The change of the component/view for a FS BP after upgrading
Prior to CRM 7.0 EHP3, when creating a FS BP, the system takes the view to BPFS_HEAD/BPHeadOverview.
But after update to EHP3, the system was navigating to view BP_HEAD/BPHeadOverview.
The overview page for the FS Business Partner technically would then be BP_HEAD/BPHeadOverview as opposed to BPFS_HEAD/BPHeadOverview.
This is to take full advantage of any standard Business Partner functionality.
How to change it back to component BPFS_HEAD:
If you would like to use the previous component BPFS_HEAD as the lower release, you can switch off the business function CRM_FS_BPHEAD_UI via Tcode SFW5.
