Perhaps you can say: "I will consider the [*two attached] reports as final since you don't have any [^additional / further] comments. * I swapped the positions of "attached two" as the order: determiner (the) -- number (two) -- adjective (attached) -- noun head (reports) is used in the noun phrase. ^ When we say "since you don't have any comments to offer", it's likely that we view someone as having nothing else to share in the first place. However, you used "final" in your sentence; therefore, I used "additional" or "further" to mean that you are not providing more input beyond your "final" report. I hope this helps.

Hey Niwantha, how are you? I should say that your sentence needs only a few changes. For example, you might say: ''I will consider the two attached reports as final since you do not have any other/further comments to offer/make/provide.'' Hope that helps!!! Please do not hesitate to contact me should you have any further doubts/questions regarding English grammar. I shall be pleased to help.

"I will consider the attached two reports as final since you don't have any comments to offer." Your sentence sounds perfectly natural to me. It can be easily construed though as slightly critical to the person being spoken to if you're not careful. That is, the person being spoken to hasn't made any comment or contribution and they should have. You'd have to be very careful with your tone of voice in delivery. Personally, I'd change "since" to "if" and perhaps make it "more comments" rather than "comments". So, I'd deliver the sentence as : "I will consider the attached two reports as final if you don't have any more comments to offer." But I am assuming the person being spoken to has already made a comment or two, and that you want to be a little more polite.

You just need to change the order of these words. I will consider the *two attached* reports as final since you .... And the rest is okay.
