Check your file for this ruleWhat to do if it fails

The rule in plain words

In Z0020, hierarchy options 1 to 3 must be reported only during ARS entry point, and options 4 to 5 must be only reported only during ARG entry point

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.

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark IRR.25.04 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
