 I have created two form library (Form Source & Form Destination )  in SharePoint. Using designer workflow I copied item from source to destination library. I opened the item in destination form library and update some fields in the form once I submitted  form it will create automatically new item in the same form library with updated values. This is continuously occurring whenever edit and submit the form.

How to update the same form using ( custom Rules) submit button Please help me on this topic. 

 I'd guess this has to do with your submit connection - it probably only submits to the source library. You probably need to add another connection to the destination library and in your submit rules, you can determine which to submit to. Is the logic as simple as new forms submit to the source library, and edited forms submit to the destination library? If so - I'd just have a field in the form's data source (not on the form itself) that I set to "submitted" or something prior to the initial submit to the source library. Then you can leverage that for subsequent submits.

 Hi Hilary , sorry for the late reply. Thanks for your valuable input. I have just created filename field in the data source and based on this field I have checked is blank & Is not blank conditions in two different buttons its works fine for me.Now it its updating same form.
