reading sourcecode of function modules

Former Member — Thu, 04 Dec 2008 09:14:00 GMT

Hello experts,

I want to search a string in the sourcecode of function modules.

i had already programmed a version for abap programms, but the function READ REPORTS does not accept function modules.

thx for help

The function module is write in an include so u need to transfer the name of the include instead of the name of function.

U can see the name of the include in the property tab in trx SE37

The source code of function modules (in functiongroup ZTST) can be found in LZTSTU01 etc. Includes will be LZTST

Hi,

you need to put in the name of the include

and not the FM

Hi,

As you have to search a string in a FM then it means that you have to read a function module so to do this go to transaction SE37 and then you write the name of a required FM and press the display tab .

then you can easily go through the FM and can search for the required string.

Try to use read textpools ,i think this includes function modules.

okay with include it works,

but I want to scan all* function modules

(* frist I scan the first 1000 only).

can i read the include of some table? The column "include" of the table TFDIR has only numbers but no names.

and how can I get back the name of the function module if I have the include?

Hi,

Use the following FM to get the include name of the function module.

CALL FUNCTION 'FUNCTION_EXISTS'

EXPORTING

funcname = lv_functionname

IMPORTING

include = lv_include

namespace = lv_namespace

str_area = lv_str_area

EXCEPTIONS

function_not_exist = 1.

Now you can use lv_include as the program name in read report.

Thanks, I think that schould work,

but now I understand one of the answears above, with adding an "L" before the name and adding the include number at the end. I think this solution is a little bit faster (´cause there are a lot of function modules to scan)

Yes you're right, u need a code like this:

tables: tfdir.

data: v_include   type trdir-NAME,
      v_funcgroup(30) type C.

parameters: p_func type tfdir-FUNCNAME.


select single * from tfdir where FUNCNAME = p_func.

v_funcgroup = TFDIR-PNAME+4.

concatenate 'L' v_funcgroup 'U' tfdir-INCLUDE into v_include.
condense v_include.

write: v_funcgroup, v_include.

But I'm not sure this solution can be faster than call FUNCTION_EXISTS, because they do the same thing.

Well the results are teh same but the function module FUNCTION_EXISTS has 130 lines of code (minus lines of comments). And at least with direct sql-statements you save 1 function call. It sound not much but SAP has more than 683 function modules.

Okay my programm works.

But im still using "....up to 1000 rows" in my select-statement.

can I say something like: ".....where rownr between 1000 and 2000"? known from Oracle

than I can go trough the database step by step

I believe it can't do it, it can only indicate the max number of hits to be extracted.

I think every time a "SELECT" is open the cursor starts from the beginning.

Try to check the command OPEN CURSOR.

But the good news is, that the number of function mudules is 10% of the the number of abap-reports, so I can go trough in 1 step. (takes less then 10 minutes)
