Deprecated 3–way Salesforce, SuiteProjects Pro and NetSuite Integration
SuiteProjects Pro has ended support for the 3-way Salesforce, SuiteProjects Pro and NetSuite integration for customers and projects.
You should use the Projects (Projects) and Customers (Customers) export workflows instead. See Replacing the Deprecated 3-Way Salesforce, SuiteProjects Pro and NetSuite Integration With the Customers (Customers) or Projects (Projects) Export Workflows.
The Enable 3-way Salesforce.com, SuiteProjects Pro and NetSuite integration setting has been moved to the Legacy compatibility section of the NetSuite Connector administration form. You may continue using the 3-way Salesforce, SuiteProjects Pro and NetSuite integration if it is already enabled for your account. However, it can no longer be enabled.
