Cannot add foreign key constraint, i can't find the mistake - mysql

Question

I'm just starting with this, but when i imported my file to sql to beguin filling all the information, it shows me the error on the above, i know it's given because it's not the same length or the same type, so i tried to look for it on the plane code or the work bench and i couldn't find it. Any ideas?
I'll really appreciate the help.

I tested your script, and found the table Insumo failed to be created.
Then I ran SHOW ENGINE INNODB STATUS to get more detailed information on the cause of the foreign key failure:
------------------------
LATEST FOREIGN KEY ERROR
------------------------
2018-04-03 18:22:32 70000df33000 Error in foreign key constraint of table dhl_dummy/insumo:
FOREIGN KEY (`idInsumo`)
REFERENCES `dhl_dummy`.`Proporciona` (`Num_Art`)
ON DELETE CASCADE
ON UPDATE CASCADE)
ENGINE = InnoDB:
Cannot find an index in the referenced table where the
referenced columns appear as the first columns, or column types
in the table and the referenced table do not match for constraint.
Read the last sentence.
When you create a foreign key, you must match all the columns of the primary key in the table you reference. If the referenced table has two columns in its primary key, your foreign key must have two columns.
In your case, you tried to make a foreign key on one column idInsumo referencing the second column of another table's primary key.
FOREIGN KEY (`idInsumo`)
REFERENCES `dhl_dummy`.`Proporciona` (`Num_Art`)
But the primary key of Proporciona is two columns:
PRIMARY KEY (`Clave_Prov`, `Num_Art`),
You shouldn't create a foreign key that references part of that primary key.
I didn't test further, but I looked at the later table definitions and I see you have similar mistakes in several other tables. You're trying to make foreign keys from columns that don't match the whole primary key of the table they reference.
