CREATE TABLE IndustrialUnit (
UnitId NUMBER (7,2) PRIMARY KEY,
Location_place VARCHAR(50),
Country VARCHAR (50),
FOREIGN KEY (ProdId) REFERENCES Production(ProdId)
);

When I try to set the FOREIGN KEY, the following error occurs: ORA-00904: "PRODID": Invalid identifier.

You did not create the ProdId column in this table (IndustrialUnit). in addition this column must be of the same type and not null in the Production table. check.
