Authentication incorrect to connect to SAP system via business application studio

[vvinod]

Hello, I am trying to connect to backend SAP system via business application studio(BAS) to build fiori apps. However, when I select the data source as SAP system and enter my SAP GUI credentials for service username and password, it says authentication incorrect! as shown in the picture.

The destination is configured in cloud connector to connect to on premise SAP system and the SAP system shows up in BAS.

What could be wrong here?

Thanks Vinod

Hi,

I have the same error, I think it is a platform error, because the credentials are correct, and when I try many times, in the abap system the user is blocked, but I am sure that my password is correct.

Who can help us?

Regards,

Johnny

Hi vvinod ,

The "HTML5.Timeout" property is defined in milliseconds. You should probably change its value to 60000.

BTW - In many cases there's no need to add this additional property to the destination configuration.

Hello Raz Korn,

I changed the value of timeout property but it has no effect on the error that I am receiving for Authentication failure.

What values are expected for service user name and password? Are they not same as user id and password that we use to logon to SAP system?

Thanks

Vinod

When configuring the destination to use basic authentication the credentials (user/pass) should be those for accessing the SAP system. If configured correctly then during the app creation wizard, in the Data Source selection step, you will not need to provide credentials. It might be that the user you're using is locked. If you change its password, do not forget to update the new password in the destination configuration.

As gregorw mentioned above you can configure the destination to use NoAuthentication and then whenever accessing the SAP system one will need to provide the credentials.
