Ritesh,
Thanks for the solution.
Turns out that I did not understood the requirement corectly.
We have variant configuration, so there is one configuratble material that variant.
The configurable material has class 300 and 001.
The request was to have one characteristic with values on class 300 and if if we use the same characteristic for class 001 to have the values there. And that is hapening because the values are assigned to characteristic. so everywhere we use the characteristic, it will carry the values with it.
For any other requests I will consider the note and information provided by you.
Many thanks, wishing you all the best !
