ABAP Based extractor allows you to use ABAP code as a data source.

To create the ABAP based extractor

Result Structure – SAP table/structure that represents the source structure of data
Target Table HIVE – target GLUE table
Input Structure – SAP table/structure that will serve as a filter for class providing the data - similar to select-options
Class Name – SAP class that implements interface /DVD/GL_EXT_IF_ABAP

Please note: that Target Structure section is automatically generated and its content depends on the defined Input Structure.

3. Save and Activate.

4. The next step is to create a Variant.

Technical details

To use a Class as a Data provider, the class must implement interface /DVD/GL_EXT_IF_ABAP.

The interface contains these methods:

INIT - serves for initialization of required information for extraction process; input parameter is select-options from variant
HAS_DATA - signalizes extraction process, if there are still some data to extract
GET_NEXT_PACKAGE - provides data that will be replicated to Storage
POST_EXTRACTION - post-processing after successful extraction
CLEANUP - cleanup after failed extraction
