Hello Vineetha,
You need to use a system landscape created with the template tye 'TDMS Landscaspe Template'.
Then the same can be assigned to the relevant project created for TDMS for CRM Utilities scenario.
There are no specific roles required for a utilities package, you need to have the same roles as used for other
kind of TDMS copies.
You should first go through the master guide and also make sure that relevant notes are applied as per the below composite note for CRM U :

Thanks,
Rajesh
