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…continue reading →

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. 814continue reading →

Extracting Datasources with the DeltaQ component

In this blog I will give an overview about extracting Datasources with the DeltaQ component to extract Extractors / Datasources from SAP ERP / ECC or Export Datasources from SAP BW / BI and give some tips how to troubleshoot errors that may occur. A Datasource is a set of fields that provide the data for a business unit (e.g. Customer, Material). Datasources are one of the data retrieval mechanisms in the SAP source system. Generally Datasources are used to transfer data from SAP ERP / ECC into SAP BW / BI. Export…continue reading →

Extracting data from SAP BW/BI via Export DataSources with Xtract IS

To extract data from an SAP BW/BI system, Xtract IS suite provides 3 different components supporting the following interfaces: MDX engine: Xtract IS BWCube component supports the MDX engine and enables the extraction of InfoCubes and BEx Queries. Open Hub Services: Xtract IS OHS component supports the Open Hub Services that allow you to distribute data from BW/BI system using Infospokes or Open Hub Destinations. Export DataSource: An Export DataSource enables the extraction of the following InfoProviders: InfoCubes, DataStores and InfoObjects. In contrast to Export DataSources, DataSources are provided to transfer data from…continue reading →

Managing Errors during Delta Updates

After having established a delta process with the Xtract IS DeltaQ component, there are usually only delta updates (update mode D). If a delta update fails, you may use update mode R and fill the Request ID in the setting dialog to repeat a failed delta. If you fail to do so and just execute the next delta update a repetition of the failed delta is not possible anymore as SAP ERP only "remembers" the last delta. This is why we have to design an architecure that suppresses delta updates after a failure…continue reading →
