How to find fuctionality of function modules

Hi experts,
In CRM I have seen some the following function modules
CRM_ORDERADM_H_READ_OW
CRM_ORDER_READ
CRM_APPT_MAINTAIN_MULTI_OW
CRM_APPT_MAINTAIN_SINGLE_OW
CRM_DATES_READ_DB
I could not find any useful Information when using F1 key to know it's functionality description. I will be thankful If you tell me the functionality description of the following functions OR any way in which I can find such description

Hi Murali,
I think the information should be in Germany.
But you can see from its name. For example :
- CRM_ORDERADM_H_READ_OW => is function to read header order document
information.
- CRM_ORDER_READ => is function you can use to read the whole document
content (header + item data)
- CRM_APPT_MAINTAIN_MULTI_OW => is function to read several
appointment (from dates profile) on document
- CRM_APPT_MAINTAIN_SINGLE_OW => is function to read one particular
appointment date on document.
Hope this could help.
Gun.

How to find the Obsolete function module in ECC 6.0

Hi Guys,
How we can find the all obsolete function in ECC 6.0, is any T-code to finding the obsolete function modules, or any other way to find.
Could you please help me.
Thanks,
Gourisankar.

Hi Gouri,
If you are looking at determining whether a single FM is obsolete or not is by this method:
Go to FM in SE37 -> Goto Attributes Tab -> General Data section -> look above the Edit Lock field ... where SAP places the release status and date of the FM, if the FM is obsolete, the text Function Obsolete appears
This is one way of finding out one FM @ a time
However if you want to check on a mass scale, I dont have a SAP system here hence cant confirm, however, all FMs are stored in TFDIR database table. Please scroll through the fields of the DB table to check whether any field relates to release status or the like. If it does, then from SE16, you can put the value corresponding to "Obsolete" in the field and run to check all FMs.
Cheers,
Aditya

How to find suitable( existing) function group for a Function Module ?

How to find suitable( existing) function group for a Function Module to be created?
This is FM for converting amounts to text.

Hi,
If you are not sure into which Function group your FM should go in then its advised to create a Function group of your own. Its not advised to create a function module in any other function group unless its owned by you since your FM can get deleted by others or it can get changed.
Create your own Function group. But if you want to create in an existing FG then best way is to find out the Function Group by searching for suitable existing Function module then see their function group

How to create EXCEPTION in function module

hi experts,
          how to create exeptions in function module i want step by step.
regards,
chaitu

hi,
Raising Exceptions
There are two ABAP statements for raising exceptions. They can only be used in function modules:
RAISE except.
und
MESSAGE.....RAISING except.
The effect of these statements depends on whether the calling program handles the exception or not. The calling program handles an exception If the name of the except exception or OTHERS is specified after the EXCEPTION option of the CALL FUNCTION statement.
If the calling program does not handle the exception
·         The RAISEstatement terminates the program and switches to debugging mode.
·         The MESSAGE..... RAISING statement displays the specified message. Processing is continued in relation to 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, sy-msgty, 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 with MESSAGE ... RAISING. Otherwise, the table is passed to the caller as an exporting parameter.
Calling READ_SPFLI_INTO_TABLE
The following program calls the function module READ_SPFLI_INTO_TABLE:
REPORT demo_mod_tech_fb_read_spfli.
PARAMETERS carrier TYPE s_carr_id.
DATA: jtab TYPE spfli_tab,
      wa   LIKE LINE OF jtab.
CALL FUNCTION 'READ_SPFLI_INTO_TABLE'
     EXPORTING
          id        = carrier
     IMPORTING
          itab      = jtab
     EXCEPTIONS
          not_found = 1
          OTHERS    = 2.
CASE sy-subrc.
WHEN 1.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno.
WHEN 2.
    MESSAGE e702(at).
ENDCASE.
LOOP AT jtab INTO wa.
WRITE: / wa-carrid, wa-connid, wa-cityfrom, wa-cityto.
ENDLOOP.
The actual parameters carrier and jtab have the same data types as their corresponding interface parameters in the function module. The exception NOT_FOUND is handled in the program. It displays the same message that the function module would have displayed had it handled the error.
Hope this is helps,Do reward.

How to create a callback function module

Hi all,
I am working in a requirement where we need to call a function module at a 'after change' event. So how to create a callback function module and register it with the crmvevent ?_
I created a sample function module and try to create entries in table crmv_event_cust, but i got an error message saying that the function module name I provided is not in table CRMC_FUNC_ASSIGN. When I try to create entry there, I got a message that function module is not in CRMC_OBJ_FUNC and that table is a standard table with no maintanance options !!
looks like i am going in wrong way ... can any one please help ??

Looking at my system all you need to do is create the entry for the callback function in maint view: CRMV_FUNC_ASSIGN.
Your entry should be as simple as Z-function name Object Function - <same as others in the segment you are assigning>
IE for the partner it would be CRM_PARTNER as object function, for general order processing CRM_ORDER
Take care,
Stephen

How to check for a function module with its description and functionality

Hi all,
How to check for a function module,with its description and its functionality,in detail how can I know the purpose of a particular function module,how to search for a function module which suits my requirement .

Hi,
You can search a FM of your requirement by putting in the Key words and searching for a FM. Like * KEYWORD * and then pressing F4.
Say for example you need to search something regarding converstion.
Search for * CONVERT * and press F4.
If there is something specfic like converting date to something you can give
DATE * CONVERT *
OR
CONVERT * DATE * and press F4.
Once you narrow down your search you will have a Function module documentation inside the Function module. Please note that all the FMs willl not have documentation.

Pramod
