PRA110. Overnight and higher maturity. Significant Currencies: every value in the cells it covers must be zero or more (CL66.02.01.01, Bank of England check boe_b2036_s)

A blocking check on the PRA110. Overnight and higher maturity. Significant Currencies template (CL66.02.01.01), in the liquidity pillar II (PRA110) return.

Line4 Check does not run it on the liquidity pillar II (PRA110) return. Not compiled, as no cell matches what they read. It reads a value that matches no cell of the return’s templates, so Line4 could not compile it.

Check your PRA110 returnWhat to do if it fails

Line4 Check does not run this check yet, so the button checks your return against the Bank's other checks for it. The validation run when you submit includes this one.

The rule in plain words
