I think that I have covered everything

I have two tables

Parent Table

Child Table

I established the relationship in the DDT

Established to parentrelationship on the BO

Established the parent BO in the BO on the form.

Configured Childform.

In a nutshell, my applications has 3 forms and my parent relationship call was not at the highest form.

This is what I had.

Mainform

Contains a datagridview with a mainBO. From the Mainform, I have a childdialog calling the sub Entryform with the mainBO.

Entryform

This form contains the mainBO and childbo.

I had the parentchild relationship established in the Entryform.

ChildEntryform

Contains the childbo

When I moved the childbo up to the Mainform and established the relationship there, all the relationships worked.
