How did you connect two sets of conductors to the load side of the 200 amp CB?

Is the breaker listed for 2 wires in one lug? See 110.3 B
The devil is in the details::: As asked, what size wire, how did you connect them to the breaker.
How long is the run and how do the (2) runs terminate (main breaker or fuse)
I'd say 75% + of the times this is done there is one or more Code violations.

Does each feeder qualify under the tap rules?

The double lug is fine as you are installing tap conductors to each panel which requires a main CB. The wire size #2 Al is only good for 90 amps as tap conductors so you'll need to use #1 Al.
That’s true but in RI they let you use 2 al for 100 amp service, I thought the tap rule would cover this it’s less ten 10 feet. The inspector pass the service and on the finish he said no, think him and the home owner had a few words and we were caught in the middle just trying to find code that would pass this again

100 amp service and the tap rules are not the same. A 100 amp service can use the 83% rule which would allow #2 Al for the service. The tap rules require a 100 amp or larger conductor.

If that rule is the same as the one in the NEC, you can't use it for two panels as it only applies to the conductors that carry all of the dwelling unit load.

You don't have a (or two) 100 amp service(s); you have one 200 amp service.
I know I have a 200 amp service feeding 2 100 amp service. One 100 amp service is being fed from behind the meter can. The other 100 amp service is fed from meter can out from the side on the building and goes about 6 feet then goes into thr building to the 100 amp service.

That's what I thought of , too. That's why I agreed with Poweranytime post 14. That is such a common mistake especially in mid central west Indiana. I see it every where, Brand new inspections of buildings. Even the inspectors are not catching it. It's so crazy.

No. You now have (1) 200A service with (2) 100A feeders/subpanels. Different items have different rules.

Yes the terminology is critical in getting the correct answers.

If you can't splain it a picture is worth a thousand words or we'd just be calling inspectors telling them what we did. No site visit just the honor system.lol
