Hi Hemal,

SAP works on three tier architecture, DB level, application server and presentation server hence it is SAP R/3.

The application server is where all the data is fetched from DB and all the processing done.

Presentation server is your desktop which has only GUI and you will be connected to application server from here.

Reward points if useful.

Presentation server is basically the maching on which SAP GUI is installed , so to put it simply the machine from which you access the SAP system i.e. your machine. To access data from presentation server you can use GUI_UPLOAD , GUI_DOWNLOAD function modules.

Application server is basically the SAP Server , to access data from this you need to user OPEN Dataset , close dataset , Read Dataset e.t.c commands,

Please refer to the help for each for more info.

Hi,

Files are stored in the presentation server means they are stored in your Desktop system... within the code you will find FM GUI_DOWNLOAD/GUI_UPLOD/WS_UPLOAD/WS_DOWNLOAD to determine the same..

Files are stored in the application server means they are stored in R/3 application server ... within the code you will find Open dataset, read dataset , transfer dataset or close dataset
