using standard sap archivelink to store scanned invoices and trigger sap AP workflows

One of our customers, have a third party OCR service and scanning. Since, they were not using OCR to the fullest extent. They have now decided to drop the expenditure on a third party solution and just use standard SAP to store scanned AP invoices and trigger SAP AP parked document workflow from the standard OAWD transaction.

Now the customer is aware that, Standard SAP does not offer OCR

Questions:

How do I configure ArchiveLink to store AP invoices and trigger workflows?

Would be nice if someone can give the steps involved. Also, I have access to an IDES environment, how can I configure the above? Please help.

Thanks,

Sukumar.
