Hi Experts,

Our client had their patching 19D update over the weekend and they noticed something different with outstanding subledger transactions.  We checked this update and this was from 19C.  They would like to disable this and unfortunately having difficulty in locating this Opt-In feature.  Also, we noticed in the document for Performance Enhancements in Period Close Work Area (https://www.oracle.com/webfolder/technetwork/tutorials/tutorial/cloud/r13/wn/fin/releases/19C/19C-financials-wn.htm) that it's no longer optional from update 19D.  Does this mean whether they like it or not they have to use this feature?
