A placeholder column is used to hold the value of certain calculation or a variable that is being carried out in a formula column. A place holder can be defined as anumber, character or date type, depending upon the type of value which will be stored into it.

A format trigger is used when we want to display a particular field, if certain conditions are met.

it return boolean-true then go to print.
