How do I get results from 5 different objects on Finish good outgoing certificate???

Finished good Test Certificate needs to be created by fetching data from –

• Outbound delivery

• Sales Order

• RM Chemistry recorded during RM inspection - in RM inspection lot

• SFG mechanical properties recorded after Heat treatment inspection for some semi-finished good - in SFG inspection lot

• SFG mechanical properties recorded after Wire drawing inspection for some semi-finished good - in SFG inspection lot

Till now, I have decided that I will keep "outbound delivery" as an input field on TC printing transaction and with the help of "outbound delivery", I will fetch delivery and Sales Order data.

Please help me in getting the results from multiple inspection lots / tell me how should I do it???
