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).
