iAssets and AME - No LOV for appprover when transfering assets

Hi,

Our client requirement is to have approval based on the responsibility center (cost center). Instead of creating multiple organizations with classification company cost center, I created lookup for the names of approvers and create approver group. I updated the rule for transaction type iAssets Receiving Approval Chain. I also did testing in the test workbench and the name of the approver appears but when I tried to transfer asset there is no available LOV for the approver.

Your help is very much appreciated.
