One To Many Relationships
Forgive me; but I'm extremely new to Access. I've created a Table "T-Customer" and have the Key as "CustomerID" and have created a table called "Inventory" with an "InventoryID". From these tables, I've created a Query with a One-To-Many relationship "One" Customer to "Many" Inventory and then have created a Master Form with Customers and a Subdatasheet with Inventory. When I click on "Add Inventory", a child form pops up- but doesn't automatically populate the "CustomerID" in the Child Form. I just need to know how to make this happen and I'm afraid I'm overthinking it...
Normally you wouldn't display the parent ID, and just Access manage this in the background

I apologize Kevin, but I'm not quite sure what you mean?

The inventory form actually is an actual policy list; hard to explain- but each is different. So I gave them Keys as they may have to be edited.
OK, I may have misunderstood how you've designed your forms - using subdatasets (which I have never used) rather than subforms. With a subform, you define the parent/child relationship so that the sunform inherits the ID of the parent form automatically. This is a property of the subform (I assume that a subdataset also has properties). Once this is set, Acess will manage that for you.

Probably no real way to understand my madness! The main form does have a subform that outlines the "Jist" of the other form. Is there a way I can send it to you? I'm sure if you could see it, it would make sense.
You should be able to upload it here

I just sent it via email on here.
Replied, although you should always post examples etc here rather than as a message to an individual

I've attached a slimmed down version. PLEASE remember, I'm so new to this. I'm sure I've made some errors.

Looking at F_ClientSetup, you've correctly set the Parent Child.
Did you try closing and reopening to see if the ClientID was populated afterward. I don't think it is, until Access saves the record (after you move off it - or close the form.

Generally, you wouldn't add this column onto the form - there's no point in seeing it (other than to add to your anxiety). You will know it from the parent (if you need it at all). I prefer to leave it off, or at least make it non visible so as not to confuse people.

I did? YAY!!! I did close out of the form, closed out of access and then went back in and it didn't work. I also did the [Forms]![F-ClientSetUp]!Cl
ASKER
So if I leave it off both forms, how would the child form be affected? Because the Child form is extremely specific to the parent form.
