Any Function module or any other way to update/change the Function module's fields ?

ankur_sharma16 — Fri, 20 Jul 2012 07:21:04 GMT

Hello Experts,

I want to update/change fields of function module, say import or export parameter etc. So is there any FM available and if not any way of doing so ?

I am trying to see in debug mode how the change happens, but not getting anything.

Please suggest.

Regards,

Ankur Sharma.

Hi Ankur ,

I think what you need can't be done through any FM .

You certainly have two choices :

1 > Enhancement in FM

2 > create you own Z .

Am asking about custom FMs.

There must be a way, am searching for that way. Else i can make a new copy and replace it.

Hi,

You can do it by Enhancement.There is a option in Menu Function Module -> Enhance Interface.

CALL METHOD obj1->update_parameter

EXPORTING

parameter = par_name

line = '1'

parameter_type = 'I'

changing

param_table = it_or

param_docu = it_doc1

modparam = it_ch

moddocu = it_doc

EXCEPTIONS

ERROR = 1

others = 2

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

i must say...please elaborate your requirement.

why you need to change the parameters of the function module.

come with your exact requirement.

however if it is absolute necessary you can create your own custom function module.

first u need to create a function group in which u will assign that FM.

we will start after Your requirement

Hello Abhishek,

My requirement is, I want to rename the DATA ELEMENT used in a Function Module. And i want to do it programatically. This is not good, but i have to do this.

I tried to debug this but could not find much, only that the method update_parameter of class CL_FUNCTION_BUILDER is used, but i am not getting how to use it.

So, if you can suggest anything, than pls help.

Regards,

Ankur Sharma

cl_function_builder will only create instance of the function module.

it will not change its parametrs.

why r u not creating your own z function module. custom function module will exactly same parameters.

revert back if problem not solved.

Abhishek, I know how to create FM, but as you said create own custom FM to update FM parameters, so i was asking what functionality to write in it.

Suppose i have one custom FM whose import parameter is PARA1 and of type ZELEMENT. Now i want to change this ZELEMENT to YELEMENT.

How to do that ?

ques1: u want to change the import parameter of custom FM. or Standard Fm.

if this is custom FM-- simply create new data element in se11 and replace zelement with yelement.

elseif this is standard Fm then create yelement and then create new FM say Zfm_local and write yelement in its import parameter.

As i have mentioned earlier, i want to UPDATE the CUSTOM FM. And i want to do it PROGRAMATICALLY. User will give the old DE name and new DE name, and that new DE name should reflect into the FM.
