Purchase Requisition data

Hi folks,

I want to extract the Purchasing Documents (Purchase Reqs and Purchase Orders) into BW. I see that there are data sources (2LIS_02_HDR and 2LIS_02_ITM) for purchase orders. But there are no datasources for purchase requisitions.

Does this mean I have to create a generic extractor for extracting the purchase requisition data?

The PO data comes from EKKO/EKPO and PR data comes from EBAN/EBKN. Is anybody aware of SAP supplied extractors for extracting PR data?

Thank you.
