Why?

If you are closely acquainted with ABAP Objects and more generally with OO technology and paradigm, thenit is likely that you have your own OO developments you want to reuse. Personally I have some. Theproblem is that for one reason or another not always you can use SAP transport system to port your classesfrom one system to another. There is a standard program RWBPRINT which can be used (with debuggingtricks) 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 functionalitywhich uses XML format. Also I was already familiar with CL_XML_DOCUMENT class which offers DOMmodel functionality for XML documents. And also I had an idea of utilizing XSLT transformation somehow tomake myself familiar with it (unfortunately, there were no need, as SAP function modules for reading andcreating ABAP classed have fully compatible parameters which can be converted from/to XML withoutspecial 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

Class name Parameter ABAP class name to bedownloaded. Can be selected viasearch help

Show XML file in browser Flag If set, resulting file will bedisplayed in additional window,

Parameter Type Notes

else file open dialog will bedisplayed and file will bedownloaded to the workstation.

Languages for class text pool Select option Restricts set of text pool

languages to be downloadedwithin XML file. If not set then allavailable languages will bediwnloaded

Upload utility

Report YRS_CLASS_UPLOAD_XML has the only selection screen parameter XML file name which can beselected via File Open Dialog invoked by pressing F4 button.

After parsing XML file the utility checks class existence and if successful asks if existing class have to beoverwritten

Versions supported

I tested both utilities (not thoroughly though) on 4.7 and ECC 6.0. As utilities employ OO class exceptionsthey cannot be used on 4.6c, though backport seems to be possible.

Notes

Both utilities extensively use CL_XML_DOCUMENT functionality and also someCL_GUI_FRONTEND_SERVICES class (open and save file dialogs). Also all class data manipulations are

done with function modules from SEOK package (ABAP Objects Class Builder Services).

Weaknesses

Only classes can be uploaded or downloaded (not interfaces or exceptions)

Documentation is not downloaded

Descriptions of class elements downloaded in logon language only
