Service Conttact Question

We have a issue where we are not sure whether the SC line got interfaced to AR as we don't see the line in AR

In the SC form, we can see the below

1. Billing Start Date: 29th Sep- 13

2. Interface Date:  29th Sep- 13

3. Invoice Date : 2nd October-13

Our Current period is Oct-13. Billing Program take default as sys date

Can you give us pointers to understand whether this line is interfaced or not.

However, we don't see this line in interface and AR

Any input will be helpful
