Adding Beer Enhancer to Primary during Fermentation

[Norwaybrewer]

So, I just added 200 grams (7 oz i think) of beer enhancer to my primary after 7 days of fermentation. I only added like 850 grams of sugar when setting the batch because I had less than I remembered, and I filled it with 1 litre of water more (to 22.5 l) than I usually do. I always think it`s too thin and bodyless when I do that.

I am brewing a lager at 12 degrees celsius.

OG: 1.045

Gravity after 7 days: 1.022

Activity in the airlock before I added the beer enhancer.

Has anyone done this before, and what was the result?

Is it reasonable from a theoretic point of view?

Anyone with experience on this topic?
