Hi...I am trying to create a new variable ID1 based on variable ID. I want to assign the ID value where the status is 'Y' for the same address. The addresses with a status 'Y' represent the current ID for that particular address and there will only be 1 address with a status with a 'Y' and those with a status 'N' are previous and old ID. I can't seem to get my code to work. Thanks

proc sort data=list1;

by address_1 status descending;

run;

data list2;

set list1;

by address_1;

if first.address_1 then

ID1= ID;

else

ID1=lag(ID);

run;

Output:

Address_1	Status	ID	ID1
BOX 1700 34 FIRST ST SW	Y	P820	P820
#26 - 1313 BORDER STREET	Y	P535	P535

10 414 WESTMOUNT DR	Y	P282	P282

Since you are able to sort your data, the rest of the code would be simple. Note that DESCENDING comes before the variable name, so:

proc sort data=list1;

by address_1 descending status;

run;

data want;

set list1;

by address_1;

if first.address_1 then id1=id;

retain id1;

run;
