Question:

Received message TSS1630E when attempting to set a UID(0) to user.

Environment:
z/OS
Answer:

To administer UID(0) to users within his or her scope, an administrator who has ACID(MAINTAIN) authority must also have UPDATE access to entity TSSCMD.ADMIN.UID0 in the CASECAUT resource class.

So for this case, the following will need to be done:
  TSS ADD(dept) CASECAUT(TSSCMD) (if not already done)  
  TSS PER(acid) CASECAUT(TSSCMD.ADMIN.UID0) ACC(UPDATE)
