Invoke Processing Constraint Validations from PLSQL

Oracle EBIS Application : 12.1.3

DB : 19.0.0.0.0

Requirement : API required to validate if order attribute(like ordered quantity) is still eligible to be changed in a given order line.

Existing Validations : System has some seeded and custom processing constraints already added to prevent changes on order attributes . These validations gets triggered when user tries to do the changes using Sales Order Workbench or by calling Process Order API. But our requirement is to expose these validations to external applications through an API so that external application can prevent the changes on certain attributes based on these validations. Existing Process API doesn't work in our case as it requires users to pass new values to order attributes for which the validation is expected to be triggered.
