RFC access to Function Module metadata

[Former Member]

I'm looking for an API that will allow my program to:

1. Get a list of RFC-callable BAPIs available in my R/3 system.

2. Get all the metadata for a particular BAPI. I.e. the list of all the imports, exports and tables and their descriptions.

Are there standard SAP function modules that perform either of these tasks?

What I want to do with task 2 is generate the logic to call the BAPI within my own GUI, and not require my user to go to the SAP GUI and, say, generate an skeleton RFC C program.

Don't know if there is a standard function module. But you can build your own. You just need to read the FUPARAREF table to get the importing/exporting parameters. And the TFDIR table to check if its an RFC.

hi,

use class CL_FUNCTION_BUILDER_DATA

Here is some sample code to retreive these values from database, implement this code in a custom RFC enabled function module.

report zrich_0002.


data: xattributes type tfdir.
data: isignature type table of fupararef with header line.


parameters: p_func type tfdir-funcname.


select single * from tfdir into xattributes
             where funcname = p_func.

select * into table isignature from fupararef
             where funcname = p_func.


write:/ xattributes-funcname, xattributes-fmode.

skip 1.

loop at isignature.

  write:/ isignature-parameter,
          isignature-paramtype,
          isignature-structure,
          isignature-defaultval.

endloop.
