Setup Periods

GENUS's periods table backs every period-aware report and the chartdetails roll-forward. If GL Detail finds a transaction whose date predates the earliest period, the lookup silently maps it to period 1 — every too-early transaction's amount lands in that one month, corrupting the GL.

Use this tool to confirm your periods table covers the full date range of your GL Detail file before committing. The GL Detail commit refuses to run if there's a backward gap.
