Problem calling function module via rfc

Hello,
i have imported an adaptive rfc model.
When i use it on a view, giving the import parameters over a textview and showing the results in a table everthing works fine.
But when i set the input-parameter programmatically with a line like this:
wdThis
.wdGetCompController()
.wdGetContext()
.currentZ_FUNCTION_MODULE()
.setMyAttribute(parameter);
it does not work and i do get no errors - what can it be?
Thanks for help,
André

Hi Andre,
As you told, When you passing the value from the screen it works perfectly.So, there is no problem in initializing Model.
You have to write following code in view and context of this view should be mapped with controller.
wdContext.currentZ_FUNCTION_MODULEElement().setMyAttribute(<value>);
Write this statement before executing your model.

Bhavik

Third party system call function module/BAPI through RFC to update Z table

Dear Friends,
We have a third party system which directly inserts a Z table in SAP through its programming, which is an auditing issue.
We want the third party system should call function module/BAPI through RFC so that the Z table gets updated.
waiting for inputs..
Thanks,
Kumar

if third party system is capable of making Remote Function call, then writing a Function module & making it remote enable is not difficult task in ABAP.
You may have to prepare specifications first to decide if third party system is going to Read, insert, update, delete records from Zee table.

Problem in converting a function module in RFC

hi All,
when i m converting a function module in RFC it is showing a error message ,
Generic Types are not allowed in RFC.
How can i handel this.
Regards,
Susheel Joshi

Hi Susheel,
RFC module interface parameters (import, export , tables) can only refer to data dictionary types. Hence if you currently have one of the parameters referring to a type defined in your function group main include or in a type pool, you need to create a SE11 data dictionary structure/ table type for that and then change the data type reference.

Error BT616 when calling function module SXPG_COMMAND_EXECUTE in background

Hi All,
We use function module SXPG_COMMAND_EXECUTE with a custom command we defined in SM69 to move files in unix (mv command).
The function module call has worked fine for almost a year and recently we have been seeing an error (BT616) in our job lob (SM37) when the program is run in background. We have not been able to reproduce the error in foreground mode and it seems to be occuring only periodically in the background. (The appropriate SAP authorization objects where assigned to the batch job ID and the steps on the batch job.) We are in the process of setting up the trace flag and performing analysis on the trace log via ST11 to help identify the issue.
After perform analysis on SXPG_COMMAND_EXECUTE, the error is occurring when calling function module SAPXPG_END_XPG for exception 2, system failure, yet function module SAPXPG_END_XPG does not exist. I assume this is a program at the operating system level and is just a signature of the parameters to be passed to the operating system program.
Below is part of the SAP function module SXPG_COMMAND_EXECUTE that is failing.
* Now we have to wait for the termination of the external
* command if the caller wants us to.
    IF TERMINATIONWAIT = 'X'.
      CALL FUNCTION 'SAPXPG_END_XPG'
        DESTINATION DESTINATION
        IMPORTING   EXITSTAT = STATUS
                    EXITCODE = EXITCODE
        TABLES      LOG      = LOG
        EXCEPTIONS COMMUNICATION_FAILURE = 1 MESSAGE MSG
                    SYSTEM_FAILURE        = 2 MESSAGE MSG.
I performed a where used on function module SXPG_COMMAND_EXECUTE, and most of SAP programs call the function module with the parameter TERMINATIONWAIT = 'X', so I assume we should pass X as well.
Any ideas on what could be causing this issue?
Mike Vondran

I also remember I have this kind of issue, as I have some UNIX script at OS( UNIX) level . The problem was with the ID , as it dont have proper authorization at OS level ( UNIX ) . Please check this ID authorization. This could be the one of reasons if youre sure from SAP standpoint.
Hope thisll give you some guide line..
Thanks

Unable to send table to function module using RFC

Hi all,
I'm trying to send a table from XI to a function module using RFC. I tested the process first using indivdual parameters. At this point there were no problems. Now I changed the import parameter of
the FM into a table and imported the changes into XI. I changed the Message mapping and tested it with multiple records. When I run the process XI calls the FM but the FM doesn't receive any data. I tested this by puting a break-point in the FM. There are no errors in the XML Messages Monitor. I found this message in the Communication Channel Monitoring:
Short Log:
Server 0 10_39293 Receiver channel 'CC_BackendIn' for party '', service 'BS_Backend' (internal name 'RfcClient[CC_BackendIn]')

Any ideas?
Thanks for your help!
Regards,
Ivo van Ee

Hi everyone,
thanks for your prompt response! I tested the mapping in XI and didn't find any error here. So I concentrated on the receiver side. There were some communication channels running on the server that were generating errors. I stopped alle the communication channels and started just the two communication channels for this process. This time the table was successfully exported to the function module! Problem solved. Still not sure what caused the problem in the first place, but everything is working fine now.
Thanks for your help.

Ivo

Function module VS RFC

any body can help me to know the difference between function module and remote function module...?

hi,
function module: is a function module it is available with in sap system only.
RFC
A remote function call is a procedure for data interchange between a client and server. Typically the client calls a server program and the server returns the results via a TCP/IP connection. Remote function calls may be associated with SAP software and ABAP programming and provide a way for an external program (written in languages such as PHP, ASP Java, or C, C++) to use data returned from the server. Data transactions are not limited to getting data from the server, but can insert data into server records as well.
A remote function call (RFC) is the call of a function module that runs in an external system to the calling program. Although it is possible to call a function module in the same system as an RFC, normally RFCs are used when the caller and the called function module run in different systems.
In the SAP system, these functions are provided by the RFC interface system. The RFC interface system enables function calls between two SAP systems, or between a SAP system and an external system.

Asynchronous function module - why RFC ?

Hi,
I am using CALL FUNCTION ... STARTING NEW TASK ... DESTINATION 'NONE' to start an asynchronous process.
For this to work, the called function module must be unfortunately RFC enabled.
Actually I do not want that anybody external can call this. Can I find out, if I was called from "outside"? Otherwise I create a potential security hole?
Regards,
Bruno

A sound security concept is the cure for many problems.
In this special case it is much easier said than done... ;-(
STARTING NEW TASK automatically uses DESTINATION 'NONE' even if you do not code the destination extention, therefore the FM must be RFC-enabled.
FM RFC_WITHIN_SAME_SYSTEM checks that the caller is within the same SID, which is what the internal destination NONE is.
To use security for this you must consider that internal destinations do not check object S_RFC by default. But real external callers will encounter the check. This means that to use authorizations based security you must have all your users (everything from end users to the RFC connections users into this system) as having explicit and restircted RFC authorizations which also do not include the function group which this FM belongs to.
Additionally the field is 40 char long (as are the object names) but the authority-check statement truncates the function group name at the 15th character as it can only deal with 16 char.
An finally, anyone who does not know the object is very likely to pop a * value into it when it turns up, and it will ...
In this case I also think that FM RFC_WITHIN_SAME_SYSTEM is the more reliable solution. After all, SAP also use it for exactly this purpose.

Julius

BTE Name in Called Function Module

Hello,
A function module say XYZ is called from a BTE. Can I know the name of the BTE which called the function module XYZ inside the function module XYZ ?
With Regards,
Avisesh.

I think this document may help you...
<b>Business Transaction Events</b>
This activity describes how you can connect additional components (such as in the form of function modules developed yourself or a product from an external software provider) to the standard R/3 System.
There are two types of interface available in the General Ledger
Accounting (FI-GL), Accounts Receivable and Accounts Payable
(FI-AR/FI-AP), and Sales and Distribution (SD) components for this:
1. Publish & Subscribe interfaces (also called "informing interfaces" in the following) These should inform you about particular events (such as a document being entered) in the SAP standard application and make the data generated as a result available to the external software. The external software does not return any data to the standard R/3 System.
(I'm confused. MIT is using two business transaction events for the SD to FI interface. Both of these events are Publish & Subscribe interfaces. They both return data to the SAP standard application! They both change the FI document before it is posted. What I've figured out is that if there is an export to memory and an import from memory before and after the function call, then we can't modify the data. We can check this in the calling function module - OUTBOUND_CALL_00503110_E or OPEN_FI_PERFORM_00001020_E, etc)
Examples of such events in the R/3 System are:
Master record was created, changed, or blocked
Document was entered, parked, changed, or reversed
Items were cleared or reset
Additional processing can be caused in the additional component on the basis of these events and data:
Starting a workflow
Generating or changing additional data
Requesting correspondence
FI Clearing (F-32) calls (gathered via SE30):
Function OPEN_FI_PERFORM_00001020_E (can't modify data)
00001020 POST DOCUMENT: Prior to final checks
EVENT
This Event is reached prior to completing the document. The checks that are carried out at this point include checking, prior to posting, that the document balances to zero, and calculations for tax offsetting. This Event is accessed once per standard posting process and is similar to validation at document level (Event 0003). A document number has not yet
been assigned when this Event is reached.
INTERFACE
All document line items created and the document header data are
transferred (both as tables).
Parameter
T_BSEG
T_BKPF
Function OPEN_FI_PERFORM_00001025_E (can't modify data)
00001025 POST DOCUMENT: Final checks completed
EVENT
This Event lies following all checks on the whole document, but prior to number assignment. Following this Event, no further error messages may be sent. The document is complete at this point, and no further changes can be made to it prior to posting.
INTERFACE
All current data, all document data relevant for the posting, and various control parameters are transferred to the additional component. At this point you can still implement your own checks on the current document data.
Parameter
I_BKDF
T_AUSZ1
T_AUSZ2
T_AUSZ3
T_BKP1
T_BKPF
T_BSEC
T_BSED
T_BSEG
T_BSET
T_BSEU
Function OPEN_FI_PERFORM_00001030_E (can't modify data)
Function OPEN_FI_PERFORM_00001140_E (can't modify data)
2. Process interfaces (also referred to as "process" in the following) Process interfaces are used to submit business processes to a different control which cannot be realized with the standard system, that is process interfaces replace standard processes. Here you can structure determination of individual field contents or of specific reactions to process flows individually. It is possible to connect different external developments to the standard R/3 System. The additional developments are generally carried out using the ABAP/4 Development Workbench. This way you can, for example, influence the control of payment transactions. Selection of payment method, house bank and partner bank can be made using the payment data (currency, amount, and payee) according to a selection logic which you have defined.
FI Clearing (F-32) calls:
Function OPEN_FI_PERFORM_00001120_P
Function OPEN_FI_PERFORM_00001130_P
Function OPEN_FI_PERFORM_00001150_P
Function OPEN_FI_PERFORM_00001170_P
Standard Settings
Sample modules are delivered in the standard R/3 System which you can
copy into your name range and fill them with statements there.
Activities
1. Enter a product using "Settings -> Customer's products". Actually, in 4.6C, from transaction FIBF (IMG -> Financial Accounting -> Financial Accounting Global
Settings -> Business Transaction Events):
Settings -> Products -> ...of a customer
There are generally a large number of function modules belonging to a product which can be called by different program events from within the standard R/3 System. A product can also be an external software component. If the product is in an external system, enter an RFC destination here. If the product is in the same system, you do not have to enter anything. Important: Do not forget to activate the product after making the following settings.
2. Establish the interfaces with which the R/3 System provides you. To do this, choose
Environment -> Info system (P/S)
or
Environment -> Info system (Processes).
Execute the program. You should enter "A" as the
attribute type. You see the respective interfaces with which the R/3 System provides you. Note the key of the interface which you require.
You can also select:
By particular SAP application components
By particular events by entering intervals
Which interfaces are used in activated products
Which interfaces are used within a particular country version or within a particular industry
Which interfaces are used within a particular customer product
3. Enter the function module which you have developed yourself. To do this, choose either Goto -> Edit modules within the info system or Settings -> P/S modules or Process modules -> Customer's in the "SAP Business Framework" menu. Make the following entries:
Key for the interface
The product that you want to use
Function module which belongs to this product.
You can also enter several function modules for a product. Caution:
The function module must be within your name range, that is must begin with the letter Z. You leave the Ctr and Appl. fields blank unless you want a particular country version or a particular SAP industry-specific component to be enhanced or replaced instead of the standard process flow.
4. Fill the source text of your function module
and activate it. To do this, go again via Environment -> Info system (P/S) or Environment -> Info system (Processes) into the information system and execute the program. Then proceed as follows:
Click twice on the interface you have chosen. If you want, you can look at the interface at this point by choosing Goto -> Interface. Then choose the Back function again afterwards.
Place the cursor on the relevant line and choose Goto -> Function library. You see the sample function module delivered by SAP.
Copy the sample module delivered by SAP and call it the same as the function module entered in step 3.
Fill the source text of the empty function module.
Activate the function module.
Activate the product as described in step 1.
5. Run the R/3 program affected and test whether calling your function module works.
Further Notes
The other menu paths are only used for information about additional components delivered by SAP or about software already installed by external software providers.

Problem with Function module PTRA_WEB_ADVANCES_SAVE

Hi Friends,
We are posting advaces to this function module: PTRA_WEB_ADVANCES_SAVE thru ASP.Net developed application.
while calling this function module thru RFC saying error is ' RFC called failed. RFC error status19 '.
what might me the reason for this error. I am getting this error for this Function module only. i tried with other function module, then it is working fine. but i want to use function module to post advances..
Any suggestions please.
Thanks,
Naveen

Must be an error in data submitted to the FM via the RFC...the FM is remote enabled, so check your data values AND FORMATS very carefully... are you getting the return table back? If so, what's in it?

Uncatchable exception: BSP calling Function Module

Hi all,
currently i'm facing a very weird problem. My application class calls function module
HR_INFOTYPE_OPERATION. Normally, in case of an error, the function module gives you back a return parameter. But if i call it from my BSP, the processing doesn't leave the function module. It directly throws an exception ERROR_MESSAGE_STATE instead of writing the message into parameter return.
If i call the function module with the same parameters from a report, it works fine and the error message is written to return parameter without throwing an exception.
What am i doing wrong? I don't want that exception and need to go on with filled parameter result.
Regards
Mark-André

Hi MA,
try using ERROR_MESSAGE in the exceptions list, like this.
CALL FUNCTION 'func_name'
     EXPORTING
          string            = text
          pos               = position
     IMPORTING
          string1           = text1
          string2           = text2
     EXCEPTIONS
          string1_too_small = 1
          string2_too_small = 2
          ERROR_MESSAGE     = 3
          OTHERS            = 4.

Can we call Function Module from Process Chain?

Hello experts,
I have a small question.
Can we call Function Module(SE37) from Process Chain?
If yes can you please provide some example link?
I m new to BI world.
regards

Hi,
Create one ABAP program and call the function module from that program. Check the link to know how to call a function module from an ABAP program.
http://help.sap.com/saphelp_wp/helpdata/en/d1/801edb454211d189710000e8322d00/content.htm
http://help.sap.com/saphelp_wp/helpdata/en/9f/db98ef35c111d1829f0000e829fbfe/content.htm
Then use process type "ABAP Program" in your process chain and add the program you have created. So then this program will be executed via process chain and this program will call the function module.
