Processing incremental data load of SAP datasources (extractors) with Xtract QV and QlikView

Incremental data load (delta load) is a very common task when extracting data from SAP, especially when extracting a big amount of data (e.g. transaction data like accounting line items).

SAP delivers business content datasources (i.e. extractors) that can be extracted using the DeltaQ component in Xtract QV. Many of those extractors provide a delta mechanism (Update mode) that is managed by SAP. Executing an extractor in the Delta update mode delivers new, changed or deleted records since the last extraction.

This sample uses the SAP extractor 0CUSTOMER_ATTR (for Customer Attributes) to develop a template to process new and changed SAP data using Xtract QV and QlikView (QVD files).

Activating Datasources in the SAP OLTP System

To be able to extract OLTP Datasources from SAP ERP, you first of all have to activate the relevant DataSources in the SAP OLTP system. After activating the DataSources you can extract data from all the active DataSources using the DeltaQ component.

Thoses steps have to be carried out in the SAP ERP system (OLTP). No SAP BW system is required.
