Create condition with PR Purchasing group

Hello all,

Please i need urgent response to this issue. BUS2105 does not have Purchasing Group as part of its attribute, but i need to create a start condition with this attribute (Purchasing group) in my PR approval workflow.

I created this attribute reading from EBAN - EKGRP, but the workflow still does not get triggered when i use the attribute as a start condition.

Please, kindly elaborate on how to achieve this requirement. thanks in advance
