Error posting into JDE System

I have generated a service to post data in to the JDE 47 tables. When this service is run manually, and I enter data in to the fields I want to use I have no problem.

When I run a flow service that populates the data structure with the same data I used trying it manually I get the follwoing error:

Insert transaction failed:com.wm.util.Values

Does anyone know what I’m missing in my flow?
