Can you link a Table's Primary autonumber key to more than one Table's Foreign key?
I have a "ProductT" table which links via its Primary key to a Foreign key in the "ProdLineItemT" Table (which contains the product's Bill of Materials).
I also have a "LineItemT" Table which contains the sale products in the Sales Order Table. I want to link the Primary key of the ProductT Table to the LineItemT foreign key  as well.
Is it OK to do this, or can a Primary Key only link to a Foreign key in one other table?
Any advice appreciated!
