Hi @rak95561,
I see you have an exact duplicate of this question here : PDF Mearging in studio x - #5 by Palaniyappan
Please do not post a duplicate of a same question. This is not best practice in any forum. I can assure asking the same question with two different titles will not get you a solution any faster.
If you want more members to help you you can just write a new post in the thread that way the latest feed gets updated to all members and you may get someone attention who knows the answer.
Ask once and follow up on the same thread and you will see more members interact in any discourse forum be it UiPath or others.
