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..
