Create an SAP extraction
You must create an extraction for each document item to extract from the SAP source system.
Create a new extraction for each document item Purchase requisition item and Purchase order item.
Prerequisites
A system integration for an SAP system is created.
A connection to an SAP system is created.
Open a data set, for example, the Purchase to Pay data set.
Click Extractions in the Data set panel. The Extraction section opens.
Click Add extraction. The Add SAP/JDBC extraction dialog opens.
Specify a name for the new SAP extraction, for example, PURCHASE_REQUISITION_ITEM. The name must be unique.
You can specify a namespace for the extraction. By default, the extraction name and namespace are the same, but you can specify a different namespace. The namespace must be unique.
Note that "_ARIS" is not allowed as a namespace.
Select an SAP connection in the Connection drop-down menu.
Click Add connection.

Create an additional extraction named PURCHASE_ORDER_ITEM in the same way.
