editing a data field at any point in the process

That depends on a few things, I suppose - mainly, what are you using for your UI and where are you storing this data?

To update a datafield, we need Process ID, if u go for asp.net, then the below code would be useful.

// create a connection string
SourceCode.Hosting.Client.BaseAPI.SCConnectionStringBuilder connBldr =
                    new SourceCode.Hosting.Client.BaseAPI.SCConnectionStringBuilder();

// force the connection string to a specific credential of k2 server admin
SCConnectionStringBuilder cb = new SCConnectionStringBuilder();
cb.Host = "k2server";
cb.Port = 5555;
cb.SecurityLabelName = "K2";
//cb.UserID = "orion";
//cb.WindowsDomain = "";
//cb.Password = "passe";
cb.Integrated = false;
cb.IsPrimaryLogin = true;
// instantiate a connection with this connection string
SourceCode.Workflow.Management.WorkflowManagementServer server = new    SourceCode.Workflow.Management.WorkflowManagementServer(cb.Host, cb.Port);
server.CreateConnection();
server.Connection.Open(cb.ToString());

//Connect to Workflow Server
SourceCode.Workflow.Client.Connection wfConnection = new SourceCode.Workflow.Client.Connection();
cb.Port = 5252;
wfConnection.Open("k2server", cb.ToString());

//Get ProcessInstance
SourceCode.Workflow.Client.ProcessInstance proc = wfConnection.OpenProcessInstance(workflowProcessID);
                              
proc.DataFields["datafieldnametobeupdated"].Value = "Testingg...";
proc.Update();
}
}
}
}
}
// close the connection
server.Connection.Close();
}

If u have Folio with u, u can pass that to k2 database OR whenever a process instance created, u can save it in ur custom db or somewhr. U can get it from the task created to HR Role
