%LET M1 = MES1;
%LET M2 = MES2;
%LET M3 = MES3;

%LET ATUAL = MES1;

%IF &ATUAL. = &M2. OR &ATUAL. = &M3. %THEN %DO;
/*CODIGO*/
%END;

Escrevi uma estrutura assim, porém o SAS está entrando no código da condição, quando na verdade não era pra entrar, pois a variável "atual" não é igual a M2 e nem M3.

Estou desconfiando que ele não reconhece o OR na linha de condição. Não sei por que não está funcionando, parece ser muito simples.

Using %IF-%THEN-%ELSE in SAS programs in open code has its limitations like no nesting.

For your sample code

%LET ANOMES1 = mes1;
%LET ANOMES2 = mes2;
%LET ANOMES3 = mes3;

%LET M_ATUAL = mes1;
%macro doit();
%IF &M_ATUAL. = &ANOMES2. OR &M_ATUAL. = &ANOMES3. %THEN %DO;
	%IF &M_ATUAL.=&ANOMES2. %THEN %DO;
		/*sub code*/
	%END;
        /*REST OF THE CODE*/
%END;
%mend;
%doit();

The code you shared does what you expected. You must have gotten something wrong with your testing.

%LET M1 = MES1;
%LET M2 = MES2;
%LET M3 = MES3;

/* FALSE */
%LET ATUAL = MES1;
%IF &ATUAL. = &M2. OR &ATUAL. = &M3. %THEN
  %DO;
    data _null_;
      put "Condition True";
    run;
  %END;
%else
  %do;
    data _null_;
      put "Condition False";
    run;
  %end;

/* TRUE */
%LET ATUAL = MES3;
%IF &ATUAL. = &M2. OR &ATUAL. = &M3. %THEN
  %DO;
    data _null_;
      put "Condition True";
    run;
  %END;
%else
  %do;
    data _null_;
      put "Condition False";
    run;
  %end;

I think the problem is that I put another %if inside my %if, because when I commented it, the code worked (did nothing as it was supposed to)

Is there anything wrong with this structure?

%LET ANOMES1 = mes1;
%LET ANOMES2 = mes2;
%LET ANOMES3 = mes3;

%LET M_ATUAL = mes1;
%IF &M_ATUAL. = &ANOMES2. OR &M_ATUAL. = &ANOMES3. %THEN %DO;
	%IF &M_ATUAL.=&ANOMES2. %THEN %DO;
		/*sub code*/
	%END;
        /*REST OF THE CODE*/
%END;
