Hi,
I have a master table called ventas that I want to update based on a lookup table called producto, the field to combine datasets is cod_producto.
I want to update the rows of ventas in which ventas.cod_producto = productos.cod_producto I am doing a set + modify key= and it doesn't work.
This is the code:
%let fecha_ini = %sysevalf(%sysfunc(date()) - 900);
%put fecha_ini = &fecha_ini;
/* Crearting dataset ventas */
data ventas(drop=i);
do i=1 to 10000000;
fecha = &fecha_ini + round(900*ranuni(1));
cod_producto = compress('P'||(round(ranuni(1)*1000)+1));
cod_centro = compress('C'||round(ranuni(1)*100));
hc_unidades = round(ranuni(1)*9) + 1;
format fecha ddmmyyn8.;
output;
end;
run;
/* Crearting dataset ventas */
data productos(drop=i);
do i = 1 to 1001;
cod_producto = compress('P'||i);
hc_precio = round(ranuni(1)*400) + 100;
output;
end;
run;
/* Updating datasets ventas */
data ventas;
set productos; /* lookpup */
modify ventas key=cod_producto; /* master */
if _iorc_ = 0 then do; /* hay coincidencia */
hc_ventas = hc_unidades*hc_precio;
end;
else do;
hc_ventas = 0;
end;
run;
The error:
'No defined variables for file ventas'
Can anybody help me??
Thanks in advance
