I have a report that has current month, quarter to date, and year to date numbers.  I get the current month and year to date numbers correctly but can't figure out what the period code(s) need to be in my column definition to get quarter to date to display correctly.  I've tried adding 3 non-printable columns using Base, Base-1, and Base-2 and then adding a 4th column that adds these together but the numbers are not correct.  We are running CU12 accessing AX 2009 data directly.

Any help on this would be greatly appreciated.
