User exits for Argentina
With this user-exit it is possible to process warnings etc. if the invoice reference fields on item level are filled. Available are the billing document header and the billing document item. To access other tables like the document flow it is necessary to set up the billing
type in a way that the billing document is not posted to FI directly and change it afterwards. Then when changing this billing document it is possible to retrieve further information from the related database tables and - for example - issue a warning.
