SAP DataSphere

1. Click Add Subaccount button in SAP Cloud Connector.
2. Input all the information of the Subaccount in SAP Datasphere.
3. Click Save button.

The input user name or password is incorrect. 

Make sure that the e-mail address is associated with an active S-User ID. To avoid login issues, the e-mail must be associated to 1 S-user ID only. To validate the password try to login to https://accounts.sap.com with the same credentials entered in the Cloud Connector. If the login fails, use the "Forgot Password" link in the logon page to reset the password.

• • The password from the SAP Universal ID is managed in a different URL (https://account.sap.com for SAP Universal ID) than the one mentioned above and this SAP Universal ID password does not work.
  • You must use the same password you use to access https://accounts.sap.com (in other words, the password of the specific S-User ID related to the email address).
    
    Note: Users created in the Technical Users application cannot be used in the Cloud Connector. Reason being these users are not stored in the SAP ID Service. They are only used in SAP Solution Manager's Support Hub Connectivity.
    In addition, it is not possible to use SAP Universal ID in the Cloud Connector yet. Log on with the password associated with your S-user account.
