Multiple Years
Adagio's Financial Reporter enables you to report on up to 10 years of stored ledger data using both .ColSpec reports and Adagio Database functions.
To do so using ColSpec reports, simply edit the appropriate .ColSpec cell and prefix the code with {n}. {n} can be an integer from -9 to 9.
For example, if the .ColSpec account data token is Y:
editing the cell to read {1}Y will return the information for one year before the year displayed in the Year dropdown on the toolbar,
editing the cell to read {2}Y will return the information for two years before the year displayed in the Year dropdown on the toolbar,
editing the cell to read {-1}Y will return the information for one year in the future, after the year displayed in the Year dropdown on the toolbar.
To do so using Adagio Database formulas (eg. ADGET), again assume the account data token is Y, simply edit the formula as follows:
to read {1}Y (eg. =ADGET("gldata.{1}Y","$B11") will return the information for one year before the year displayed in the Year dropdown on the toolbar,
to read {2}Y (eg. =ADGET("gldata.{2}Y","$B11") will return the information for two years before the year displayed in the Year dropdown on the toolbar,
to read {-1}Y (eg. =ADGET("gldata.{-1}Y","$B11") will return the information for one year in the future, after the year displayed in the Year dropdown on the toolbar.
Again, {n} can be an integer from -9 to 9.
