Call a RFC function in VB but without SAPGui install in the system.

Hi,
Do you have example of code, to be able to call a RFC with the VB or C/C++ without needed to have the SAPGui install in the client.
The RFC will be call by a server, so I don't want to install a SAPGui release on this server.
Regards
Frédéric

Hi,
You can access the RFC using VB by the SAP DCOM connector, or for a more basic solution you can access the wdtfuncs.ocx(ActiveX control).
I think it has a Login control in it, you can have documentation while installing RFC SDK from SAPGui CD and it will give you some basic samples of how to use these controls.
Or you can search in help.sap.com and search for "Example Application with the Function Control" and it should return the results to give your VB example.

Problem while calling an RFC Function Module in Background

Hello,
I have created a RFC function module for reading data from an external DB system. The FM calls an external RFC program (coded in C++ using RFC SDK), which delivers the required data. This external program is maintainged as an TCP RFC Connection in SM59.
Further I have created a report, that calls the RFC function module to get the data from the external RFC programm.
My problem is, when I call the report in foreground, everything works OK, the RFC connection works and data can be read from the external program.
However, when I schedule the report to run in background as a job, the report is stating in the protocoll that there was a problem calling the defined RFC connection (although the connection is working properly at that time).
More funny is, this particular problem with running in background occurs only in the productive system, in test and development system the report works correctly also while running as a job in background.
Can you suggest the solution to this problem? Could it be something with authorisations or server settings?
I will be on holiday for the next 6 weeks, so take your time to answer .
Regards,
Dusan.

Please read the forum rules about u r g e n t ...

This is an external RFC server program, not a remote enabled ABAP RFC function module as the others seem to be assuming, right?
Is it possible that your DEV and QAS systems only have one application server, but the PROD has many and dedicated one(s) for processing low priority background jobs?
It might be that the target server of your TCP connection is not this BTC instance, and your RFC server is returning the data "locally" - so, into nirvana...
Just guessing, but might be worth checking.

Calling a RFC function in non-SAP application

Hi,
I can call a RFC function in a .NET application. Here there is no problem.
But if an ABAP program submitted in this RFC then I can not call this RFC?
Can I call an RFC ( it submits another abap program) non-SAP application.
Thanks.

Hi Astron,
Could you please close the thread as answered.

Calling Synchronous RFC Function Module in Background

Hi all,
Currently we are working on some requirement where in we have to retrieve data from one system(CRM) and update the same into another system(ECC). We have developed a RFC Function in CRM system and it is being called from ECC system as in synchronous mode via a batch program.
Now since all sychronous call to a RFC function will be dialog there is a constraint on the runtime which is being set by maximum run time for each dialog work process. So my question is there an option to call an RFC function synchronously in background (background task) so there is no runtime performance.
The standard TRFC, QRFC calls in background runs asynchronously and so I am trying to check with the SDN world as whether has anyone tried SRFC(Synchronous) call in background?
Thanks in advance,
Jagath

So my question is there an option to call an RFC function synchronously in background (background task) so there is no runtime performance.
One solution would be to increase the value of the "time out" parameter defined the CRM system. This i feel is not a fool-proof solution as the run-times cannot be predicted. Check this thread: Re: RFC timeout profile parameter
For me a better solution would be to implement tRFC call instead of a synchronous call. Any reasons why you don't want to implement a tRFC ?

Calling a RFC Function Module

Hello Guys,
I have a question regarding calling a RFC function module.
In BW - BI 7.0 I call a RFC function module:
(The ABAP program in BW-BI 7.0 is below)
CALL FUNCTION ''ZTESTFUNCTIONMODULE' " Function module in ECC
     DESTINATION 'DECCLNT110' " ECC system
    TABLES
      it_gl_item   = it_gl
      it_errlog_gl = it_errlog_gl.
The 'ZTESTFUNCTIONMODULE'   is RFC enabled in the ECC system.
The purpose is we retarct the data from BW to ECC.
When I run the function module it always asks for the user id and password.
The SAP logon screen appears and it asks for the user id and password.
The destination is maintained in the SM59 transaction and also the user is maintained there. I think it should login automatically into remote system and return the tables. is it correct. How to skip the logon screen.
Do I have to pass the user id and password in the function module. I think it should take the user id from the SM59 destination. Is it correct.
Please advise. As always thanks for your help guys.

Hi Senthil,
I think you answered your query in your question itself
The user ID and password need to be maintained in RFC destination in SM59.
Go to SM59 and then click on test connection..if it does not ask for ID and passwoed that means correct ID and password is maintained in SM59 otherwise maintain it.

Hey shahbazfromgbr,
Thanks for the question, and welcome to Apple Support Communities.
I understand you are having issues with sound output on your iPhone 4S. For troubleshooting steps, the following article provides the best information:
iPhone: Can't hear through the receiver or speakers
http://support.apple.com/kb/TS1630
1. Verify that there is nothing plugged in to the headset jack, including headsets, headphones, or adapters.
2. Make sure the Ring/Silent switch is not switched to silent.
3. While on the Home screen, adjust the volume buttons. If you see the icon below, indicating that headphones are attached, there may be debris or an object lodged in the headset jack:
4. Check the headset jack. If there is an object lodged in the headset jack that is not easily removed, have the iPhone serviced to remove object.
5. For Original iPhone: If there is light debris, such as lint, in the headset jack, try connecting a pair of headphones to the headset jack and then remove the headphones. Repeat this several times to remove the debris.
6. If you have installed a protective film on the display, either ensure that the receiver is not covered or remove the film completely.
7. Check the receiver mesh (which is on the top front of the device, above the display). If it appears blocked, use a clean, small, dry, soft-bristled brush to carefully and gently brush away any debris.
8. If you have paired with a Bluetooth headset that is nearby, either use the headset or turn Bluetooth off (choose Settings > General > Bluetooth).
9. Restart the iPhone.
10. If restarting the iPhone doesn't resolve the issue, try restoring the device.
11. If the issue persists, go to the Service Answer Center - iPhone for information on service.
Thanks,
Matt M.

Plug the device into the computer.

My iPhone 5, periodically,will not show the call waiting number. It beeps but will not give me the option to swicth over or show me who is calling. The call doesn't appear in my "recents" either.

Do a GI but no serial number in the system

Dear Gurus,
I have one scenario,lets say we have a data for the month of october 2009 and november 2009 ,the data means the serial number of material.the data before october 2009 already uploaded by consultant but for the rest they not upload it,maybe they dont have the data i think.Then,we need to do the GI base on the DO we get for the month of october and november 2009,but no serial number in the system.What step i should follow to do the GI.
First,if i create the serial number,thats no history like PR,PO,GR and no stock will added in mmbe.that why cannot do the GI because no stock will added.
Sir,can u tell me what is the best way to do this GI..
Thanks
/Shah

Hi,
You can not do GI if the serialisation procedure is maintaiend for delivery / issue. In this case, you need to upload serial number with the help of IQ01 / 08.
If the delivery does not ask for serial number, then you can directly issue the material without serial number.

HT5621 I have changed my AppleID but I can't get the "system preferrences" to show my new AppleID. What am I doing wrong?

I have changed my AppleID but I can't get the "system preferrences" to show my new AppleID. What am I doing wrong? I am running 10.9.2. I support multiple devices on this icloud account and they all work fine. Its just the mac mini ...

I found a post with the answer. Basically I just logged out of the iCloud. My concern was that I would loose my contacts. But when i logged back in with the correct AppleID -- it was all there.
Thanks!

Which versions of InDesign are you referring to? What are the operating system specs for the machine?
