For Admin user, Start Adaptation button is missing in Fiori / RUI client.
SAP Cloud for Customer
Reproducing the Issue
Logon to C4C fiori client.
Go to any work center.
Click on your profile.
You do not find Start Adaptation option though you have admin role.
If your role is assigned with Partner Development work center, then adaptation functionality will not show up in Fiori.
Go to Administrator.
Click on Business Users.
Search with your user name.
Click on Edit and Access Rights.
Click on Business Role Assignment.
Select assigned business role and then View All.
Go to Work Center and Assignments view and ensure Partner Development is unassigned as below.
You will then be able to see Adaptation option.
