Hi Chris,
For infotype 105, we have communications view in personal profile.
We can enable and show the required subtype of 105.
I didnot understand the relation between 0006 and 0105, you want to update the emegency address and it should internally update IT0105's respective subtype.
For displaying only phone number, we can have subtype specific screen, its though Zconfig as pointed out by Imran. Its simple and straight forward.
The main challenge here is in splitting Address into two views in personal profile, SAP standard address will show all the subtypes in one place.
May be from the feeder class or any other location we can try to restrict the emergency address showing up.
For ur 2nd view showing only emergency address. Creating a custom view with respective custom feeder class would be simple solution. I personal prefer showing communications view instead of custom one.
Let us know if you are looking for some thing else. We can implement same in different ways.
Regards,
Yugandhar
