The above cumulative patch not only has few critical bug fixes, it also has few product enhancements being included in it. The major enhancements that are released as a part of this cumulative patch is
Consideration of “Options End Date” into Amortization– Functionality has be provided for users for considering Option end date for Amortization. This flexibility is provided via a profile option and while performing Renewal and Termination Options users can choose the amortization end date in a Lease to be that of Option end date or Lease End Date.
Liability Flag Change – Discontinued to send the Liability Flag of Yes/No on Invoice Line DFF flag which was sent to AP in Invoice Line DFF number 2. We are now using Reference Key1 field is reserved for Property manager to store or derive PN Lease Liability Flag
Decoupling feature – In the Link term feature the Amendment Commencement date and Contraction Date are coupled, and they cannot be separated.
 A new flag to be introduced and this will be called as ‘Expired Terms’ with values of ‘Y/N’. Users can decide to have Contraction adjustment to be spread until Lease End Date or Term End Date. 
 Remeasurement value will be calculated only at the Lease level unlike linking of terms where it is captured at term level 
Add terms from past date – Add term calculations are going to be as of ACD and hence no reserve gets created if start date for ROU/Liability.
