Item Level Fetch in SAP CRMSM

Hi All,

I am trying to fetch all service order item level values from SAP CRM. log file i am able to see all the values from table. I am unable to add it to the agentry app. when i add the agentry app is completely empty with no tabs.

I am using Service order Object,  service order fetch bapi, service order fetch stephandler, serviceorder fetch steplet.

Should i use "ServiceOrderItem" Object?

I am able to fetch header level values and able to display. Please do help in fetching item level value.

Thanks,

Divya
