number of period fields in the structure GLU2 does not suffice in
order to execute the rollup for the period entered.

System Response

You cannot execute the rollup.

How to fix this error?

Extend the structure GLU2 to at least &v1& period fields for each
required field group. You do so using the 'Update GLU2' function
(FI-SL configuration menu -> Environment -> Table installation).
You must enter the desired number of periods (for example, &v1&).
After you have performed this function, you must start the report
RGBCFL00 with all parameters so that all FI-SL programs are
regenerated. However, you should not execute this report if you are
working in a productive system because this could lead to errors.
