Dear Experts,

Iam hust going through a SAP Book .in that it is written that there are in two ways we can do enhancement.

Sabiha,

We normally enhance Business Content datasources/extractors by adding an append structure and writing requisite code in the exit.

Though it is possible it is not advisable to modify standard SAP code.

Another possibility is to create a generic datasource/extractor and to do the required coding. Search with 'generic datasource'. There are 3 methods available to create generic extractors - View, Query and Function module.

Practically most scenarios would be covered by enhancing business content supplied datasources with additional fields in the append include or by creating generic extractors.
