Hello,
I have a custom field that I had created for two different entities that have the same exact logic; the difference being that one loads on a list view while the other one never does unless you filter down to one instance. I have tried simplifying the logic as much as possible, but no matter what I am faced with the same issue.
Custom Field Logic:
Arguments: CUSTOMER_NO
SELECT EMAIL FROM CUSTOMER_INFO_CONTACT_BASIC
WHERE CUSTOMER_ID=:CUSTOMER_NO
FETCH FIRST 1 ROWS ONLY
Entities:
CustomerOrder and OrderQuotation
Customer Orders Page:

Sales Quotation Page:

Thanks,
