A book may have multiple part like part 1, part 2, total part that can be shown on book cover. How can I add this on title field?

Like this: Abc: Part 1
or like this: Abc Part 1
or Is there other way to use this.

I use: "Title, Part 1"

Olga, isn't there any specific rule for this?

I haven't seen this particular one, but there are examples in the Manual:
Examples of books with the series as the primary title:
My Brain Hurts, Volume One
Gun Smith Cats Vol. 3
Methods of Modern Mathematical Physics, Vol. 1: Functional Analysis

I think Title: Part 1 is incorrect because the ":" symbol separates the title from the subtitle.
"Title Part 1" is probably OK, but I like to add comma.

Since, in example using comma. So I think comma is the best solution in this situation.
