If you've been filing MBRS for a year, you've probably done this.
Last year's XBRL submission was clean. Validated. Client-approved.
So this year, you open the same file, update the figures, check the numbers, reconcile ,- and submit.
It's efficient. It's familiar. It's also one of the most common sources of MBRS rejections we see from even seasoned CoSec firms.
Here's why.
Suruhanjaya Syarikat Malaysia (Laman Rasmi) 's taxonomy is not frozen. Concept tags get renamed, deprecated, and restructured as the MBRS framework evolves. A mapping that was fully compliant in your last filing cycle may silently misflag - or trigger an outright rejection - against today's validation rules. And because the financial figures themselves are correct, the error doesn't show up until MBRS pushes back.
This isn't an inexperience problem. It's a process problem. The carry-forward approach was built for a world where XBRL was stable. That world no longer exists. The right approach is to map every filing fresh - against the current taxonomy, with current validation rules, from the current source document.
That's exactly how IRIS INSTANT 2.0 works. Every filing is AI-generated from your client's PDF, mapped live to SSM's current taxonomy, and validated against today's rules - before the file ever reaches the portal. No inherited tags. No stale mappings. No surprises on submission day.
