Hello,
ClearCase is not supported by LabVIEW, if you want to use a SCC, you can perform this task with the following SCC providers: Perforce and Visual Source Safe and Built-in.
Built-in SCC is recommended only for small projects and is available in LabVIEW at no additional cost. “Microsoft Visual Source Safe” and “Perforce SCM” are complete SCC tools that are fully integrated into LabVIEW but must be purchased from the corresponding vendor.
You can find more information at the following link:

If you really want interfacing LabVIEW and ClearCase, VI Engineering can perhaps help you:
