The largest value integer can store on Appian is 2147483646 and after that, it takes it back to negative. 
 Because you want to store 21 digits, you can use textField with length validation and another validation that makes sure the user is only entering numbers. 
 a!textField(
 characterLimit: 21,
 value: ri!value,
 saveInto: ri!value,
 validations: if(
 a!isNullOrEmpty(stripwith(ri!value,"1234567890")),
 {},
 "Value can only contain numbers"
 )
) 
 NOTE - You will also need to change the Datatype of your CDT field, Record field, and DB column to text.
