How to Import invoices tied to Subprojects
Trying to import open AR (invoices) tied to subprojects via CSV but receiving errors. When I use the parent project (customer : project name) as the customer, I receive an error "invalid entity reference key". If I use just the the customer in the parent project, I receive an error "invalid job reference key". I tried with the internal ID for both scenarios but received the same error. I verified all three entities belong to the same subsidiary, class and location, they also have the same currency.
If I check Sales > Projects tab of the customer of the parent project, I only see the parent project.
