as others requested we need a log from you.

my guess:

a library reference, libref,
does not allocate the library.
you must first use the libname statement,
of which libref is the pronoun
that you will later use to refer to the directory specification.

keyword libref=pronoun directory-specification
libname MyLibRef       'c:\temp';

so: macro A creates the libref MyLibRef
and you pass that libref
-- note: you said libname, which is incorrect  --
to macro B.

whatever value libref has it is only a string
which you are passing to/from macros.


%Macro A;
%Let     Libref = Temp;
libname &Libref. 'C:\temp';
%mend;

%Macro B(lib=);

Data &Lib..Test;

%mend;

%B(lib = Temp);

the above will work;
however, since macro A knows the value of libref
how do you think some other programmer will be able to figure out
that libref = Temp
has already been allocated.

It would be better to have macro B allocate its own libname and libref.
