Distinguished Fields vs. Promoted Properties in Biztalk

In Biztalk you can promote a property as either distinguished or promoted properties. Choosing what to use is tricky.

Distinguished fields: In general use Distinguished fields if you want to just use them in Orchestration

• No restriction on field length
• No participation in Routing
• No seperate property Schema
• Not accesible by std pipeline components

Promoted Properties: These are generally used with Routing

• Used in publish and subscribe in the Msgbox
• Field Restictions ( 255)
• Seperate Property schema
• Restricted in the XSD types support compared to distinguished properties

Synopsis: Use Distinguish properties as they are lightweight unless you need them for any special stuff like Routing ,Tracking ,Correlation or custom pipeline behaviour
