There exists a feature I had forgotten about....
In XV_UL, the various Unlinked Episode types can be used to map to an owning dept..
The format is XVOP:<company_tla><campus_tla><episode_type>
So a CRIS episode at XYZ for WPP campus would be
XVOP:XYZWPPCRIS, mapped to DIRA12 AND FACILTY CODE 01214, unit DIRA and ward type 12.
These are used to provide DEPT code and facility in T1HKCPP in XV_UL
The data populated using this is HKMPCD HKM2CD and HKNYCD
It may well be not implemented at your sites..
