create a new field in script using last but 1 status

hopkinsc — Mon, 08 Sep 2014 09:29:45 GMT

Hi all,

i have a field named Order_Status_Name which holds the status of an order. an order would have multiple status and the majority of them would have a final status of 'Removed From Screens'.

I want to create a field that would have the value BEFORE the removed from screens value.

i.e.

Order ID	TimeStamp	Status
1001	01/09/2014 10:41	Generated
1001	01/09/2014 11:58	Job Started
1001	01/09/2014 14:23	Job Complete
1001	01/09/2014 23:54	Removed From Screens
12411	02/09/2014 06:12	Generated
12411	02/09/2014 09:33	Job Started
12411	02/09/2014 09:39	Specialist Required
12411	02/09/2014 23:54	Removed From Screens
12721	02/09/2014 15:21	Generated
12721	03/09/2014 09:52	Cancelled
12721	03/09/2014 23:54	Removed From Screens
12935	03/09/2014 11:49	Generated
12935	03/09/2014 11:49	Job Started
12935	03/09/2014 16:05	Job Complete

so the new field values would be:

1001 = Job Complete

12411 = Specialist Required

12721 = Cancelled

12935 = Job Complete.

I basically never want to see the status 'Removed from Screens'

Can anyone help me put that into the script please?

If you want only 4 rows at the end of the script use below

Timestamp#(TimeStamp,'DD/MM/YYYY hh:mm') as TimeStamp,

Order by is only possible in resident load. so first load without order by and then load resident with your order by and drop the first table

Addition to what Michael Replied....

You forgot ; after TIMETAG

It should be

Order By OrderID, TIMETAG;
