I suspect that it is the way that you have defined your disallowed combinations with ANDs between all the conditions. I don't think that it is defining the disallowed combinations that you intended.
I have broken out the conditions that you have linked with ANDs into separate lines to try and make more sense of it:
Suplier == "Finland"
& ("\!"Nazal\!" Amount"n == "160" | "\!"Nazal\!" Amount"n =="180")
& ("\!"Long-Short\!" fiber ratio"n == "80-20" | "\!"Long-Short\!" fiber ratio"n == "60-40" | "\!"Long-Short\!" fiber ratio"n == "50-50")
& (Unraveling time == "105" | Unraveling time == "120")
& (Sealing material percentage == "0.5" | Sealing material percentage == "1" | Sealing material percentage == "1.5")
Perhaps this way of defining the disallowed combinations works better:
(Suplier == "Finland"
& ("\!"Nazal\!" Amount"n == "160" | "\!"Nazal\!" Amount"n =="180"))
|
(Suplier == "Finland"
& ("\!"Long-Short\!" fiber ratio"n == "80-20" | "\!"Long-Short\!" fiber ratio"n == "60-40" | "\!"Long-Short\!" fiber ratio"n == "50-50"))
|
(Suplier == "Finland"
& (Unraveling time == "105" | Unraveling time == "120"))
|
(Suplier == "Finland"
& (Sealing material percentage == "0.5" | Sealing material percentage == "1" | Sealing material percentage == "1.5"))
Here each condition is separated with an OR.
See the attached Custom Design that was created with these disallowed combinations.
I would have some concerns about how useful this experiment is because most combinations are disallowed when Suplier = Finland. But again, maybe that is not what you intended.
It might help if you can state in words the nature of the disallowed combinations that you have in your experiment.
I hope this helps,
