The rule in plain words

Business Indicator Amount cannot be empty

In Operational risk: part 4 - business indicator and subcomponents (OPR) (OF16.00.01.04): "Business Indicator (BI)" in column "Component value" (row 0010, column 0050) must be reported.

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 OF16.00.01.04 as reported.
