Difference between NOdup and NoDupkey..??

[Mona1]

hi,

I am havig the following dataset

Customer Month      Type    Amount

A1        03JAN2004 PETRO 2000

A1        03JAN2004 PETRO 2000

A1        12JAN2004 JEWELLWERY 1000

A1        12JAN2004 JEWELLWERY 1000

Iam not getting the code for taking the duplicate values out in a separate dataset. Iam using this code

Proc sort data=valid_cards1 nodupkey nodopout=duplicates;
by customer month type amount;
run;

 Can anybody help?

Thanks & Regards

Mona

NODUPKEY option: Deletes observations with duplicate BY values

DUPOUT= option: Specifies the output data set to which duplicate observations are written.

I think your code has some misspelling and should be as this:

data valid_cards1;
input Customer$ Month:date9. Type$ Amount;
format Month date9.;
datalines;
A1 03JAN2004 PETRO 2000
A1 03JAN2004 PETRO 2000
A1 12JAN2004 JEWELLWERY 1000
A1 12JAN2004 JEWELLWERY 1000
;

Proc sort data=valid_cards1 nodupkey dupout=duplicates;
by customer month type amount;
run;

See the available options in the documentation here

Try
Proc sort data=valid_cards out=valid_cards_clean dupout=duplicates nodupkey;
By customer month type amount;
Format month date9.;
Run;
