Read Many to many relationship by Sadie W @ 8/16/2018
Work with contracts that have more than one project and projects that have more than one contract.  I've created and using a junction table, where I'm having trouble is, when an invoice for the contract is received, the payment is for one project or the other or split.  How do you record the invoice information when it's only tied to the contract?  Tried connecting it to the Projects table as well but that messed up entry on a form.

Do you have an example with some sample data to get a better idea of what you want to achieve.

Read How do I set of this Many to Many relationship by John G @ 12/27/2016
I am trying to establish a database where I can see who is in a class as well as all of the classes a student is in.  How would I go about setting this up?

Reply from Alex Hedley:

Do you have a StudentT, a CourseT then a StudentXCourseT JunctionT that stores which Student has enrolled in the Course?

Scott, you need to have multiple tables for this. One table should have information about your PEOPLE, and a second table should have your OTHER STUFF (whatever you're tracking) linked to this table by the ID. Review Access 201 for proper relational database techniques.

My database is used as a reporting system. At present when you enter a subject a subjID number is assigned (autonumber). Because a subject can be in many different occurences I have the subject info set up so that when you choose the last name from a combobox the remaining info autofills thus speeding up any data entry. The problem that I am having is that a SubjID number is being assigned to the person everytime you enter him/her. The very same person may have hundreds of of ID numbers. When I am searching for a subject I have no way of narrowing it down to just one entry. My question is : Is there anyway of having just one ID number for each person rather than several?
