Hi, You can use "Copy Item" action of Nintex workflow to achieve this requirement, follow the below steps:

• Create a new workflow with "Copy Item" workflow action, configure the source and destination values.



• Set the workflow trigger to run manually, and whenever user want to copy the same item, they go to the workflows and trigger the workflow.

Thanks for the reply. I was also having the same issue.

Thanks again for the help!

Hello all. Anyone get a solution for this. 

Similar scenario. Client would like to be able to copy all the value from a previously submitted Nintex form, change some values that are unique and then submit it to be reviewed. 

Any guidance is appreciated.
