how to validate an ap invoice through api or pl/sql package
I'm using api to import the invoice data to header and lines table
AP_INVOICES_ALL , AP_INVOICES_LINES_ALL .
Then i need to Validate the invoice , to make it as validated .
is there any api or pl/sql , that i can call from soa gateway or programmatically to perform the action of validation , instead of doing it from forms screens ?
