How to change Extension -->Case, Status Reason to 'Active' ?

I am working on a Dynamics CRM 4.0 version.  Where I have update some attribute values. But the case or incident is 'Resolved' or 'Problem Resolved' I cannot update using ETL package.

How to first I change the Status to 'Active' or 'In Progress’.. ?  Once it is active I can update the required field..

My ETL source Pass is  like this..

SELECT b.incidentid, 1 AS statuscode, 'In Progress' AS statecode

FROM System_Case_Type a

INNER JOIN WS40DYPSQ002.TELUSCMSS_MSCRM.dbo.IncidentBase b ON

a.Case_ID = CAST(b.incidentid as nvarchar (255)) COLLATE Latin1_General_CI_AI

WHERE a.Case_ID = 'D97279C1-6A32-E211-90D1-0025B5C1AA2F'

Where 'System_Case_Type ' os my local table and 'IncidentBase' is the CRM entity.
