handles.inputData.A is not the name of a scalar structure variable. It is an
expression that when evaluated returns a scalar struct array. Those are two
different things.

handles IS the name of a scalar struct array and so is acceptable for use
with the -struct flag.

D = handles.inputData;
save(filename, '-struct', 'D')
