help on expression?

Hi Members,

could u pls help on following query?

my input data:

UpDatedDate	DocID	DocStatus	Team	Client	ServiceType	DocumentType	ProcessorName	Profile
10/24/2013 8:18	00004590	Processed	Team1	Client1	ServiceType	DocumentType	A	A
8/1/2013 5:39	00004591	Processed	Team1	Client1	ServiceType	DocumentType	B	A
8/1/2013 6:39	00004591	Processed	Team1	Client1	ServiceType	DocumentType	A	A
8/2/2013 5:58	00004592	Processed	Team1	Client1	ServiceType	DocumentType	A	A
8/2/2013 6:58	00004592	Processed	Team1	Client1	ServiceType	DocumentType	A	A
8/3/2013 7:58	00004592	ERROR	Team1	Client1	ServiceType	DocumentType	C	E
8/3/2013 8:58	00004592	Processed	Team1	Client1	ServiceType	DocumentType	B	A
8/3/2013 9:58	00004592	Completed	Team1	Client1	ServiceType	DocumentType	A	A
8/2/2013 6:11	00004593	Processed	Team1	Client1	ServiceType	DocumentType	B	A
8/2/2013 6:14	00004594	Processed	Team1	Client1	ServiceType	DocumentType	A	A
8/3/2013 6:17	00004595	Processed	Team1	Client1	ServiceType	DocumentType	B	A
8/3/2013 6:20	00004596	Processed	Team1	Client1	ServiceType	DocumentType	A	A

Need to calculate Number of documents are Processed first time(DocID:00004592 processed two times in same day need first processed record at 8/2/2013 5.58 as part of count) (based on datetime of UpDatedDate &DocStatus fields) by UpDatedDate,DocID,dOCStatus,Team,Client,ServiceType,DocumentType,ProcessorName and Profile.

Any help? seems to be we can do by using FirstSortedValue function in expression on table level,but not succeeded.

Thank u...

noconcatenate

TempChangeOrderTable:

load * resident Table order by DocID asc, UpDatedDate asc;

noconcatenate

First update:

load * resident TempChangeOrderTable where previous(DocID) <> DocID;

drop table TempChangeOrderTable, Table; //Table is the original inputtable from data source, so change it both here and in the first load.

Now you will only read the first line for every DocID.

what is your expected output for the example in your OP?

I'm not 100% clear what you are asking. Do you want to cound how many documents have a single DocStatus for a given day?

If so I would:

- Create a date field that is a day, without time (using floor() or similar)

- Perform an aggr(count()) over DocID and date where DocStatus = Processed

- Add an 'if' clause if you just want to see where there is 1 in the day.

sol:

exp on dimension tab:=Date(Aggr(FirstSortedValue(UpDatedDate,RecID),DocID),'YYYY/MM/DD HH:MM:SS')

exp on expressions tab: =FirstSortedValue(Total DocID,-UpDatedDate)

thx guys for your help
