Hi All,
Iam confused about the concept of Promoted Property and User Defined Property?
The userDefined properties are only be promoted to the flow level?
What is the purpose of Promoted Properties?
If there are any differences Please share us your knowledge.
Thanks in Advance. |

Yes you are.

They can be promoted to any level the documentation says they can be.
| vijsam wrote: |

To alter node properties globally at a flow level.

The key difference is that UDPs can't alter the behaviour of inbuilt nodes.
Thanks in Advance.[/quote]

Hi Thank you Vitor for the response,
Even in UDP we can alter the configuration parameters at deployment time using Configuration manager proxy right?

It would decrease the usefulness of UDP if you couldn't change them at deploy time.

If you mean "do properties promted to flow level show on the Toolkit's UDP tab" then yes. Otherwise no.

You can't (for instance) use a UDP to change the queue a MQInput node reads from.

Using UDP we can change configuration values like Data source names and queue names,but using Promoted properties what are the things we can set?
Ie by which way is Promoted Properties differ from User Defined properties?
Please clarify.... |

No.
That's backwards.
You can change those things using promoted properties.
If those properties are configurable.
You are fundamentally confused by what things have which type of Properties.
Built-in nodes DO NOT HAVE user defined properties. |

No you cannot!
As I indicated above, the promoted properties appear on the UDP tab of the Toolkit view. This does not make them UDPs any more than my Ford being parked in front of a Toyota dealership makes it a Toyota.
Promoted properties are properties of nodes, like data source name & queue name. User defined properties are variables you define for reasons of your own.
I don't see how I can "clarify" further.

Thank you Vitor and Jeff,

| UDP are available only on flow level. Subflows can't access the UDP defined in main flows. If you want the UDP to be accessed in mainflow, create the UDP in subflow and promote it to main flow. In this way, you'll be able to set UDP from main flow and access it in subflow. |

What happens when you try it?
Indeed, what does the documentation say about the scope of a UDP? How does that map the scope of a subflow within a main flow?

Unless of course your Ford had a Toyota engine in it and a Toyota badge on a Ford body, in which case it would have a indentity crisis as it wouldn't know if it was a Toyord or Fota

| Apparently my BMW is made in Oxford, so I think automotive identity crises aren't that far-fetched. |

In which event it would be parked in front of the Ford dealership while I beat the salesman with a trout until he told me what the complementary coffee had been spiked with during the sales process.
