RELATED, MERGE table or none
If you can do it, 2 should provide the fastest calculations because you would want to do that in the Query Editor so there is less work to be done calculating things during display. All 3 will work however.
Sample data though would be very helpful to provide specifics. Please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490
Anonymous,
Just pick columns between mutiple tables may cause some issue or mistabke. So to be general, I would suggest you to merge tables, not use DAX function like RELATED() or RELATEDTABLE() in report level because the DAX engine is much slow than power query engine. All in all, a much more simple and fastest way of data transformation is to do this in database using SQL.

Hey Greg_Deckler
Thank you so much for your answer,
Of course i agree with you that we should attach a sample file in order to have better and accurate advice, but i thought in this case it wouldn't be needed, don't know why, maybe just wanted to hear your opinion.
I've been using option 1 cose i think i've read somewhere that it would be faster, the calculations and the updates. Is this true?
I've tried now to attach a file but i didn't see any option here....let me try again if i can do it after i send this
