I created a Submit Data Connection on Infopath for a Sharepoint List. The Submit Location is the same as the Main Data Connection, however:

-When I use the Main Data Connection to submit, I get an error on submission that the File Name already exists on Sharepoint

-When I use my custom Data Connection to submit, the pop up says the form has been submitted. But the data isn't present in the Sharepoint List.

    How did you customize the list? Via LIST->Customize Form button? How did you set the Submit button? is there any rule on it?

Not 100% sure on the second issue, but the first issue is occurring because Overwriting Existing files is disabled and your filename is being set in a way that however you are filling out the form, result in duplicate names.

One way to easily prevent files from overlapping in name is to include the Date/time in the file name (This is not always the desirable behavior. Depending on the situation, these settings may need to change).

  • I cannot deselect this, since it is the default Infopath Data Connection.

  • Are you able to change the filename?
