Revenue & Interunit Billing Expense Chartfields - after PUM29 - Bug 27845780

Hi,

After applying PUM29, we are encountering an issue with Inter-Unit Billing and receiving a message from support that this is "working as designed".    Would appreciate input from others if this is also an issue for them  (Grants, Contracts, Projects, AR & Billing...++).   We are experiencing two issues:

Issue #1:    When entering an invoice online and specifying the Revenue Distribution, after applying Bug 27845780, the PCBU and Activity ID are greyed out on the Revenue Distribution.   We understand that Project Information should be specified instead on the Line-Project information.   However, we are still able to enter against "Project ID".   We feel that this should be fully greyed out in the event Project Costing is installed, to prevent any possible confusion.   Simply, project information should not be specified on the Revenue Distribution, but instead should be specified on the Line-Project Tab.   (see screenshot below, even though it's for the Inter-Unit Expense side, the Revenue Distribution appears the same way)
