Does JDE allow to delete a customer from address book (and customer master) ??

Hi All

In JDE 9.2.5 , does JDE allow deletion of a customer record ?

Is there an in-built validation on open SOs/open Invoices before allowing for deletion?

In my system , there is a situation where some customer records were deleted (a human error). There are open SOs , open invoices against those customers across multiple business entities.

In this case , is there any standard JDE table where the record of those customers could be found for restoration? We're already checking internally at database level for the same

Please share your thoughts

Thanks in advance
