[Former Member]

Hi Can anybody help in this matter very urgently,

I am trying to develope Webdynpro application for accessing R/3 system(was6.2).But in Systel Lanscape directory configuration, I am not able to connect R/3 system.Even in R/3 system also i used transaction RZ70 and test the connection with SLD . i am getting

RFC call failed: program SLD_NUC not registered / CPI-C error CM_ALLOCATE_FAILURE_RETRY.

Some times i am getting this problem:

RFC call failed: partner not reached (host 192.168.212.121, service SAPGW00) / CPI-C error

May be i am getting problem at in providing Gateway Host and Gatewayservices in SLD Administrator and SLD attributes in RZ70 tcode.

Can anybody eloborate the complete SLD Configuration In WAS 6.4(Java) and in R/2(WAS6.2) to provide connection between two to exceute Webdynpro application to access the ABAP functions.

i revised all documentation available on sap help,sdn.Can u give appropriate location where can i find proper information about SLD configuration

Firstly you should have authorization object S_RFC for access RFC.

Then you can create a R/3 connection and test.

After you deploy the application, you will have to define the RFC destinations in the Web Dynpro administartor.

It sounds like a problem that I was running into a few weeks back. I had finished building an Exchange Infrastructure box, and I was getting similar errors. Of course, my problem was that I didn't complete all of the post-installation activities. Particularly connecting the integration server to the system landscape directory. You may want to look into something like this? The solution to my problem was to create an RFC connection on the system, and then enter the information into the J2EE engine via the administration tool. That synched everything together.

Hi Usman,

as Jeff suggested you need to mention the correct Message Server host and port along with a valid logon group information. You mentioned you have given correct msg server info. Will you please check whether the logon group and sap system ids are also correctly mentioned in the SLD creation definition or not?

After you create this SLD you can test its connectivity from the creation screen itself. Once it is successful you need to give more information regarding this SLD in your visual admin.

Hi Usman,

there is documentation on the Service Market Place: go to alias instguides and then netweaver > SAP Web AS ... you will find a post installation guide that speaks of how to configure Data suppliers....this may or may not solve your problem.

Another way to solve your problem is to enter in the ABAP system information manually in the SLD. Just create a now Technical System...Enter the requested mandatory info ( you will need to enter in one valid logon group)...This way you won't need to worry about the data supplier and can get started with the Web Dynpro programming.

Hope this helps!

Hi

Shubhadip's explanation helped me resolve the problem. My JCo destinations test is successful.

Refer:

Shubhadip's explanation:

*************************

"From you rexception it seems in your sld creation you have mentioned the logon group as PUBLIC where actually its not so. To find out the actual log on group, go to your SAPlogon, click on the button Groups, give the system id and message server host name, and say generate list, it will show you the list of groups actually available, you may find something like SPACE, use that for your sld creation."

Thanks

Sriram
