Part 2: Transactions with Account Holders: every value in the cells it covers must be zero or more (SR808.06.08.02, Bank of England check boe_b1103_s)

A warning on the part 2: Transactions with Account Holders template (SR808.06.08.02), in the excluded activities and prohibitions (RFB008) return.

Line4 Check does not run it on the excluded activities and prohibitions (RFB008) return. Held back, never run on a test file. It never runs on any test file of the return, so it cannot be proven yet. It is held back until it is proven.

Check your RFB008 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.
