Why do I receive EDH Reception Approval documents from different sources?

The EDH Reception Approval document is automatically generated and sent in the name of the Reception service for orders designated 'manual' where the goods are received by Reception.  These manual orders require a 'qualitative' reception by the technical contact (to ensure the quality is accepted and not just the physical goods).

The same format EDH Reception Approval document is generated by Accounts Payable for manual orders which have not passed through reception but an invoice has been received (typically for services). 

In addition, for all orders (manual and automatic), if there is a difference between the invoice and the orders (for example charges exceed the order), Accounts Payable will also initiate the EDH document or re-route the existing document.
