Understanding the Source Code

Former Member — Tue, 03 Jan 2006 09:36:51 GMT

Hi All,

Pasted below is the Source Code of a Conversion Routine(CONVERSION_EXIT_ABPSP_INPUT).Can anyone tell me the fnctionality of this code.

Thanks

Sajan.M

if flg_exists_abpsp = '?'.

call function 'FUNCTION_EXISTS'

exporting

funcname = 'CONVERSION_EXIT_KONPR_INPUT'

exceptions

function_not_exist = 1.

if sy-subrc <> 0.

clear flg_exists_abpsp.

else.

flg_exists_abpsp = 'X'.

endif.

check flg_exists_abpsp = 'X'.

call function 'CONVERSION_EXIT_KONPR_INPUT'

exporting

input = input

importing

output = output

exceptions

not_found = 1.

if not sy-subrc is initial.

MESSAGE E021(ABPS) WITH INPUT RAISING NOT_FOUND.

endif.

endfunction.

Hi!

This function calls the conversion exit CONVERSION_EXIT_KONPR_INPUT - in case this exit exists.

Regards,

Christian

Hi Sajan,

This piece of code is,

first, checking if there exists a FM 'CONVERSION_EXIT_KONPR_INPUT'.

After ensuring this FM is existing,

It is calling the FM 'CONVERSION_EXIT_KONPR_INPUT' to convert KONPR into internal form.

Regards,

Raj

Hi Sajan,

Your Code flow will be something like this...

1) It checks whether the Flag flg_exists_abpsp = '?', If it is true..

2) It executes the FM FUNCTION_EXISTS and checks whether the FM 'CONVERSION_EXIT_KONPR_INPUT' is exists in your repository or not?

3) If it exists, then the Flag flg_exists_abpsp = 'X' and it will executes the same conversion routine.

Thanks,

Hi,

Thanks for the inputs.

This is one other code that its drilling down into, i.e the "CONVERSION_EXIT_KONPR_INPUT" program.

Will be helpful if you can let me know if you can let me know the pseudo code to understand the functionality.

actually

it is checking for flg_exists_abpsp = '?'

if it so then

it is calling the FM

CONVERSION_EXIT_KONPR_INPUT

and getting the exception as 1 it function does not exisits

if that function exists

it is clearing the flag and coming out of the code

else

setting the flg_exists_abpsp to 'X'

endif

then after checking whether it is X or not .

if it is X then only it is calling the FM

CONVERSION_EXIT_KONPR_INPUT

with parameters

What I can understand from this is

if flg_exists_abpsp = '?'

then FM is going to be checked whether it is existing or not

Could u tell me what the functionality of the FM that is being called inside this program.

Re: Understanding the Source Code

This FM converts the internal code for a WBS element

into the external code.

The input is always a numeric value (8 chars) and output is the WBS code that you see for instance in CJ03 (master data display). Exact coding depends on mask (tcode OPSJ), but can be for example like: A.AAA.1022999

Kind regards,

Hi Raj!!

I don't know if you can help me wiht that

I need use the FM CONVERSION_EXIT_ABPSP_OUTPUT, but in my BW (version 3.1) not exist the FM CONVERSION_EXIT_KONPR_OUTPUT.

Do you know can I do?

Thank.
