Simple, you are trying to make the association of a simple key with a composite key.
And both sides of the relationship should contain the same fields, remove the composite key from the table(Lyco_faltas) do the relationship and apply the key again, this should work.
Add the schema of the tables. Not knowing how they are, it becomes complicated to help.

I don’t quite understand your model, but there’s a way that you can connect with this modeling. Change your template by changing the primary Missing key only to Missing. Then you turn on Faults in Lica_faults by Falta_exp and then Lica_faults with Licao. It should work.
