BUS1516 workflow doesn't trigger

Hi Everyone,

Need some help on this.

I been creating new workflow for this business object BUS1516.

However, found that Business object box is not ticked and thus the workflow is not being started when created new contract using T-code "REOROF".

Question.

1. Is there any other business object available to trigger workflow to send email once the contract created.

2. Is there any existed workflow available that can modify under this T-code "REOROF".

Thanks,

Regards,

Ethan
