Business validations - overview – ISPnext Helpcenter

During invoice processing the platform performs a series of checks: the business validations. If a validation does not pass, the platform displays a message on the invoice.

This article is the overview of all business validations. Each validation has its own article describing what the validation checks, when it fails and when it does not.

Two attributes are listed for every validation:

Technical Name - the internal identifier of the validation, for example validate_posting_date.
Availability - the ERP connection the validation applies to. Generic means the validation is available for all ERP systems. If an ERP system is named, the validation applies to that system only.

ℹ️

Info: Which validations are active in an environment depends on the configuration and on the connected ERP systems. Please contact your implementation consultant for questions about the configuration.
