The rule in plain words
In column "Amount" (0010) of Own funds (CA1) (C01.00.01.01): "(-) Excess of deduction from AT1 items over AT1 Capital (see 1.2.10)" (row 0440) must equal -1 multiplied by "Excess of deduction from AT1 items over AT1 Capital (deducted in CET1)" (row 0740).
The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.
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 C01.00.01 as reported.
