How to get Documentation on Funtion Module

hi Experts,
I want to know where can we find the documentation of a FM like for a badi... you can get it from spro..srm...Business add in... where u can click on documentatio....
But how to get documentation fo Funtion module , for example if want to get docs related to FM "BBP_PD_SC_GETDETAIL" how to get it....
Thanks
sameer

Hi. If you go to SE37 and enter the FM name, then press display, there is a button top right called "Function Module Documentation".
It is not maintained for every function though, if the button is greyed out there is nothing. If there is nothing there I do not know if there is anywhere else to look, apart from SDN of course....

Dave.

How to get documentation of a report with its respective headers?

I know fm, SRTU1_GET_REPORT_DOCUMENTATION, has to be used to get the documentation of a report. But when i print out the result it only shows the documentation data and not the data's respective headers. Without the headers the data looses its meaning.
Any idea on how to get both the report documentation and its respective headers.
Any help will be appreciated.
Thanks
Nahman

applicant data also?

Do i understand you correctly that you are not getting the portal event ?
This can be several reasons ?
Both portal system and WDA server has to be in same domain and same proptocol to communicate with Portal event.

How to create documentation of function module while creating function module
Pl tell me step by step process
Helpfule answer will definatly rewarded
Regards
Shashikant

Hi Shashikanth,
go to tcode se37.
before creating a function module we have to create function group.
so to create function group.
chose menu path GOTO -- Function group -- create function group .
give the name of the FG.
again choose menuu path GOTO -Function group -- change group.
give the FG name and select MAIN PROGRAM tab and activate that one.
now create ur FM and click on functiona module documentation button on the application tool bar.
then u will get a PC Editor
in that u will have &FUNCTIONALITY& below this line write ur discription
and for all the remaining options such as &EXAMPLE& &HINTS& &FURTHER_SOURCES_OF_INF&
write ur desired documentation
Then in d application tool bar u will have an icon 'SCREEN OUTPUT' or press ctrlshiftF6.
then u will see the documenation.
Plz reward if helpful,

Hi Faisal
I think your not clear with what i am saying anyhow i will again explain you my requirement
As per my requirement
1)in the service order search report i need to add a field called "Has trail order with No Follow up" with values "Yes" & "Blank"
For above Field i added using the structure CRMST_QUERY_SRVO_BTIL and through configuration i am able to display the field in webui as per (Attachement Pic 1)
2)When i search with search criteria as "Has trail order with No Follow up" with "Yes"
Then in result list i need to show the service order those having follow up as trail orders(sales order) only.if for next document trail order having any follow up then those service orders dont want to show in result list.
For above requirement i implemented F.M using CRMV_EVENT & I configured for BUS2000115 And BEFORE_SAVE The Order
The FM Will get trigger when i save the service order and for that service order if create any follow up and try to save the trail order then This FM Will trigger and in this i am doing validations.
3)Add one AET Trail Flag field is added under CUSTOMER_H Table.
4)in the FM I am validating for if the trail order having the preceding document as service order then i need to make flag as "X" For that service order in customer_h
if suppose when i delete trail order from the service order then that flag must need to be "unset" from the CUSTOMER_H.
Why bcoz we are doing above process is do show records in result list based on Flag values
these flag checks are validating in the BADI Which we implemented for search logic.
Please refer below Login for my requirement:-
Proposal to have a custom “flag” field (background at table level,
     crmd_customer_h) linked to service order which gets flagged whenever at
     least one Trial order is created and saved from the Service Order.
The flag value should be cleared when all the trial orders created and
saved as follow up transactions are deleted from the system.
Similarly for Trial Orders will use the same custom “flag” field
     which gets activated when at least one follow up is created and saved from Trial Order.
The flag value should be cleared when all the follow up transactions from
the Trial Order are deleted from the system.
When the above search criteria “Has Trial order with no follow up”
     “is” “Yes” is applied then the logic derives all the service
     orders which satisfy additional search criteria applied in the search and
     for these Service orders checks if the custom flag field is checked to
     derive all Service orders which have Trial order. The custom flag values
     values are derived from crmd_customer_h table in CRM.
4 )Further for all the Trial Orders determined in Step 3
check if the Trial Order has a follow up by checking if the custom flag field
is checked. The custom flag values are derived from crmd_customer_h table in
CRM.
5) If step 4 is not met populate the preceding Service
Orders in the Result list

How to create a funtion module as i need.

How to create a funtion module, that which should retrive mutiple data with out using data structure.
i.e..using internal table i need to get only some data.
Example:
 1) Using MARC table, i need to get fields only with data (werks, matnr, mmsta, pstat).
i.e importing : werks.
 exporting: werks,
 matnr,
 mmsta,
 pstat.
 2) Also i need coding to get data by without using internal table with the only fields i want.

Hi,
You can only create function modules and function groups using the Function Builder in the ABAP Workbench. For further information, refer to Creating New Function Modules. This section uses an example to illustrate how a function module is created from the point of view of ABAP programming.
Function Groups and Function Modules:
Firstly, we create a new function group DEMO_SPFLI to hold the function module. Then, we can create the new function module.
Parameter Interface:
You can specify the types of interface parameters in function modules in the
same way as the parameter interfaces of subroutines. Since function
modules can be used anywhere in the system, their interfaces can only contain
references to data types that are declared systemwide. These are the elementary
ABAP data types, the systemwide generic types, such as ANY TABLE, and types
defined in the ABAP Dictionary. You cannot use LIKE to refer to data types
declared in the main program.
Exceptions:
Our function module needs an exception that it can trigger if there are no entries
in table SPFLI that meet the selection criterion. The exception NOT_FOUND
serves this function.
Source Code:
Having defined the parameter interface and exceptions, we can now write the
source code of our function module. To do this, choose Source code in the
Function Builder. This opens the ABAP Editor for the include program
L<fgrp>U<xx> (see Function Groups). This is the include that will
hold the program code for the function module;
Data in Function Modules
You can use the TYPES and DATA statements to create local data types and
objects. The interface parameters also behave like local data objects. In
addition, you can access all of the global data of the main program. This data is
defined in the include program L<fgrp>TOP. To open this include, choose Goto
Global data. The global data behaves like the instance attributes of a class.
The first time you call a function module in a particular function group, the data is
loaded into memory. It can then be accessed and changed by all of the function
modules in the group. The system retains the values until the next time a function
module is called.
Calling Subroutines
You use subroutines for local modularization. Function modules can
also use this technique. The function module that they call are defined in the
corresponding main program.
If you only want to call a subroutine from a single function module, it is best to
define them in the same include program as the function module itself, directly
after the ENDFUNCTION statement. These subroutines can be called from all
function modules in the function group, but for clarity, they should only be called
from the function module that precedes them.
If you want to define a subroutine that will be called from several different function
modules, you can define a special include program for it with the name
L<fgrp>F<xx>.
Raising Exceptions
There are two ABAP statements for raising exceptions. They can only be used in
function modules:
RAISE <except>.
and
MESSAGE..... RAISING <except>.
The effect of these statements depends on whether the calling program handles
the exception or not. If the name <except> of the exception or OTHERS occurs
in the EXCEPTIONS addition of the CALL FUNCTION statement, the exception is
handled by the calling program.
If the calling program does not handle the exception
The RAISE statement terminates the program and switches to debugging mode.
The MESSAGE ..... RAISING statement display the specified message. How the
processing continues depends on the message type.
If the calling program handles the exception, both statements return control to the
program. No values are transferred. The MESSAGE ..... RAISING statement
does not display a message. Instead, it fills the system fields SY-MSGID, SYMSGTY,
SY-MSGNO, and SY-MSGV1 to SY-MSGV4.
Source Code of READ_SPFLI_INTO_TABLE
The entire source code of READ_SPFLI_INTO_TABLE looks like this:
FUNCTION READ_SPFLI_INTO_TABLE.
""Local interface:
*" IMPORTING
*" VALUE(ID) LIKE SPFLI-CARRID DEFAULT 'LH '
*" EXPORTING
*" VALUE(ITAB) TYPE SPFLI_TAB
*" EXCEPTIONS
*" NOT_FOUND
SELECT * FROM SPFLI INTO TABLE ITAB WHERE CARRID = ID.
IF SY-SUBRC NE 0.
MESSAGE E007(AT) RAISING NOT_FOUND.
ENDIF.
ENDFUNCTION.
The function module reads all of the data from the database table SPFLI where
the key field CARRID is equal to the import parameter ID and places the entries
that it finds into the internal table SPFLI_TAB. If it cannot find any entries, the
exception NOT_FOUND is triggered using MESSAGE...RAISING. Otherwise, the
table is passed to the caller as an exporting parameter.

Bhaskar

How to get the "last changed by" for a set of function modules?

How to get the "last changed by" for a set of function modules?
is there any table to get it??

See [this|Re: Date of creation of function module] I posted earlier.
>TFDIR will give you the name of the function group program and the include number.
>E.g. SAPLZFUNCGROUP Include 01.
>From this you can construct the include name: LZFUNCGROUPU01.
>You can look this up in TRDIR to find the creation date (CDAT) of the function module.
In your case, you need unam and udat.

How to get sysnr value in a Function Module

Hi all,
I need to get the sysnr(system number) value of the R/3 system. I execute a RFC function module and need to get the value of sysnr of the system it executes in as a return parameter. Can somebody tell me how to get this value in the function module and return it.
Thanks and Regards,
Pratik

Hello Pratik
The system number has to be defined in the RFC destination. Thus, select on your local system (where you call the RFC function module) the corresponding RFC destination from table RFCDES. In field RFCDES-RFCOPTIONS you will find a string like this:
H=<ip address>,S=21,R=N, ...
S=system number
