D365 F&O Data Migration – Importing Contacts Without Associated Party Number

Posted on by RY-09121202-0

Hello everyone,

I’m currently performing a data migration for a D365 F&O ERP implementation. One of the requirements is to migrate all contacts that have an email address.

I’m aware of the ContactsV2 data entity, which would normally be suitable for this purpose. However, I don’t have access to the AssociatedPartyNumber, which is a mandatory field for a successful import.

Customer records are being imported through a separate integration process (which is outside my scope of work), so I don’t have direct access to that data.

My question is:

Is there any alternative approach to avoid having to export all customer data, retrieve the AssociatedPartyNumbers, add them to my import file, and then import the contacts afterward?

Thank you in advance for your help and insights!

Hi,

You will need to provide the correct party reference to import the contacts. As you mentioned yourself, you need to have an export of the customers with the linked party numbers to be added to your source file.

Use the Excel add-ins process and update directly in the table.
