AR Invoice Posting

Good Morning,

We have Epicor setup to automatically generate customer invoices once our goods have been flagged as dispatched. This works perfectly well for 99% or our customers 99% of the time.
However for one particular customer, and not for every product we ship to them, the invoice fails to generate/post.
In order to get the invoices posted a user has to go into FM>AR>GO>Invoice Entry, then create a new group, get, shipments, and pull in all Not Invoiced Delivery Notes.

Could anyone hazard a solution as to what is preventing invoices for this customer from generating. Or could offer insight as to where to investigate what the issue could be?

Many Thanks

Please check

  1. Term Type -> Weekly and Billing Days -> All Days
  2. Order “Invoice When Complete” default

Term time is weekly and billing day is All days (same for every customer)
Order “invoice when complete” default is unchecked, but again this is the same for all our customers

Delving deeper it appears that its certain delivery notes that are failing to convert to invoice.

Was there a final reason you found out on why the shipments weren’t being able to be invoiced?
We are working on automating Invoices in batch nightly. Some Orders we don’t want to be Auto Invoiced. Trying to find a good way to do this. Your issue might help me.
