There are two ways you can improve buyer identification (and hence the interpretation of invoices):
Add fields to identify buyers
Create buyer variations in the master data
The default fields used to identify buyers are Name1, Name2, NameSupplement1, NameSupplement2, and VATRegistrationNumber. You can add other fields to this list using the BuyerExtraIdentifierFields setting in Eiglobal.ini. You should only use this setting when you know that the field(s) you add uniquely identify a buyer.
Tip: Be careful if you use fields that have numerical values. Even though they may identify buyers, these values may also be found in other fields in invoices for other buyers. For example, the POBox value may be unique for each buyer, but these values may also be found in amount fields. A buyer may have the PO Box "20", but "20" may also appear as amounts or quantities on other invoices. In this case, the value for POBox cannot be considered as being unique for invoices for different buyers.
Note: When INVOICES finds more than one match based on any of the name fields above, it uses the PObox, Street, StreetSupplement, PostalCode, and City fields to determine the correct buyer. You can also use any of these fields in BuyerExtraIdentifierFields when they uniquely identify a buyer.
You can improve the identification of buyers by creating variations of the buyer entry in the master data. As the buyer name is not always printed and/or spelled the same on every invoice, entries in the master data to cover these variations helps INVOICES to identify the buyer.
For example, consider a fictional German buyer, Häckel und Weiss GmbH. The entry in the master data may be "Häckel und Weiss GmbH". Suppliers though may write this name differently, such as "Häckel und Weiss", "Haeckel und Weiss GmbH", or use others. The name may also appear as an entity name used internally, such as "Company 1234". If you add these variations to the master data, the buyer is more easily identified when processing invoices that contain these different names.
