The time dimension contains multiple entries for which the time
reference characteristic (NCUMTIM) is set to 'unlimited'.

How to fix this error?

Contact your system administrator.

Procedure for System Administrators

To allow compression to be carried out, the entries must first be
removed from the InfoCube.
To do this, you can proceed as follows:
Delete all packages that contain records in which the time reference
characteristic has the value 'unlimited'. You can identify these
packages by using transaction LISTCUBE.
Reload these packages and create a rule in the transformation that maps
the value 'unlimited' to a year before 9000.
Using transaction RSRV, then delete all entries that are no longer used
from the time dimension.
The InfoCube can be compressed again.
