You can't change dimensions or data types, but you should be able to change structure tag values. So I don't know why the code is not working for the OP (we don't see his common block). But the following works

pro test1
common var,a
a.b(*,*) = 2500
return
end

pro test
common var,a
a = {b:dblarr(3,5)}
test1
print,a.b
return
end

IDL> test
2500.0000 2500.0000 2500.0000
2500.0000 2500.0000 2500.0000
2500.0000 2500.0000 2500.0000
2500.0000 2500.0000 2500.0000
2500.0000 2500.0000 2500.0000
