You are missing quoting from   %if %upcase(&a) in (FI BI CA) %then %put Hello;

Try : %if %upcase(&a) in ('FI','BI','CA') %then %put Hello;

[Quentin]

This accepted solution looks wrong to me.  You shouldn't need quote marks in the macro language, as shown in the log I posted showing that the original code posted in the question works correctly.

[PaigeMiller]

I agree, @Quentin . The solution marked correct, in fact is not correct. 

@learn_SAS_23 Please un-mark that solution as correct.

[PeterClemmensen]

Remember to use the Options Minoperator.

[Quentin]

Your code runs fine for me:

1    %macro test(a) /minoperator;
2
3    %if %upcase(&a) in (FI BI CA) %then %put Hello;
4    %else %put ERROR;
5    %mend test;
6
7    %test(FI)
Hello
