What is the usage difference between "Required Properties" and "Required Attributes For Type and State" Operation Behaviour for Save Work item.

Udaya Puthuraya (8811421) | asked Jun 06 '14, 5:03 p.m.
Seems  "Required Properties" and "Required Attributes For Type and State" Operation Behaviour for  Save Work item, look similar.
Is there any difference between them ? 
Is one of exist from legacy version for continuity ?

Any  guidance on which one should be used when both are available ?

Required Properties is the legacy version.

Thanks.   In that case, I assume it is better to use "Required Attributes For Type and State"  when both are available.

Hi Udaya,

Please find the details below, hope it helps.

The new features available in Rational Team Concert version 4.0 allow you to dynamically determine the read-onliness behavior of an attribute. These features are based on new out-of-the-box preconditions called Read-Only Attributes For Type And State and Read-Only Attributes For Condition.

Note about Dynamic Requiredness: Rational Team Concert 4.0 offers the same kind of behavior for dynamic requiredness for work item attributes. In that case the preconditions you may use are the ones called Required Attributes For Type and State and Required Attributes For Condition. The way you would have to configure that preconditions for requiredness is the same you will see in this topic of the article for specifying read-onliness

Thanks Arun.   The text in the article does not mention about "Required Properties" and how it differs from "Required Attributes For Type and State". They looks the same except different names, second one being more clear name.
Seems RTC instances that were upgraded from 3x or older versions to 4x have  both of them, where as new installs of 4x has only "Required Attributes For Type and State" available.
