Hi,

i have a problem with connecting to the SAP R/3 when i want to create a new model with BAPIs.

The error is:

Internal Error has occured.

Plugin name: Web Dynpro Model Editor Services

Method: next Pressed

Message: Internal error - see detail information in exception trace.

Hi Stefan,

Please reinstall the IDE.

First Uninstall the IDE and after that delete the all th plugins in the plugins folder (ProgrmFiles/SAP/JDT/...)

Now install the IDE once .

Hi Stefan,

I don't know, if you solved your problem. Here is a possible solution:

You have to copy the librfc32.dll of the downloaded JCo-Package into your windows/system32 folder.

It may exist there, but simply overwrite it.

Had the same problem (in my case, it was caused by uninstalling Front End 620 and installing Front End 640, probably overwrote the librfc32.dll in the course of that). Getting the newer librfc32.dll from the SP13 CD into system32 directory and rebooting fixed it. Thanks Markus! Much better than 'reinstall NWS'

Hello

I had the same problem and was able to fix with the help of OSS note 832994. It was very tiring to find this message/thread/note; finally it works.

Thank you Sekar.

Hi, thanks for your answer.

I changed the things, but now this problem appears.

org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'
JCO.nativeInit(): Could not initialize dynamic link library librfc. Found version "620.0.941" but required at least version "620.0.1220".)

What can i do with this mistake?
