Property Bag for Session

This Property Bag provides additional information to the BeginNamedTransaction function of the ISCSession interface and can be submitted as the second optional argument of the function. The contents of the bag can have one of two available forms: native format or as a string. The client can populate the bag in either of these two forms. Different forms can be mixed in the same instance of the bag.

Not all properties have to be present in the bag when it is submitted. All property data as well as property names are validated by the API, and all are either accepted or rejected. The rejection forces a method call to fail.

The transaction properties are in effect at the initiation of an outer transaction and are confined to the scope of the transaction.

The following table lists the Property Bag properties and datatypes for the BeginNamedTransaction:

Property Name	Type	Read-only	Description
History_Tracking	Boolean	No	TRUE � Indicates that all historical information generated during the transaction will be marked as the API event. A TRUE value is assumed if the property is not provided. FALSE � Uses the standard erwin DM mechanism of history tracking.
History_Description	BSTR	No	When the History_Tracking property is TRUE, it provides the content of the history event Description field.
