* Record Types are a capability that enables the use of custom fields, contextual validation rules, and varied layouts for different types of campaigns. A record type is a way to offer different business processes, picklist values, and page layouts to different users based on their profiles. By creating record types for trade shows and customer webinars, Cloud Kicks can track different details for these types of campaigns by using custom fields, such as location, budget, attendance, etc. Cloud Kicks can also enforce contextual validation rules, such as requiring certain fields or values depending on the record type. Cloud Kicks can also display varied layouts for each record type, such as showing or hiding certain fields or sections based on the campaign type.
