Fiori : Unable to get data on list view

[former_member592880]

I am a beginner at SAP Fiori and I'm extending my first application so this might sound like a dumb problem but please help.

I have to get incoterms, payment terms and PO number on the master list of Purchase approval, the po number is getting displayed but the other two do not appear although they are visible in the s2 po details page.

<core:FragmentDefinition xmlns:core="sap.ui.core" xmlns="sap.m">
 <!-- This extension point can be used to add fields to ObjectListItem -->
 <ObjectAttribute text="{i18n>view.PurchaseOrder.purchaseOrderLabel} : {PoNumber} "/>
 <ObjectAttribute
  text="{i18n>view.PurchaseOrder.incoTermsLabel} : {parts : [{path : 'Incoterm'}, {path : 'IncotermLocation'}, {path : 'IncotermDescription'}], formatter : 'ui.s2p.mm.purchorder.approve.util.Conversions.incoTermsFormatter'}"/>
 <ObjectAttribute text="{i18n>view.PurchaseOrder.paymentTermsLabel} : {PaymentTermDescription}"/>
</core:FragmentDefinition>
