today I found out that besides the verb "to be up to" exists the verb "to be up ON"
While the first means to leave someone decide something (please correct if I wrote this wrong) for the second I can not find a good or proper context. I found on the dictionary that can mean "to be updated or informed" but I m not sure I understand in which sentences can be used.
Thanks

Informed, and aware of the current situation/state of knowledge. Usually used in the negative: I'm not very up on my [area of knowledge].

I imagine I could use "to be up on.." in this kind of situtation:
Some customer calls and asks some info regarding the stand but since this customer is dealing with my colleague I can say him "sorry I´m not up on your project, it´s my colleague who´s responsible for that"
You have the meaning right, but I wouldn't use it with a customer. It's rather informal. You could say "up to speed" perhaps -- also an idiom but not quite as informal.
(Note you have a comma splice: you have joined two sentences together with just a comma. "you project. It's my colleague..." Also, don't leave a space before an apostrophe. It's, not It 's and so on.)
