BW-Lumira : connection issue - no query is displayed

Hello,

I'm facing to a connection problem between Lumira SP17 and BW 7.01 (SP14): no BW query are displayed when I would like to create a dataset.

As it was indicated into a previous discussion, I've replaced (or deleted) all old copies of my saplogon.ini and SAPLOGON_INI_FILE environment is updated.

But unfortunately, connexion to my SAP BW system does not work. Moreover, if I use a non-existing user in Lumira, there is error message.

I've caught this error message:

No system nodes found on specified system types.No system nodes found on specified system types.

What could actions be performed to solve this issue ?

Thanks a lot for your help.

Regards,

Sebastien
