Hi @TibinM09: I hope you have a page list in the screen. In such case, you can define add button actions to refresh  section and run a Data transform. Tasks in the Data transform as below.

• Get the value which need to be copied to next row in a temp parameter (You can use pagelist(<LAST>) subscript)
• Append a new page and set the property from temp param.

Note: this will work only if you need to add a last row. If your requirement is to add rows in between, then you should have logics to identify the index and write logic based on index.

Thanks.
