Rules

ABBYY FlexiCapture for Invoices uses rules to validate invoices automatically. Upon validation, an invoice is assigned a status and a list of issued errors and warnings is generated, enabling the Operator to decide whether the invoice needs to be verified manually. While verifying an invoice in the document editor, the Operator sees the list of errors detected by the rules and can use this list to navigate and review the defective fields.

ABBYY FlexiCapture for Invoices already includes pre-defined validation rules for invoices commonly used in different countries (See Rules). Users can modify or remove existing rules and create new custom rules.

The instructions below are specific to creating rules in ABBYY FlexiCapture for Invoices.

1. After you have selected a rule type, you need to specify:
1. Name
   The name of the rule should reflect the kind of validation performed by the rule. Errors issued by the rule will be displayed to the Operator in the following format:
   Rule name: Error message.
   If you want the rule to affect the status of invoices, prefix its name with (Exception) or (Rejected), depending on the status you want assigned to an invoice if the rule detects an error.
2. Severity
   Severity flags help the Operator to review the errors and warnings and decide which invoices should be verified manually.
   Data export can also be made dependent on the severity flag. For example, you can:

• export documents that have no rule errors but have rule warnings to your working database
• export documents that have rule errors to an exceptions folder
• prohibit the export of document with errors altogether

For detailed instructions on setting up export based on the severity of a rule, See Rules.

1. Whether the rule should be enabled after it is created (Rule is enabled option)
1. In this step you need to specify the condition for applying the rule. Typically, this condition is defined by the value of the Invoice Layout\BU\Country field.
   By default, the rule will always be applied (Apply rule=always). If you want the rule to be applied only under certain conditions:
1. From the Apply rule list, select on condition.
2. Click Edit... to modify the condition.
3. Select the field whose value will trigger the rule (Invoice Layout\BU\Country).
4. Specify the condition and, if applicable, allowed and prohibited values.
   Example 1. The rule must be applied to German invoices.
   Select the Belongs to set condition, click Add, and add the value DE.
   Example 2. The rules must be applied to all invoices except German and French invoices.
   Select the Does not belong to set, condition, click Add, and add the values DE, FR.
2. In this step, you need to set up the rule. For detailed information, See Rules.
