FUNCTION_CREATE

Former Member — Mon, 14 Jan 2013 10:48:53 GMT

Hi,

I have to create code dynamically at runtime. So I'm going to use the function 'FUNCTION_CREATE' .

Assume the FUNCTION-POOL Z_FYN_FUNC_TEST exists, but the pool is empty - no functions, no types ....

My code looks like:

DATA: include TYPE RS38L-INCLUDE,

code TYPE STANDARD TABLE OF char255.

" First time

CALL FUNCTION 'FUNCTION_CREATE'

EXPORTING

funcname = 'Z_FUNC1'

function_pool = 'Z_FYN_FUNC_TEST'

short_text = 'Lalala'

IMPORTING

function_include = include

TABLES

" it doesn't matter, since the function does not receive any data or

" create any data ...

" Create code, so it looks like

" FUNCTION Z_FUNC1.

" *"--

" any_syntax_error_free_code

" ENDFUNCTION.

INSERT REPORT include FROM code.

" the call processes successfully

CALL FUNCTION 'Z_FUNC1'.

CLEAR code[].

" Second time

CALL FUNCTION 'FUNCTION_CREATE'

EXPORTING

funcname = 'Z_FUNC2'

function_pool = 'Z_FYN_FUNC_TEST'

short_text = 'Lalala'

IMPORTING

function_include = include

TABLES

" it doesn't matter, since the function does not receive any data or

" create any data ...

" Create code, so it looks like

" FUNCTION Z_FUNC2.

" *"--

" any_syntax_error_free_code

" ENDFUNCTION.

INSERT REPORT include FROM code.

" Runtime error like The Function 'Z_FUNC2' could not be found "

CALL FUNCTION 'Z_FUNC2'.

Any idea ?

Kind regards

Ralf

At minimum you need to check for exceptions (sy-subrc). When I can't figure out how an FM should be called, I usually use 'where-used' and see how it's done in other programs.

OK - I forgot to post in the code above the sy-subrc-check (this code is a reduced fragment). In both cases the function returns sy-subrc = 0, so the code should be inserted in the includes.

The behaviour is always the same. The first dynamically function runs successfully and the next created function-call fails :-(((

Kind regards

Hi,

The first function runs successfully, could you try to insert a WAIT UNTIL 2 SECONDS and then call the second function call. However how the second function returns SY-SUBRC = 0 and does not insert the code. Also include exceptions when you call the function 'FUNCTION_CREATE'.

Let me know if any info is required.

Thanks,
