HS&E: modifying values of the out of the box delivered at codes

Hi All,

Is it OK to change the UDC values under HS&E modules or delete some values that client won't require - from the perspective of a new JDE implementation.

An example could be UDC 54HS/SV - Incident Severity.

If client wants to define all values in this UDC, would it be OK to do that and then add what client requires. Would it impact out of the box OVRs in some way?

Also, if client wants some reporting (say OVR) which is not available out of the box in JDE, and we do decide to create new E1 OVR reports, shall we use Cat Codes or UDCs? How does the decision impacts OVR?
