In order to analyze the underlying schedule data, SmartPM™ treats schedule constraints as follows:

• Finish On or After - Milestone only imported and converted to a start constraint
• Finish on or Before - Always ignored
• Mandatory Start - Always included / imported
• Mandatory Finish - Milestone only imported but converted to a start constraint
• Start On - Always included / imported
• Start On or After - Always included / imported
• Start On or Before - Always ignored
• External Dates – Converted to a Start Constraint
