The rule in plain words

Tier 1 capital (leverage) must be equal to: total exposure measure * leverage ratio.

In each of "LR Exposure: Reporting reference date" (column 0010) and "Daily/Monthly Average over the reporting quarter (LREQ firms only)" (column 0020) of Leverage ratio calculation (LRCalc) (LV47.00.00.01): "Total exposure measure excluding claims on central banks - using a fully phased-in definition of tier 1 capital (leverage)" (row 0290) multiplied by "Leverage ratio excluding claims on central banks - using a fully phased-in definition of tier 1 capital (leverage)" (row 0330) must equal "Tier 1 capital (leverage) - fully phased-in definition" (row 0310).

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark LV47.00.00 as reported.
