How can I disable opportunity to revenue line synchronization logic?

By default, opportunity cascading logic keeps opportunity summary and revenue lines in synchronization with each other.

If you no longer want opportunity summary and revenue lines to be synchronized, open the Opportunity Synchronization Cascade Enabled profile option (MOO_ENABLE_INSYNC_CASCADE) and set the value to N. Note that you can enhance and perform opportunity summary and revenue line synchronization for some attributes using Groovy scripting if you choose to disable the predefined opportunity summary and revenue lines synchronization.
