Adding more info to PO Approval WF Notification

Question

I’m a newbie at workflow and I have a requirement to customize PO Approval workflow Notification this means Notification will have more information than Oracle seeded notification information, by adding additional information to the notification email that is sent out (such as freight terms etc.).
Having reviewed most of the workflow processes and corresponding packages, I’m unsure in which of the WF process/pkg to implement the change and what steps to follow in order to add /implement it accordingly.
Any guidelines on what steps to follow is much appreciated in advance.
thanks

I believe this is more of a PO question than WF question. PO uses Oracle workflow to route documents for approvals and performs various business transaction to transform the document. Following are some of the ways notification content is generated in workflow.
1. Boilerplate text and message attribute tokens.
The notification content is generally standard with some variable content. Tokens are used for the variable content alone whereas rest of the content is typed into the message body when designing the workflow.
2. Document Type message attribute
The notification content could change drastically based on various business scenarios and recipient of the notification. For such a situation the complete content is being generated using a PLSQL Document Message attribute. The notification body at design time would look like &MESSAGE_BODY which is related to a PLSQL procedure that will generate the complete message.
Now, coming to the PO workflow scenario, the PO approval notifications are generated using a PLSQL Document API within PO_EMAIL_GENERATE package. There are procedures GENERATE_HEADER, GENERATE_HTML that generates the content. You may want to look at these procedures to customize.
Hope this helps
Thanks.
