Summary

Invoice Accounting Coding Notification is not sent to requester

Content

Hi,

Invoice Options => Enable Invoice Account Coding Workflow is checked and  In the the Accounting Preference section, require accounting before approval is selected 

Created a invoice using OCR and from the Scanned infotile, updated the requester information and saved.

At this stage, Accouting Distribution does not exist.

In the ap_invoices_all table, for this invoice, ROUTING_STATUS_LOOKUP_CODE => ORA_AP_REQUIRED

Ran "Initiate Invoice Account Coding Workflow"  ESS job with the Accounting Coding status => All

I was expecting notification would have send to the requested, but didn't come.
