How to: Modify Attribute Values Using the Last Contributing Management Agent
The following examples show how to set the value for an attribute that is configured for manual precedence only if a specified management agent changes the value. The first time the attribute is set, the example sets the attribute. From then on, only the management agent that first set the attribute can change the attribute. Other management agents cannot change the attribute value.

Const CSAttributeName = "displayName"
If mventry(MVAttributeName).IsPresent Then
' Only allow the original management agent to modify the attribute.
If mventry(MVAttributeName).LastContributingMA.Equals(csentry.MA) Then
mventry(MVAttributeName).Value = csentry(CSAttributeName).Value
Else
Throw New DeclineMappingException
End If
Else
' This is the first time the attribute is being set.
mventry(MVAttributeName).Value = csentry(CSAttributeName).Value
End If
