QC Workflow - Copy field from test in test plan to field from test instance in test lab

Hi all,

When I want to add a test to a test set in Test Lab, a custom field from this test should also be copied to the custom field in the test instance of the test set.

I found already some information in following post, but this is not working at all:

I also tried something else, but

'Variable
Public ActiveTestInstance, valueToCopy


In Test Plan:
Sub Test_MoveTo
  On Error Resume Next
  If ActiveModule = "Test Lab" Then 'I was hoping that navigating the test tree in test lab would trigger the MoveTo function from test plan.
  valueToCopy = Test_Fields("TS_USER_01").Value
       End If
  On Error GoTo 0
End Sub

'In Test Lab
Sub TestSetTests_AfterPost
  On Error Resume Next
  
  TestSetTest_Fields("TC_USER_01").Value = valueToCopy 
  
On Error GoTo 0
End Sub

the subroutine Test_MoveTo is not being triggered from within Test Lab.

Anyone have any idea how to pass on a field when adding a test to a test set?

This would be a great help. Thanks!
