Hello,
Business Central does support drill-down, but not by double-clicking a printed/PDF financial statement like FRx. Go to Financial Reports, select the Balance Sheet/Income Statement or your custom statement, and choose View Financial Report; in the on-screen report, select the amount to drill through from the financial statement to the underlying G/L account/entries. Microsoft confirms that on-screen Financial Reporting supports drill-through to the original transactions; however, amounts that are purely formula-calculated totals may not drill directly in the same way as posting-account amounts. If you are running the standard Financial Report/Balance Sheet report output (PDF/preview), use the interactive View Financial Report page instead for investigation.
Regards,
