PRJ4: Add Method Returns Wrong Resource Assignment UniqueID

• Microsoft Project for Windows, version 4.0
• Microsoft Project for Windows 95, version 4.1
• Microsoft Project for Macintosh, version 4.0

SYMPTOMS

In Microsoft Project, when you run a macro to return the UniqueID property of a resource assignment (Assignments collection), an incorrect number may be returned.

CAUSE

This problem occurs if you use the Add method to return the unique ID for a resource assignment if the resource has been assigned to the task multiple times. For example, if you run the following macro

   Sub Macro1()
      Dim X as Object
      ' Add resource to task and set variable X equal to first
      ' resource assignment
      Set X = Projects(1).Tasks(1).Assignments.Add(1,1)
      ' Display unique ID for first resource assignment
      MsgBox X.UniqueID
      ' Add resource to task a second time and set
      ' variable X equal to second resource assignment
      Set X = Projects(1).Tasks(1).Assignments.Add(1,1)
      ' Display unique ID for second resource assignment
      MsgBox X.UniqueID
   End Sub

The Add method returns the first assignment for the task when you assign a resource multiple times.

WORKAROUNDS

To work around this problem, use the specific Assignments object to return the UniqueID property as in the following example:

   ' Assignments(2) is the second resource assignment
   ' for the first task
   MsgBox Projects(1).Tasks(1).Assignments(2).UniqueID

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
