Can’t convert requirements using special charactes to tests

Currently the conversion requirements to tests is denied in case there are special characters within the requirement name.

As result the conversion of a great number of requirements to tests isn’t possible.

For that I written a following  workflow code in Test_New, but still its not working. Can sombody provide some suggestioin

Sub Test_New
On Error Resume Next
Dim TestName

Set reqFactory = td.ReqFactory
Set req = reqFactory.Item(Req_Fields("RQ_REQ_ID").value)
TestName = req.Name
TestName = replace(TestName, ":", " ")
Test_Fields("TS_NAME").value = TestName

On Error GoTo 0
End Sub
