Is there a book or reference guide which teaches the SAP Data Services scripting language ("DSSL") step by step, with examples ?
There are many books for SQL, C, C++ etc, but none for DS. There is a small page on this - http://www.dwbiconcepts.com/etl/23-etl-bods/126-data-services-scripting-language.html But this is not a step by step book.
As an aside, what are the limitations of DSSL ? Is it object oriented ? Does it have data structures ? Can you connect to a database directly with DSSL etc ? Can you send mail with DSSL ? etc.
Thanks in advance.
