Is it possible to pass data from custom record to another
Is it possible to transfer data from “memo field” in a custom record to “memo field” in another custom record, by considering a button to redirect to the second record.
I’m hardly trying to make it by workflow with set field value with no hope
Workflows mostly work only within a single record (e.g. they’re great for approval processes). It’s possible, but very unlikely, that you can do this via workflow (whether or not depends on how the records are linked as @abbott alluded to). What you’re describing could easily be done via suitescript though, it’d only be like 3 or 4 lines, and I bet there are some salient examples in SuiteAnswers.
