Enhance sorce code in Function module option

Dear Expets ,
          Please let me the advantage of the button - enhance source code in the menu bar of the standard function module.
          Can i write my own logic there .
          I am planning to modify the function module - CK_F_INTERNAL_ACTIVITY_VAL - based on certain condition.
Thanks,
Dev

Hi,
The option mentioned is a part of the enhancement framework provided by SAP to write Implict enhancements
Search for Keyword "Implict enhancements" in SDN and elsewhere to get a brief idea
Using this we can write codes in specific areas of the code as indicated by SAP.
To view these locations -> click on the " enhance source code " button and then go to EDIT->Enhancement Operations -> show Implicit Enhancements ...SAP will highlight the areas where code can be written.
Right Click on the area required->Enhancement Impelemtation -> Create
It asks for a "Enhancement Implementation" as a table control pop-up -> Creata a new one using the "create Icon" and give a suitable name .Your enhancement code will be save under this.
In case you plan to undo the changes,go to the spot created Right Click ->Enhancement Impelemtation -> Undo
Always use the "Where -used list" to analyse the impact of the changes when the function module code is changed and use this "Implict enhancement" only as the last option to edit source code.Implicit options may not always be available for all source codes and at all locations desired.
Hope it helps!
Regards
Byju

ALV sorce codes and function modules

Hi Experts,
Can anyone please send me the ALV source codes,the various fuction modules used in it.
Regards,
Narresh

alv is abap list viewer where in u can eliminate the pain of writing the source code
for all manipulations of data on the list.
u have all predifned sort of keys where u can manipulate by using those buttons....
also u can display the list in grid format...
have a look at the most commonly used alv's in these sites..

Implicit enhancement to a standard function module.

Hi everybody.
I used an Implicit Enhancement to a Standard function module Customized_Message, at the starting of function module.
Code:
ENHANCEMENT 1 ZFK01_ENHANCEMENT4. "active version
If sy-tcode = 'FK01' and sy-CPROG = 'SAPMF02K' AND I_MSGNR = '230' AND i_arbgb = 'F2' AND I_DTYPE = 'I'.
EXIT.
ENDIF.
ENDENHANCEMENT.
The above is working fine, to the condition what i had given above code.
But my question is, can i use a implicit enchancement to a Standard function module(Customized_message).

Yes, but you should also be aware that 'F2' is a configurable message class in the IMG. You should attempt to solve your issue in that manner first.

Assigning of process code to function module

hi all,
please let me know where to go for assigning teh process code to function module. i am unable to get the function module from the process code(we42). please let me know
thank you
chan

In WE42 itself we can assign the process code to a FM.
select new entries.
Enter a process code name & description.
Enter Ur FM in Identification Field.
Now select Processing by Function module in Processing type.
Save it.
For outbound do the same thing in WE41 tcode

Processing code and Function Module for IDOC

hi forum,
i m trying to make a file to IDOC scenario,
the IDOC is being sent to a R/3 system,
for the purpose, in R/3 i need to make a inbound processing code, can u tell me how to make a processing code and link it with a Function Module.......
can u guide me....

sudheer,
If you are using standard idoc then you do not need to create new processing code.
There would be standard processing code available. You need to set input partner profile with processing code.
Let us know which idoc type you are using for inbound posting.
Anyway..TC for Creating processing code is : WE41(Outbound) and WE42 (Inbound)
Nilesh

Process code's function module required for the IDOC Message type PROACT

Hi,
I am trying to trigger an IDOC from ME32K transaction which will carry my Contract agreement details to XI. The IDOC I am using for this purpose is PROACT.PROACT01. But I couldn't find the outbound process code / Function module for the process code associated to this IDOC message type.
Pls help me out....
Thanks,
Ram Kalyan

I checked table EDIFCT for the message type and found this:
Function module Function type Basic type Message Type
IDOC_INPUT_PROACT F PROACT01 PROACT
Oops...I think you are looking for outbound..Ignore

but i dont knw the process code for dat can ny 1 help me to find it?
1st of all how to find da process code if u hav the FM ?
it wld b more helpful if ny1 cld give me the process code
thank u
ashwinee

hai
if u dont have process code r cant able to find process code,
u create process code its very easy.
for inbound, go to

Update was terminated (T-code: MIGO, Function module: L_LK01_VERARBEITEN)

Hello SAP professionals,
I've got the following error message when I ran T-code MIGO(Goods receipt).
    Express document. "Update was terminated" received from author user-id
After I ran MIGO, the system said "Material document 5000000190 posted", but it wasn't.
I checked out T-code SM13 and found out function module "L_LK01_VERARBEITEN" was the cause of the error.
But I have no idea why the function module didn't work properly.
The error detail says as follows.
    Class: BM
    Number: 018
    "Specify at least 1 unit"
I don't know what this "1 unit" refers to.
I will describe below the number range of FI for Goods receipt.
    Document type: WE(Goods receipt)
    Number range: 5000000000 - 5099999999 (now: 5000000021 so doesn't overlap with material document 5000000190)
I would really appreciate any help.
Thank you.

Dear Jürgen L.
I've maintained a weight unit as you said, and I've solved the problem!!
I could successfully post a material document!
I don't know much about WM.
Thank you very much for your help.

Function Module for splitting(field) in CO02 t-code

Function Module or enhancement for splitting(field) in CO02 t-code Need function module for inserting a value in field(Max No of splits) in Transaction CO02

You can use this SAP enhancement PPCO0012 to display your own additional
information on a separate tab page in the production order header. You
can also make user fields avaialble for input, change them, and return
the changes to the order header.

Enhancing Function Module Extractor

Is it possible to enhance an extract structure which is using a function module as an extractor.
Basically I want to extract some more fields which the function module is not extracting. Can someone let me know how to do this.
Best Regards,
James.

hi James,
is it generic extractor or business content ?
if generic extractor, since it's our own, you can add field(s) in extract structure and add code in the function module to populate these fields.
go to transaction RSO2, and you will see the extract structure, use SE11 to 'change' the structure and activate. then add code in function module, use SE37.
if business content, RSA6, choose your datasource and double click the extract structure and click 'append structure', add field(s) with prefix ZZ. activate the structure.
and populate the field(s) via user exit ZXRSAU01 (for transaction data).
hope this helps.
