Not quite sure what you mean here but if you are trying to ask what I think you are then you are attacking the subject from the wrong way round.

Ratther than learn what everything does (and that's almost an impossible task unless you have a memory that remembers things like railway timetables by heart) you need to concentrate say on a business process --for example SALES and then go through the SAP processes you need to model the business function. This way you'll soon find out the parts of the SAP system which you need and can use directly, other parts where you can use pieces of the SAP system as supplied, and parts which you'll have to build yourself.

It really is no point to know what every function module, class, table etc does in the SAP system if you can't even begin to relate that to a business process whether it's a simple sales / financial process or a complex portal application.

SAP documentation in general is not very good and is almost out of date by the time it appears anyway.

Hi,

Most of the standard Function moduels have documentation.

You can search for FM's in transaction SE37 or SE84.

Once you open the FM inSE37 there is a button Function module documentation.

Well -- have you ACTUALLY tried doing this. Most of the time you'll get a SAP message "Document Function module name in Language EN (or whatever) doesn't exist.

(Some of the newer fmods do have some documentation as well as the BAPI's but great swathes of the old FM's don't).

That still also doesn't relate to the original point --there isn't any point in learning what all these do --you are simply wasting "Brain Power and capacity".

It's much better to find out when you've got real problems to sort out or processes to analyze.

That's one of the HUGE differences between experienced developers and relative newbies.

With SAP there really is TOO MUCH info to absorb totally - especially in a short time.

Pick your area and just go through the forums, google, use colleagues etc etc.

The fact that i might know what a quantum computer is or that function module xxxxxx is used in say the PP module won't make me per-se a better devloper.

All FM exist in table TFDIR.

For the documentaion and usage purpose can access TX SE37.

But for most of them there is not Documentation is given, therefore, try to search it on https://services.sap.com or look for the where use list and try to know about them.
