> Yes, in the final table. 

Correct me if I'm wrong but this

 

%macro default;
%do i = 1 %to 12;

data pd.default_contratos_&i (rename=estado_cliente=estado&i drop = t compress = yes);
set pd.default_contratos /*(obs=10)*/;
fecha=t-&i;
run;

proc sql;
create index
nupfec on pd.default_contratos_&i(nup,fecha);
quit;

data pd.tabla_cliente_ (compress=yes);
set output.tabla_cliente_;
set pd.default_contratos_&i (keep= nup fecha estado&i) key = nupfec / unique;
if _iorc_ > 0 then do;
_ERROR_ = 0;
call missing(estado&i);
end;
run;
;

%end;
%mend default;
%default;

 

looks like the same logic as 

 

proc sql;
  create index NUPT on pd.default_contratos(NUP,T);
quit;

data PD.TABLA_CLIENTE_ (compress=yes);
  set OUTPUT.TABLA_CLIENTE_ ;
  array ESTADO_[12];
  FECHA=T;
  do T=1 to 12;
    T=FECHA-I;
    set PD.DEFAULT_CONTRATOS(keep= NUP ESTADO) key = NUPT / unique;
    ESTADO_[I]=ESTADO;
    if _IORC_ > 0 then do;
      _ERROR_ = 0;
      ESTADO_[I]=.;
    end;
    output;
  end;
run;

 

Am I wrong?

Once we have all the logic in a single data step, we can look at shrinking the lookup data and using a hash table.
