Hello Team,
I am dealing with multiple datasets in one of my program, Recently I added one dataset which dont have column used in merge operation earlier. So I added empty column as below
proc sql;
create table Emfuleni.GroupCodeTemp as
select '' AS Ward_Description, wGroup, szAccountNumber
from db.GroupChange
WHERE wClientCode = -10023 ORDER BY szAccountNumber;
quit;
DATA GroupCode;
SET Emfuleni.GroupCodeTemp;
BY szAccountNumber;
IF FIRST.szAccountNumber THEN count=1;
else count+1;
IF count>2 THEN delete;
drop count;
RUN;
In above query Ward_Description is empty column added. Now I am using this dataset in one of merge operation as below
data Emfuleni.lastjoin;
merge Emfuleni.ptp Emfuleni.masterward(in = a where = (open eq 1)) Emfuleni.Arrears Emfuleni.groupcode ;
by Ward_Description szAccountNumber;
if a;
run;
But i am always getting error as below
ERROR: BY variable Ward_Description is not on input data set EMFULENI.GROUPCODE.
Can someone please assist me what going wrong here ?
Thanks In Advance
Since you are using this code:
DATA GroupCode;
SET Emfuleni.GroupCodeTemp;
BY szAccountNumber;
IF FIRST.szAccountNumber THEN count=1;
else count+1;
IF count>2 THEN delete;
drop count;
RUN;
I suspect that this line
merge Emfuleni.ptp Emfuleni.masterward(in = a where = (open eq 1)) Emfuleni.Arrears Emfuleni.groupcode ;
refers to an earlier version of the data set Emfuleni.groupcode and you mean to use either:
merge Emfuleni.ptp Emfuleni.masterward(in = a where = (open eq 1)) Emfuleni.Arrears Groupcode ;
or to name the data set Groupcode as Emfuleni.groupcode.
With your Ward_Description as all missing (blank) in Groupcode I suspect that your results may not be what you want for the LastJoin.
