we will create functionmodules in real time or reusing
exsiting one's in abap and webdynpro abap?

Answer Posted / mudassir

well some FM are for reading a text , sending a mail are
very generic and SAP has provided many such function
modules so we use them,
keeping in view specific customer requirements some FM are
also created in customer name space.

in web dynpro there is a wizard for generating code so a
developer never writes a lengthy code but makes few
modifications once the code is generated. eg component
controller name node names ets are to be supplied.
