What does the You have sent your customer at least one electronic invoice through Ariba Network enablement task mean?

This enablement task appears until you send an invoice to a particular customer through your Ariba Network account. If you see the word Pending next to this task, then you didn't send an invoice to that specific customer yet. This doesn't necessarily mean that they have already sent you a purchase order; it simply means that you haven't completed your first transaction.

After you send an invoice and your customer acknowledges it, the task status updates to Complete.

You might not have the ability to send your customer an invoice until they send you a purchase order. Each customer maintains their own rules and requirements for enablement tasks, so the process might differ for each of your customers.

For additional clarification on why your customer requested certain information, or to determine when they want you to send your first invoice, you can contact your customer directly.
