Table containing Reporting Currency Period Totals

Is there a table similar to the GLAMOUNTS table which contains the reporting currency period totals instead of the Base Amount totals contained in the GLAMOUNTS table? Does that exist?

For example: When running a GL95 with Type = R Reporting & Currency = USD (in our case), is the begging balance amount stored in a Lawson table for the specifiied account(s) or is the beginning balance calculated at the time of the retrieval? Thanks!
