Does HRESS_C_PERSINFO_CONFIG support UP (public sector)

Background

We have implemented the public sector components.  Every pernr in pa0003 has a VIEKN value of 'UP'.

Current

We have copied HRESS_CC_PER_CONFIG to a Z object.

For CONFIG_10_IT0006 we have configured the HRESS_CC_PER_DTL_ADDRESS_XX to be replace with ZHRESS_CC_PER_DTL_ADDRESS_US which has some extra fields.

However, because VIEKN = 'UP', the configuration is not being replaced.

If I change VIEKN = '10', then it does get replaced.

Is UP meant to be supported as delivered?

At this point we have no one in our system with a value other than 'UP', is it just easier to replace the XX configurations directly with US configurations and take the app cc out of the equation?
