PO Validation in WFR with EBS Apps Database

Hello Experts,

using the WebCenter Content 12c setup and want to implement the AP invoice processing Solution.

Here I need to Extract the Vendor/Supplier information from EBS Apps database but getting the Fields error as below

I need to do the PO validation in WFR with EBS Apps Database.

Note: not using the AXF Adapters to integrate with EBS, so not created the views using the script WFR_AP_EBS_Views_Create.sql. please provide some guide how I can do it.

Thanks

Sanjeev
