Creating a validation rule

Knowage supports the validation of the document’s input parameters via validation rules. Validation rules can be defined in Behavioural model > Constraints Management.

Contraints functionality.

A validation rule checks parameter values as given by LOVs to verify that they comply with the defined constraints.

Contraints Management Panel.

Knowage default checks are:

• Alfanumeric: it checks if the parameter is alfanumeric;

• Numeric: it checks if the parameter is numeric;

• Letter String: it checks if the parameter is a letter string;

• E-Mail: it checks if the parameter is an e-mail;

• Fiscal Code: it checks if the parameter has the correct syntax of a fiscal code;

• Internet Address: it checks if the parameter is an internet address.

• Max/Min Length: it lets you set the maximum and/or minimum character parameters length;
