I want to extract the data of the Purchase-to-Pay process from SAP underlying relational database for process mining purposes (https://en.wikipedia.org/wiki/Process_mining). The aim is to come out with an event log that we can exploit to automatically reconstruct the process structure and analyse its performance. I want to be able to extract the main events of the PTP process, for example:
Create Purchase Requisition
Create Request for Quotation
Create Purchase Order
Goods Receipt
Payment
etc.
For each event I need to extract the execution timestamp, the user performing it and the number of the document as the instance id. We should come out with an approach that does not need to be reimplemented for every different customer.
Any suggestion are appreciated!
(I know about Celonis but this is a research effort involving the integration of more information systems, we are not considering commercial options)
