Platform parameter for method OpenWorklistItem

Hi,

I have a short question for the OpenWorklistItem Method of the K2 Runtime API.

Does  the parameter Platform has any effect or is it just an info? Is it important to set this parameter by using in a ASP.NET application for example? What happens if set or not set?

public WorklistItem OpenWorklistItem(  string SerialNumber,  string Platform,  bool Alloc,  bool IgnoreStatus)
