Thanks Robert Shankin ,
Thanks for your suggestion. I know this local variable concept but want to know that we can use that value property value by using any 'bang' or not.

What's your use case?

If the value of the field is hard-coded, the designer knows what it is, and there should be no need for a validation.

Assuming you use local variables defined in the interface load, you can then reference the save variable in the validation expression.

a!integerField(
  label: "Integer",
  labelPosition: "ABOVE",
  value: local!myInt,
  saveInto: local!myInt,
  refreshAfter: "UNFOCUS",
  validations: {
    if(
      not(isnull(local!myInt)),
      if(
        local!myInt<=100,
        "error",
        {}
      ),
      {}
    )
  }
)

for Example:

if the integerField value is greater or less than the value of integerField then it should be validate.

Consider below example,

a!integerField(

value: 200 ,

saveInto: ,

align: "LEFT",

labelPosition: "ADJACENT",

refreshAfter: "UNFOCUS",

validations:

if(value=<100,{},"validation message")

)

AFAIK, its not possible to implement validations without storing/holding a Value field.
Can you please explain your user case with more details.

Thanks,
