What causes this issue?

An error occurred while accessing the table RZLLITAB.

System Response

The system attempts to store the group of the application servers that
you chose for parallel generation, in table RZLLITAB. The reason for
why the access failed may be, for example, that access to this table is
currently blocked by another user.

How to fix this error?

Call transaction RZ12 (CCMS: RFC Server Group Maintenance) to check the
definition of the group. If access to table RZLLITAB is being blocked
by another user, you are told this directly after calling the
transaction.
