Specific Function Guidelines

• TEXT - TEXT() function MUST NOT be used with Text fields, to fix this you can just remove the TEXT() function.
• CASE - In salesforce CASE() function, last parameter is the default value. Admins often miss to provide this and number of parameters to CASE() function are always even.
• VALUE - VALUE() function should only be used with Text fields. If a number is being used as a parameter to the VALUE() function, remove the VALUE() function.
• DAY - DAY() function should only be used with Date fields. If a Datetime field is being used as a parameter to the DAY() function, convert it into a Date first.
• MONTH - MONTH() function should only be used with Date fields. If a Datetime field is being used as a parameter to the MONTH() function, convert it into a Date first.
• DATEVALUE - DATEVALUE() function should only be used with DateTime fields. If a Date is being used as a parameter to the DATEVALUE() function, remove the DATEVALUE() function.
• ISPICKVAL - If checking equality of a picklist type field, the function ISPICKVAL() MUST be used.
• ISCHANGE - Use ISCHANGE() function to check the value of a record has changed.
