Too many output arguments.

Compare:
Sis(73).Slipp = 'example';
[Sis.SlippSource] = testfun();
function output = testfun()
output = 123;
end

Sis(73).Slipp = 'example';
[Sis.SlippSource] = deal(testfun());
whos Sis
function output = testfun()
output = 123;
end
Your Sis is a 1 x 73 struct. When you use [Sis.SlippSource] = SlippSource(2) then SlippSource(2) would have to be an expression that returns at least 73 output arguments.
Remember, when you have a non-scalar struct A then [A.B]=C is equivalent to coding [A(1).B, A(2).B, A(3).B, ... A(end).B] = C; which requires that C has enough outputs.
If you want to assign the same value to a particular field in each entry in the struct, then use deal like I show here.
