SLD is all fine ,moreover its a local SLD.

ERP 6.0 and EP 7.0 are running on Dual stack.

Datasuppliers are also Okay.The issue is as soon as i click on Create Jco ,an error page (full IE page with error) opens.

Error ,which i have pasted before.

Java is on 7.0 SP 06 . Is this a bug ??

hi,

check the follwing

1) created the technical sytem in SLD and system object in portal for R3 system.

2) SLD port-installation activities should complete

3) check assing SLD related roles and Authorizarion

4) whether you have changed the password for ( administrator / j2ee_admin )

thanks

Please try to restart the Java and check that you are able to create it.I think some service has stopped.

It is not authorization issue because if no authorization then you shall not getthe tab.

you have local Sld for Both the system. i think you should have one local sld and other system should point to that sld.

Thanks

ERP 6.0 and EP are install ,EP is selected as a Usage type.Both are on same host.

Hence SLD is local with both systems there.

Password has been changed ,but i am able to do administration in SLD.

Will try to get some downtime and restart the systems .lets see after that.

Hi Ajay,

Where did you change this password!Was you JCo Destinations working before changing the password!

I had this problem when I tried to change the port number i.e from 50000 to 8000

Thanks

Sunil

[ajjunit84]

I remember ,you were also facing this kind of issue.

Password was changed in clinet XXX and able to login to portal ,VA with J2EE_ADMIn.Also updated the password in Secure Store.

It was never working before.Whenever i click on create Jco it throws a page with the error mentioned.

Anyway will restart the system today .Port..ports were not changed...its ERP + EP ..8002 is being used for BSP/ABAP or SICF etc and 50200 is for portal/Java.

BTW thanks for that ,i did a recheck ..i am able to access services in sicf with port 8002.

Thats all.

Regards

Ajay

[ajjunit84]

I havn't changed the port although.

This is when i am trying to access Jco creation /Webdynpro page a t 5XX00 port.

Hi Ajay,

Please check the RFC Destination-type 'H'.check if this is working (i mean see the user name and password).check the connection,some times this can be a problem.

Thanks

Sunil

[ajjunit84]

I checked ,but there is no RFC type "H" defined in my system.

Can you pls let me know RFC destination name etc..so that i can try.

Also , when trying to save CIM setting its saying "Failed to Set set permissions for Domain"

Found some refrence and reimported the CR content and CIMSAP content ,stopped started SLD ,but sill i am facing this issue.

Regards

Ajay

Refer to docs at []

[ajjunit84]

SLD is configured and running fine.

[Former Member]

Hi,

Please check that we maintain JCO which are of two type.One is metadata and model data.

Do you have your userid in the backend system for which you are creating the JCO.Please check the login mode used in the JCO is Ticket then you shouls have id in the backend System and this system.

Check that the Backend system is defined correctly in the System landscape of this System.

Thanks'

Understand that.But the issue is ,when i am clicking on Create Jco ,at that time its throwing me the exception.

Its not allowing to proceed.

Usually , i use J2EE_ADMIN to create Jco and while providing the connection details ,only then we have to provide the user id present in Backend or SSO in case of Ticket.

Regards

Ajay

Any ideas pls??
