[MS_AccessPros] Many to Many relationship

 

Hello all,

After building the database for my client and a year of use we discovered that some information was not conveyed to me before I designed the database. The database tracks Management companies with the Home Associations related to the management companies. So I have a one to many for One Management company to many Associations. But I found out that an Association can change management companies at will.
Right now I have tblManagement in a one to many with tblAssociation linked on ManagementCoID in both tables with a one to one relation to tblProjects linked on AssociationID in both tables.

I know that I had set up primary keys for the tables yet somehow they are gone and the duplicates are set to ok for dups. Now we have multiple Associations in the table. I need some help.

How would I go about creating a many to many for the associations and management co tables?

Thank You

Jim Wagner
