Summary:

Implement a change in default date rule field in budgetary control setup post go live

Content (please ensure you mask any confidential information):

we have gone live with oracle financials and procurement cloud application. In the current budgetary control setup Default date rule is setup as "Current Transaction date".

However this is creating fund check failed issue while we are trying to update or cancel the PO created earlier but for which the budget period is closed now. Now, by following note id: Doc ID 2676691.1  Changing the budgetary control setup Default date rule is setup as "Current Transaction date" to "System date" resolves the issue but we observed that while changing the setup in budgetary control page it gives a warning "Changing the budgetary control or encumbrance accounting settings may invalidate the existing data for the ledger ****. Do you want to continue?". We want to make a permanent change in the default date rule to "system date" but kindly suggest if we can do the change in an instance after go live and it will not have any data corruption issue.
