Support for Entity Identification
The Entity Identification custom record can be used to store the identification data for customer, vendor and subsidiary. For adding entity identification number in customer record, go to Lists > Relationships > Customers or Lists > Relationships > Vendors or go to Setup> E- Document > Electronic Invoicing Preferences under Entity Identification subtab. You can select a code from the ICD list (ISO 6523 ICD list https://docs.peppol.eu/poacc/billing/3.0/codelist/ICD/) and manually enter values for the Company Identifier. This custom record stores the full list of ICD codes, including each code, title, and description.
