Screening Sales Order only and Ignoring Delivery

Summary:

In the EBS-GTM integration, what if we only integrate sales orders and ignore deliveries?

Content (please ensure you mask any confidential information):

In the EBS-GTM integration for export, the common way is to integrate and screen both orders and deliveries. Somehow my client finds it confusing to have two GTM transaction lines representing the same set of data (order line and delivery line). What they proposed was to only screen orders until ship confirm. We examined all cases off our heads, including normal case, cancellation and back order. All cases appeared to be ok by screening order only.

Question: Is there any pitfall for above thought?
