There are extension fields on item level in a purchase order, but when querying the purchase order by API: QueryPurchaseOrderQueryIn, the content in extension fields are not returned in the response.

1. Go to Purchase Requests and Orders work center.
2. Create a new purchase order XYZ (XYZ stands for the document ID).
3. Fill in extension fields on item level.
4. Go to Application and User Management work center.
5. Go to Service Explorer view and download WSDL for API: QueryPurchaseOrderQueryIn.
6. Create a new project in SOAP UI for the WSDL.
7. Input required information in the payload to find XYZ. 
8. In the response result, there is no structure of "<n1:TechnicalName(field name) xmlns:n1="namespace of the extension field”>Value of extension field</n1:TechnicalName>".

This is an expected performance.

QueryPurchaseOrderQueryIn cannot return extension field values on item level, but will return ones on header level.

To get extension field values on item level, user need to call ManagePurchaseOrderIn.
