OIM 11gR2 PS3 Provisioning Entitlement Request using API

We have developed the custom code to generate the Bulk request for multiple users through OIM Request Service API. We are reading csv file and generating the request for each entitlement with corresponding approval.

But workflow policy is not triggering because of below condition rule and if we try same entitlement request from OIM identity console they this workflow triggered and worked fine

Please help me to trigger corresponding workflow policy for each entitlement.

Workflow Policy Rule:

appType[AD User].appInstance[ad].appInstanceName Equal ad

AND

operation Equal Provision Entitlement

Then

workflow Equal default/ADGroupApprovalProject!2.5

Code:

RequestData requestData = new RequestData();
