AR Invoice Dispute amount Update

In an AR Invoice we can update the Dispute Amount Information from a number of places :

1. More TAB on the AR Invoice Screen
2. Action --> Installments  from here we can update the Dispute amount and Dispute date details
3. Account Details Screen

From either of the 3 places when Dispute information is updated the information is reflected in the table ar_payment_schedules_all

However when the information is updated from the MORE TAB on the AR Invoice Screen in such a case the timestamp information od ar_payment_schedules_all is NOT Updated . 

In scenarios where we have a data warehouse which is based on the Timestamp update of WHO columns in such scenarios we need to ensure that Option 1 is not followed for updates and business follows Option 2/3.

Prevent Option 1 by using personalization or changes to Custom..pll
