Hi,

Could you please execute this URL http://<host Name>:<port>/rep/hmidiag/ext?method=info

with right parameters to check integration repository is running or not?

and also check whether you imported Basis software component in to Integration repository?

Thanks,

Jag

Hi,

make sure you have the roles - SAP_XI_CONFIGURATOR_J2EE and SAP_XI_DEVELOPER_J2EE against your user id to access ES Workplace....

Thanks

Thanks for the reply. Is that something we can request and ES Workplace admin would do it per individual basis ?
