e way bill

Greetings of the day We are the Event Management company our nature of business is organising events,marriage parties etc. we organise events in other state's . In this case we need to send some materials like stage materials , logistics, set related ( fiber items) etc.. the above said materials are owned by the company. the movement of the above materials just for event purpose not for sales. the materials will get return after completion of the particular event. So my doubt is how to generate the e-waybill in this case ? 

sub type Type would be Own Use/ Others??
