If you are closely acquainted with ABAP Objects and more generally with OO technology and paradigm, then it is likely that you have your own OO developments you want to reuse. Personally I have some. The problem is that for one reason or another not always you can use SAP transport system to port your classes from one system to another. There is a standard program RWBPRINT which can be used (with debugging tricks) to download ABAP class data, but frankly it is not quite convenient, its strength is that it can be used as a usage template of some function modules for accessing ABAP class data. Why XML? When thinking of file format I had remembered that SAP SmartForms has upload/download functionality which uses XML format. Also I was already familiar with CL_XML_DOCUMENT class which offers DOM model functionality for XML documents. And also I had an idea of utilizing XSLT transformation somehow to make myself familiar with it (unfortunately, there were no need, as SAP function modules for reading and creating ABAP classed have fully compatible parameters which can be converted from/to XML without special transformations). And yes, everybody uses XML nowadays. Usage Download utility Program YRS_CLASS_DOWNLOAD_XML has quite simple selection screen (see below). Selection screen parameters Parameter Type Notes
