We'd like to know the feature and limitations of 'Display History' type of actions in Oracle CPQ:

• Is there a way to capture all the transaction history of any Quote in the transaction history xml
• Is there is any limitation on how many previous history can appear in the history xml? Is there a way to increase that ? We have a quote in PROD which was created in 2014 but 'Display History' action shows records from 2018 onwards which is a loss of records of 4 years. However, when history is downloaded I can see the 2014 related records also. I need to know how the complete history can be seen in 'Display History' action output also.
