Issue in Invoice Background job

Hi,

There is an issue with Background job set up with SDBILLDL program. This job 'finishes' everyday without actually creating any invoices.

After the job is 'finished', In VF04, the list of deliveries are appearing still.  The business then manually create these invoices in VF04.

I have checked the following:

1. the deliveries are OK

2. the Variant is correct. Infact, we use the same variant in VF04 as well

I am not sure, whats wrong with the batch job setting & why no invoices are getting created.

Please treat this as urgent as this is happening in production system.

With best regards

Narain
