Can Web ADI be used to submit a Concurrent Program or any seeded import program?

Hello,

Basically created a Custom Web ADI Integrator to populate AP Invoices Table and to run Concurrent Request for AP Invoices Import  Concurrent Program.

The Error:

------------------------------

I tried to define a synchronous concurrent program importer type but I am having no luck.  I keep getting the following error:

"The upload process has completed with errors. Press Close to return to the document and fix the errors.No concurrent import requests have been submitted

No rows uploaded

0 rows were invalid

The import program could not be started. Contact your system administrator.. Parameter 5 from the CONCURRENT_REQUEST import step parameter list 200:CR_500191 has the following error: Attribute 2 must have a valid data type value."
