The Required fields based on the option app would ensure that agents fill the non-required ticket fields of a ticket when they create a ticket or update the ticket properties. You can customize which fields need to be made mandatory. ​ For example : 1.‘Type’ field can be configured as mandatory when the status of the ticket is closed or resolved. 2. Update a specific field only if the product is "xyz". Although the information required for every ticket might be different, with this app — by pre-determining the field requirements — you enable agents to enter the correct and relevant ticket details. Limitations: 1) The app supports only the Reply event. 2) There is no check for page specific fields in the app. For example, in the New Email page, agent and product fields are not present, but if the product field is configured, it will still show an error message prompt to fill the product field in the New Email page. The app will work in the following order : 1) First it will check the rules configured under reply ticket in Account settings if configured any.* 2) Next it will check for rules configured under dropdown fields. ** 3) Lastly it will check for rules configured under dependent fields.** * - For Reply click event only ** - For both Reply click event and ticket update / create button click. Note: 1) Zero (0) is a valid value for the Decimal and Number fields. The app will throw a validation error if the value is null or empty.
