Hi I am created a workflow for sales order (Custom workflow) which I have created successfully, now I am configuring my workflow and I have to use the field Estimated Margin% in the conditional statement of workflow configuration as shown in the below screenshot

I am using a query that is returning all the SalesTable and SalesLine fields except the fields that are using the display method and this estimated margin is also a display method(OOB) created in form datasource as shown in the below screenshot


How can I get this field in workflow configuration, Thanks.
