What do validation errors and import warnings mean?

This article explains the difference between validation errors and warnings that can come up during an import and what they mean.

Validation errors

Validation errors appear in red and prevent the invoice or debtor in question from being imported from the accounting package. In almost all cases, this must be corrected in the bookkeeping. 

Below you can read what validation errors mean and how to fix them.

'Due date'

With this error message, the invoice and/or due date must be adjusted in your accounting package. In most cases, this error message occurs when the due date is earlier than the invoice date.

'Address details incomplete'

The message 'Address details are incomplete' means that you need to change and/or complete certain address details in your accounting package. The error message tells you what is incomplete or incorrect, so that you can change it, for example:

• Address can't be blank
• City can't be blank
• Postal code is invalid
• Email address can't be blank

Is the address abroad? Then it is important that the country code is correct. We use the ISO Alpha-2 codes for this.

'Customer number has already been taken'

To keep records as orderly as possible, it is important that the customer number is unique. This is usually caused by a change in accounting that has altered the underlying ID. In most cases this can be corrected by Payt, please contact the service desk to do so. 

'Invoice number has already been taken and origin_identifier has already been taken'

This error message appears when trying to import an invoice with an invoice number already existing in Payt. Invoice numbers must be unique. Causes could be:

• Renumbered or merged debtors that have not yet been renumbered in Payt

• Invoice numbers that are reused

'There is a new payment condition active on this invoice for which the follow-up has yet to be determined. Please contact the Payt service desk.'

This message appears when an invoice is loaded with a payment condition that is not yet linked to an invoice track in Payt. Is the payment condition provided from the accounting package correct? If so, the follow-up in Payt must be determined. Contact the service desk and let them know which flow the new payment condition should be linked to. When that is set, the validation error will disappear at the next import. 

Warnings

Warnings appear in yellow and are points of interest that have not blocked the import, but of which it is advisable to correct in your accounting package. 

Below you can read what the alerts mean and how to resolve them.

Probably a wrong number provided for phone calls or text messages (SMS)

During each import we perform a validation on provided mobile/phone numbers. When Payt registers a number as invalid, it will not be used for text messages or phone calls. 

The support article How does Payt verify phone numbers? explains the check that is performed on phone numbers in more detail. 

VAT number is invalid

We also do a validation on the VAT number (if provided). If our check shows that the VAT number is not valid, we issue a warning about it. It is important that the VAT number starts with the country code.

You can change the data in your accounting package. A subsequent import will upload the correct data.
