Printing PO Using SAPScript

Dear Members,

I am very new to ABAP and I have been asked to develop PO using SAP Script. Though I am able to call the supplier details & PO details in the form, but I am not able to call the materials details & Terms & Conditions in the form.

Someone please provide me the correct inner join code or tell me the website where I can found the examples regarding this.

I have used various database tables like: lfa1, ekko, ekpo & makt.

Waiting for your reply,

Regards,

Nishant
