Problem with deploying SAP Business One DEMO Database in HANA Studio

Hi colleagues! Sorry to ask this silly question but we have a problem deploying a demo database for SAP B1 in HANA Studio.

We were able to add the UK database following step by step the SAP NOTE 3011710 but we are not able to login.

We get the following error message:

We have also found this post regarding this error here but is not solved:

We have two users the SYSTEM user and the B1ADMIN (created by us following the Administrator guide granting the required permissions)

Is there any chance that someone can explain to us how we can do it properly?

Thanks in advance for al your help!
