Finding the right function modules


When writing ABAP code, I try to utilize the existing function modules as much as possible.

My problem is - how can I locate these function modules? I guess there are several thousands function modules available, and finding the right one - using the Repository Information System (SE84), for example - takes lot of time.

If you need a function module - where do you start? Also, how do you know whether a function module you need does exist at all?

Regards, Jarmo

    Hello Jarmo,

    to find all function modules use the function builder (SE37). To find function modules which SAP declared for public use, you can use the BAPI Explorer with transaction bapi. Also a good starting point is the SAP interface repository:

    There is also the company "VIEW GmbH". They sell a CD-ROM with a SE37 Database where a lot of function modules are described. They also provide example code:

    You can use the SE80 transaction to find which function pools are part of a development class.

    When you debug an application and see it uses a function module, always look at the other function modules located in the same function pool.

    Try also in SE37 to put FI_SEG if you are looking for FI functionnalities regarding items.

    When experienced you begin to 'feel' this kind of things...

      Thanks François for your advise.

      To begin to 'feel' this kind of things it seems that I have to pay more attention to function groups, function pools and development classes also, not just the function modules themselves.
