Need retrieve data of completed process

Hi,

I use K2 ROM for retrieve data of a process instace with the Connection.OpenWorklistItem(serial,"ASP") method. The problem is when the process is completed In thos case the method doesn't find the process intance because the instace don´t exists in the K2 database.

Can I retrieve the data of a proccess completed with any method, similar OpenWorklistItem method?

I have prepared all my code to use WorklistItem class to run my application.

Thanks for all,

Álvaro.
