What is best way to Choose Validation Rules for Incoming Invoice

[duke-nuke]

At start we were handling Invoice related to One country but as we are expanding we now are receiving invoices from different Countries
i was thinking what is best way to choose the Validation Rule for incoming invoice ?
do we pick based on DocumentTypeId and ProcessId
or incoming schemeId

Usually I recommending to use ddd for this. It can auto-detect certain elements from a source file, including the VESID. Alternatively, you can also make a list based on the combination od document type ID and process ID.

My proposal is:

• on the sending side, use a mapping based on Document Type ID and Process ID
• on the received side use "ddd" as you need to read the full document anyway

by using ddd can we choose validation rules on the fly based on incoming document ?
i looked into ddd look like its returning VESID from it we can create DVRCoordinate but
how i can i check which schematron to load in the registry ?
some static code still needs to be written ?

Usually you have a IValidationExecutorSetRegistry <IValidationSourceXML> vesRegistry object where you register all the rules that you support.
Via vesRegistry.getOfID (aVESID); you can check if the you support the VESID Or not.
Generally in Peppol you define what you receive and register these document types in the SMP. Therefore you should be well aware, what document types you are expecting -> make sure they are registred in the vesRegistry upfront. If you receive a document that you don't didn't register at the SMP, you can reject the message as "not serviced".
