Check your file for this ruleWhat to do if it fails

The rule in plain words

In PRA110. Monetisation Actions. Total (CL66.01.01.05): every value in the cells it covers must be zero or less.

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is bigger than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark CL66.01.01 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
