detailed description of Info objects for ERP6 and other NW applications

Hello,

at BI in context with extraction I have to do with all applications of NW and also very often with other third party applics.

But for now my focus is at NW applications ex. application set of ERP 6. If I take a look ( with repository browser )

at a table ex. PA0001 ( for human resources ) I can see the definition of info object means data type, length etc. and a "short

description" of field.

My question is : Where or how can I get a "detailed description" of such "info objects". Is there a library existing may be

with examples to get deeper info ? I tried at Marketplace without any success.

Thanks for your advice.

Regards,

Oskar
