I need a search help for my bukrs field. The problem is data should come from different system. There are 2 systems like X and Y. i am in X system and running a program.
At selection screen bukrs field exists. When i click on search help data should come from system Y.
I heard that it is possible to pull data to search help but couldn't find enough info in sites.
Best Regards.

To create a search help with a custom data selection, you can define a search-help exit in your search help. To select data in a custom way and not from a database table, go to the tab "Definition" of the search help, remove the content of the input "Selection Method" and enter a function module into the input "Search help exit". This function module must have the same signature as the example module F4IF_SHLP_EXIT_EXAMPLE. The comments in the sourcecode of this example module will explain you how to implement it. Your implementation of this function module can then perform the data acquisition from another system with a remote function call.
To get data from another system, you have to call a function module in a remote system via RFC (remote function call). To do this you need:
the RFC-capable function module in the remote system which exports the data you need. You can set a tick on the properties tab of a function module to make it RFC-capable.
An RFC connection from the local system to the remote system. RFC destinations can be created and configured with the transaction SM59.
To call a function module via RFC, you just have to add DESTINATION [rfc-destination] to the function call.
CALL FUNCTION 'Z_YOUR_RFC_CAPABLE_FUNCTION_MODULE'
DESTINATION 'my_rfc_destination'
IMPORTING [...]
The user will have to log into the remote system in order to call RFC function modules in it, unless you define a username with password in the RFC connection. When you do that, you should create a dedicated system user in the remote system with minimal permissions especially for this RFC connection. When the user has too wide permissions, the RFC connection can be abused for other purposes.

I was asked by the IT Department to write an ABAP program that switches the profile parameter login/server_logon_restriction from 0 to 1 and back automatically triggered (time etc) on all of our SAP servers.
I am not very familiar in the SAP environment yet and until now I managed to get the wanted parameter by using:
RSAN_SYSTEM_PARAMETERS_GET
and
RSAN_SYSTEM_PARAMETERS_READ
But I cannot find anything to change and save them dynamically. Is this even possible?
Cheers, Nils
login/server_logon_restriction parameter dynamic so you can change it via cl_spfl_profile_parameter=>change_value class method.
You can configure background job for automatically trigger it in t-code SM36.
The method don't save the given value to profile file, so the parameter turn back profile value after system restart.
Current logged-in users can continue to use system. May be you can want to inform them with TH_POPUP function then kick from the system.
I was trying to invoke BAPI_MATERIAL_DISPLAY functional module from SAP JCO, This is how i pass my input parameter.
function.getImportParameterList().setValue("MATERIAL", "10");
From my program output i got
The material 10 does not exist or is not activated.
If I execute BAPI_MATERIAL_DISPLAY using SAP logon, iam getting the entry. Using debugger I found that,
My input is going as 00000000000010. And so returning response.
Dunno, how to handle this in a proper way in SAPJCO.
I had directly passed the value 00000000000010 from SAPJCo and this time i got an error,
com.sap.conn.jco.JCoException: (104) JCO_ERROR_SYSTEM_FAILURE: Screen output without connection to user.
Hope SAP is opening a popup. Let me know how to solve both the issues in SAPJCO
Field Material has a conversion exit routine. See also its domain MATNR in the DDIC.
These conversion exits are always called automatically by SE37 but not when the Remote Function Module is called directly - like here from outside from a a JCo program.
So if the BAPI expects to get certain parameters in their SAP internal representation format (I don't know if this is the case here), then you have to do this data transformation on your own beforehand, either by doing this purely within an own routine at Java side, or by calling the appropriate conversion routines at ABAP side via RFC.
For more details on this I recommend to study SAP note 206068.
Regarding your second question with the error message "Screen output without connection to user", I guess that this BAPI expects to have a connection to an SAP GUI for displaying the selected data. With a remote function call you don't have a SAP GUI connection by default, but you can attach a SAP GUI to your RFC connection with JCo, namely by specifying the additional logon parameter jco.client.use_sapgui=1. For this to work, an SAP GUI frontend (either for Windows or for Java) also needs to be installed on your host where JCo is running, of course.
I can connect as user "foo" with password "bar" via SAP-RFC from my machine to the SAP server.
Is introspection possible via SAP-RFC?nI would like to know which methods user "foo" is allowed to execute. I am using PyRFC, but AFAIK this should not matter for this question.
According to user Suncatcher it is not available out of the box.
My SAP knowledge is limited up to now. But wouldn't it be possible to loop like this pseudo code? (This code should run (as ABAP) inside in SAP and could be exposed via RFC)
user = 'foo'
allowed_methods = [] # empty list
for func in get_all_functions_which_are_exported_via_rfc():
if not check_if_user_has_permission_to_call_rfc_function(func, user):
# not allowed
continue
# user is allowed
allowed_methods.append(func)
return allowed_methods
I would like to know which methods user "foo" is allowed to execute.
There is no such entity as method in terms of SAP authorization concept, so you cannot list allowed methods.
You only can get list of assigned roles for your user from the table AGR_USERS (if you have permissions to read it :), and then try to determine which function modules, tcodes, programs you are allowed to call. As we a speaking about RFC, I assume you are interested in function modules.
But the detection of all available RFC-enabled FMs requires separate and not very simple development.
So the answer is NO. You cannot list them out-of-the-box.
Could you explain what is the usage of Modules with select query?
For example if I write (as shown on this page https://cumulocity.com/guides/users-guide/administration/):
select * from MeasurementCreated
Is it useful to get real time notifications by subscribing of the related channel? Is the module reachable by an angularJs Module? Can this module be used in other CEL statements?
Just selecting data without putting it into another stream can make sense in the case you want to make this data available via a real-time channel to some external application (this could be of course AngularJs).
Take a look at this section in the docs: http://cumulocity.com/guides/reference/real-time-statements/#notifications
This very one example though does not make a lot of sense because raw measurement data is already provided on a real-time channel

As for the second part of the question:
Yes it is possible to communicate with other modules within your tenant.
e.g. You can declare some stream in module a and it will be available in module b.
I've copied two Function Modules QM06_SEND_PAPER_STEP2 and QM06_FM_TASK_CLAIM_SEND_PAPER to similar Z* Function Modules. I've put these FMs into a ZQM06 Function Group which was created by another developer.
I want to use Transaction SCC1 to move my developments from one client to another. In transaction SE01 Transport Organizer I don't find the names of my 2 function modules anywhere.
How can I find out the change request with my work?
I copied the FM in order to modify functionality and I know FMs are client independent.
Function modules, like other ABAP workbench entities, are client-independent. That is, you do not need to copy them between clients on the same instance.
However, you can find the transport request that contains your changes by going to transaction SE37, entering the name of your function module, and then choosing Utilities -> Versions -> Version Management from the menu.
Provided you did not put the changes into a local package (like $TMP) the system will have asked you for a transport request when you saved or activated your changes, that is, unless the function group is in a modifiable transport request, in which case it would have created a new task for your user under that request which will contain you changes. To check the package, use Goto -> Object Directory Entry from the menu in SE37.
Function modules are often added to transports under the function group name, especially if they're new.
The easiest way to fin dhte transport is to go to SE37, display the function module, and then go to Version Management.
The answer from mydoghasworms is correct. Alternatively you can also use transaction SE03 -> Search for Objects in Requests/Tasks (top of the transaction screen) -> check the box next to "R3TR FUGR" and type in your function group name.
