Good Morning Nurul.
As to your first question: "1.Is it possible we create new tenant in USS?"
Yes, you can.
1 Login to the USS-UI and open the 'Request a Service'.
2 From within the 'Categories' section, select 'Service Management Administration'.
3 From the next 'services page', select the appropriate 'Tenant' related service.
As to your 2nd question about 'distinguish between Tenants(is Business Units), please check the following:
The BU-structure for CA Servic Catalog can then be defined like this, through the SC-UI(SC/Administration/Business Units):
'SP Catalog' - Highest-level(Root-BU/Service Provider BU).
'Catalog Sub BU' - The next level BU to hold the catalog/services.
'Users Sub BU' - And another next level, the BU to which the user needs to be defined and login to.
The catalog content/offerings the users would then see, is the content of the 'Catalog Sub BU'.
As in relation to the above, please see the following example:
'CompanyBU' - Highest-level(Root-BU/Service Provider BU).
'Cat1BU ' - The next level BU to hold the catalog/services
AND another/next level BU:
'User1BU' - The BU to which the user needs to be defined to/for.
'Cat2BU ' - The next level BU to hold the catalog/services
AND another/next level BU:
'User2BU' - The BU to which the user needs to be defined to/for.
E.G.
'CompanyBu' has 10 offerings which will show to all the users for all BUs and
'Cat1BU' set with the frist 5 offerings.
User account 'xyz1' is a member of (set to) BU='User1BU'.
And then, whenever the user 'xyz1' logs on to service catalog, that user is able to view the services from 'CompanyBu' and 'Cat1BU'.
Similar:
'Cat2BU' set with the second 5 offerings.
User account 'xyz2' is a member of (set to) BU='User2BU'.
And then, whenever the user 'xyz2' logs on to service catalog, that user is able to view the services from 'CompanyBu' and 'Cat2BU'.
Thanks and kind regards, Louis van Amelsfort.
