\nDescription: This report will delete a computer object from the SMS database. Use this report if you restage a computer with the same name. Normal process will take more than 30days to age to stale the record.

Save the the mof code above to a text file with file name like delete.mof. Start the Systems Management Console and scroll down to Reporting and click Reports. Right click Reports; go to All Tasks and click Import Objects. Browse to the delete.mof file to import the report. After you the delete.mof file has been imported; start IE and open the SMSReporting website. New category should be available like Networknet-LocalIT tasks. If you want to change this go to the SMS console and change the category name.
 Step 1 is finished now. The report is created. Next step is to extend the SMS database with extra stored procedure. Copy the text below to a text file named sp_delete.sql. Please change the SMS_ABC to your 3code Site name.

USE [SMS_ABC]

-- Description: Stored Procedure for deleting computer from SMS database by SMS Reports
-- =============================================
ALTER PROCEDURE [webreport_approle].[sp_RemoveComputerObject1]
-- Add the parameters for the stored procedure here
@Machinename varchar(15)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

-- Insert statements for procedure here
--SELECT * from system_Data where Name0=@machinename
delete from system_Data where Name0 =@machinename
--SELECT * from system_DISC where Name0=@machinename
delete from system_DISC where Name0 =@machinename
--SELECT * from system_Hist where Name0=@machinename
delete from system_Hist where Name0 =@machinename
--print @machinename + ' has been deleted from SMS database'
select @machinename as 'Deleted'
END

Login to your SQL server which hosts the SMS_ABC database and open SQL Query Analyzer tool. Open the sp_delete.sql file and execute the SQL (F5 short key).
Step 2 is completed now. Stored procedure has been created. Before the report will work for the reporting users the internal role webreport_approle will need to be granted with select and delete permissions on the SMS database tables.
These tables were granted with select and delete to webreport_approle. This is my test environment and I didn’t extend the SMS schema.

Save the code above to sql_grants.sql and execute the file in SQL Query Analyzer. Now you are ready to delete a computer object. Select one computer and run the report.
If the report is providing you an error message; most probably the stored procedure is trying to delete the data within SMS tables where the SMS Reporting user role has no permissions.
Go back to SQL Query Analyzer and grant the permissions. E.g.

grant select,delete on object::TABLENAME_DATA TO webreport_approle
grant select,delete on object::TABLENAME_HIST TO webreport_approle
