Hi Ratnesh,
ISBLANK - If an expression has a value and returns trueif it does not. If it contains a value, this function returns false . Text fields cannot be null. So use mainly for text fields.
ISNULL - If an expression is null (blank) and returns true if it is. If it contains a value, this function returns false . Numeric fields cannot be blank. So use mainly for numeric fields.
