RFC Function module's where used list

Dear Experts,
I have a situation where in I need to change certain parameters/ the logic of an RFC function module. but before making the changes to the function module I need to know where this function module is used in various systems. So can some one tell me a way to find the where used list of an RFC function module in the calling system.
Thanks
-Amit

It could be called from anywhere, theoretically, SAP or non-SAP environments.
I hope you can rely on good documentation in your organization to find the potential callers, as each call must have been consciously implemented at some point.
Also check with system administrators who might have a means to study trace logs for information on calling systems.
Thomas
P.S. the hard way would be to just do the change and see who complains later on

Unable to find the RFC function module in the impoting list in IR

HI
I am trying to import a RFC function module from the R/3 system.
I am not able to find the RFC in the list that comes for the RFC function modules that can be imported.
The RFC is present in the destination system and is actiated too
If anyone has and idea why is such a thing happning
Regards
Nikhil

Hi Nikhil,
The Checklist,
1. Check the connection parameter at XI
2. Make sure ur function module is remote enabled
3. Make sure ur RFC exists for the same user, client credentials

Altenative To where used list

Dear All,
Can we have an alternate to where-used button. I want to check whether any table is used anywhere in the application.
I want to do it without any use of where-used button.
Please suggest any standard SAP function module or SAP table which would suggest whether a database table is used.
Regards,
Prosenjit.

Hi Prosenjit.
You can use:
Function modules:
BAPI_DOCUMENT_WHEREUSED:
Where-Used List for Documents
C2_DB_PLFV_ATINN_WHERE_USED:
Where-used list for characteristics in the master recipe
CHVW_BATCH_WHERE_USED_LIST
Or,
GoTo->Table DD02T(System texts)->Selection screen->Type under texts = Whereusedlist.
You can check out which database table relates to your requirement.
Good Luck & Regards.

SUP use own RFC Function module

Hello there,
I wanted to create my own RFC Function Module to get a list of purchase orders. So I could use my FM to create a MBO in Sybase WorkSpace. But I've got a problem, whenever I want to add a new MBO and start searching for my own FM, it can't find my Function Module....
How can I use my FM in SUP workspace ?
greetings,
Amintah

Hello,
I have basically the same Problem.
I developed a function module to retrieve maintenance orders from the SAP System.
Therefore I created a package and assigned it to the PM (Plant Maintenance) application component.
Now when I connect to the SAP Server in the SUP WorkPlace, there is only one folder called "Application Components". In its subfolder "Plant Maintenance" I can't find my own function modules.
Do I have to search somewhere else or is there anything else I have to do first?
Thank you for your help in advance!

Debugging RFC function module from ECC to CRM

Hi All,
My requirement is to debug an RFC function module present in CRM(7.0) system from ECC(6.0) system. A report program in ECC will call CRM custom FM. I found many posts in SDN with the same issue and tried to implement suggestions provided there. But I couldn't succeed. The approach I followed is:
I logged in to ECC report program and kept an external breakpoint just before the function module call.
I logged in to CRM system, opened the function module and kept an external breakpoint there.
In both the systems I provided the dialogue userid( id through which I log in to SAPGUI) in the system->settings->debugging option.
In CRM I activated the external break point in transaction SRDEBUG.
Now when I execute the report program in ECC, control stops at the breakpoint. If I press F5 at the function call, control is not going to the external break point set in the CRM FM. I am getting output of FM directly.
I tried with different settings like turning on the check box for IP matching and session breakpoint active immediate, switching to classic debugger etc. I also tried to provide the RFC user id instead of dialogue user but system throws exception saying only dialogue userids are allowed. I found that by inserting an infinite loop statement, control goes inside the RFC CRM FM but I prefer not to change the code.
Please let me know if I missed anything.
Thanks and Regards,
Naren

Hi,
Debug RFC calls
When an RFC function module is called it is usually not possible to debug the call, using the below techniques we can achieve the same. For this example we are calling an RFC enabled FM in ECC system from CRM system.
Scenario 1: Calling a custom RFC FM
STEP 1: Add an infinite loop in the remote custom Function Module (adding a u201CDO. ENDDO.u201D statement at the start of the FM would be enough).
STEP 2: Execute your program in the CRM system. The execution stops at the RFC call, because of the infinite loop.
STEP 3: Now login to the ECC system and go to transaction SM51 select the process which is executing the RFC and navigate to the menu: u201CProgram/Session->Program->Debuggingu201D this triggers the debugger session in a separate window.
Scenario 2: Calling a Standard RFC FM
When we are debugging a standard program we cannot add the infinite loop, hence we cannot go to SM51 and debug the work process. The RFC destination for the ECC system has a User specified, the RFC function module gets executed using this users credentials. Usually the basis team set up the RFC user as non Dialog user, this does not allow debugging. Contact your Basis team and get this changed to a dialog user enabling you to debug RFC function calls via the normal debugger.
Note: User name configured in the RFC destination (transaction SM59)
Note: User type for the RFC User (transaction SU01D)
Hope this will be helpful..

Rfc function module call error

Hi Abaper,
I'm doing upgrade from 4.7 to ecc 6.0 currently and encounter problem in one of the rfc function module that we used. I've tested the connection to destination using sm59 and the connection is successful.
As an information, in the rfc setting, the target system is not Unicode system.
When I test using se37 and put the rfc destination in my function module call, I always encountered system_error exception. There's no issue with this rfc call before in 4.7 system.
Please help me on this. Thank you.
Edited by: Abraham Bukit on Sep 3, 2008 2:36 AM

Hi,
I had the same issue in the past and solved it in the following way.
If the destination system is not Unicode please try to set the password for the communication user set in SM59 using only upper-case characters and taking into account that the password shouldn't be longer than 8 characters.
Hope this will help.

Function Module where-used list does not find update rule programs

We have function modules called in update rules. The where-used list in the function builder does not find the update rule programs.
For example, function DATE_GET_WEEK is called in an update rule to InfoCube YCUBE001. The activated program name for this update rule is GP3PWI6PKM5Y3K75A370DIS8I77. When I goto SE37, enter the function DATE_GET_WEEK, click the where-used button, check the programs option and search. The system does not find the program GP3PWI6PKM5Y3K75A370DIS8I77.
Without this search capability it is difficult to do an impact analysis of changing function modules. Does anyone know of a solution?

hi,
i think the reason is the code of update rules' generated program are stored line by line in table(rsaabap), update rules program itself stored in table rsupdrout, link with field codeid, another useful table is rsupdinfo which store infocube, infosource related. other info may stored in some other rs* and rsa* tables.
try to create following program in your system, and run, type in the function module name, and will display out the update rules program id, with additional useful info : which infoprovider, infosource, and detail info of the routine and infoobject in the update rule that using that function module. you may modify the program to have better display out list.
hope this helps.
REPORT Z_FM_UPDRUL_WHEREUSED.

Function Module to do "Where-used-list"

Dear sirs,
Please could anyone help me? I'd like to know if there is any FM which I can pass the name of an abap object (program, include, table, function module, etc) and returns the where used list of it in an internal table.
I need to map all transactions that call a report or are using an include.
Thank you in advance,
Fabio Purcino

You can use the Function Module
RS_EU_CROSSREF
Read the Documentation of the same.
there is one example.

Function Module "where used list"

I'm looking for a function module which does the same as the where used list: i want to have all tables conataining a special field e.g. mandt. Is there such a FM available?

Hi,
Use FM 'CHVW_EXPLODE_ALL' to get the Batch where used list.

Function Module to identify Where-Used list

Hi All,
Is any one aware of any Function Module(s) to identify where-used list of any given Info Object(s).
I would like to use this in an ABAP Report.
I do not want to use RSD1/metadata repository way.
I was thinking of a way to write multiple selects on the various tables (RSZELTTXT, RSZELTDIR, RSZSELECT...) to get ELTUID/TELTUID/SELTUID..., but that seems to get very lengthy.
Have already checked a few posts but they only indicate the queries/Cubes in which a given IO is used, where as I am interested in all BW objects where a given IO is used.
Thanks in advance,
Sanny.

hi Sanny2 ,
try this method... this will surely help
if you want to know how where used list works then follow the steps.
1 ) open tcode se11
2) enter table name (example...MARA)
3) go to command window (where you often use to enter tcode ... Enter Tcode /h - which is debug switch on)
4) select any field (example .. MATNR)
5) press where used list button.
6) you can navigate to source code (debugger mode)
7 ) follow steps and trace the code HOW WHERE USED WORK,
hope this helps
let me know if useful

Function Module or Program to get where used list

Hi,
I´ve been searching for Function Module or program to get where used list for an object.
I try using the FM 'RS_TOOL_ACCESS' with parameters operation = 'CROSSREF', objectname = 'ZMYPROG', object_type = 'PROG'
and in effect i get the list of object where the program is used, but the list is showed in standard screen.
is there a function or program to obtain the used list for an object but in an internal table?
I'm using version 4.6B.
I checked the function module RS_INFOSYSTEM_CREATE_REQUEST, but i didn't obtain any result, is there a funcion or combination or FM to get the used list?
thanks,
Alejandro

Hi Alejandro,
Please check this sample program.

APPEND P_OBJECT_NAME TO OBJECTS.
OBJTYPE = P_OBJECT_TYPE.
CALL FUNCTION 'RS_INFOSYSTEM_CREATE_REQUEST'

Where-Used List: Modifying SAP standard function module

Hi,
We have decided to modify SAP standard function module SD_SCHEDULING. But before that, we need to understand what impact this modification will have in the system. We will also estimate the risks with this modification.
Therefore, I have taken Where-Used List for this function module. We are aware that this list is not comprehensive.
Do you know any other way we could use to understand better what impacts this kind of modification may have? My colleagues say that this is the only way.
Thanks in advance for your help.
Regards,
Jarmo Tuominen

Hi Jarmo,
Try this
1). Goto Se16 and check the contents of table 'CROSS'.
2). Enter 'F' in the first selection screen field
3). In the NAME field enter the Function module SD_SCHEDULING and execute.
4). The list will give you where all the FM has been used.
Kindly note this is almost the same as doing a where used list. The where used list will only work correctly if the 'Update Navigation Index' works correctly in your system. So just to ensure the result of your where used list you can follow the above steps. This does not require the Update Navigation Index.
Hope this helps
Cheers

Documentation for RS_EU_CROSSREF (where-used list function module)

Hi,
I'm trying to understand how to use the "RS_EU_CROSSREF" function module.
It corresponds to the where-used list function you find in so many SAP screens.
I need to use it in a program, but I can't find any good documentation about it.
I'd like something that tells me what values I have to fill in parameters.
For example, how to search form "TEST_FORM" in all programs ? or even in a given program, I didn't get how to restrict the search to a program...
Thank you for any help,
Quentin

Hi Gurpreet Singh,
table cross does not find any function modules although I know for sure that there are function modules calling the function module.
Please post an example of how to find function modules calling a function module with RS_EU_CROSSREF.
