Change the dropbox field to a non-primary column in EditForm.
The main table is A, and the referencing table is B.
Let the primary column of B be b and the column to be looked up be w.
A(many) : B(1) and w is set as the lookup column.
The property settings for the app dropbox are as follows.
Edit field is changed from default column b to column w.
I want this setting to work without displaying an error message.
