validation message

Hi JS0001,

One suggestion here is that we can directly use the integer field. If there is a different constraint, I have added the code for validation for the text field you expected below.

{
  a!textField(
    label: "Text",
    labelPosition: "ABOVE",
    value: ri!text,
    saveInto: ri!text,
    validations: if(
      and(
        a!forEach(
          items: code(ri!text),
          expression: and(fv!item >= 48, fv!item <= 57)
        )
      ),
      "",
      "Enter a valid number"
    )
  )
}

Try this: 

a!localVariables(
local!a,
a!textField(
label:"Number Only",
value:local!a,
saveInto: local!a,
validations: if(a!isNullOrEmpty(stripwith(local!a,"0123456789")),"","validation"),
)
)

Hi, this works for integer data type, But in my case I have number(decimal) data type.If I use this validation it is not working for me,what to do?

In the case of decimals, use the decimal field component which has inbuilt validations to avoid text

https://docs.appian.com/suite/help/23.3/Floating_Point_Component.html

No, If I use floating-point component still not working,The value is vanishing if I enter 10k instead of giving 10

a!floatingPointField(
                /*label:"Face Value"*/
                value: rule!CR_FN_setDecimalValues(
                  value_dec: index(fv!item, "faceValue_dec", {}),
                  decPlace_int: 2
                ),
                saveInto: fv!item.faceValue_dec,
                readOnly: local!releaseDeleteReadOnlyBool,
                required: rule!CR_APP_FN_requiredConditionsForDocumentaionUnit(
                  crAppSelectedItem_cdt: fv!item,
                  role_txt: ri!role_txt,
                  isRequired_bool: ri!isSecurityCollateralReq_bool
                ),
                validations:{rule!CR_FN_setValueGreaterThanZeroValidation(value_dec: fv!item.faceValue_dec),
                if(a!isNullOrEmpty(stripwith(local!faceValue,"0123456789")),"","Enter a valid"),
                }
              ),

I have done like this,still it not working,Could you suggest?

 a!textField(
                /*label:"Market Value"*/
                value: rule!CR_FN_setDecimalValues(
                  value_dec: index(fv!item, "marketValue_dec", {}),
                  decPlace_int: 2
                ),
                saveInto: {
                  fv!item.marketValue_dec,
                  a!save(
                    fv!item.discountedValue_int,
                    rule!CR_APP_FN_getDiscountedValueFromMarketValue(
                      crREFCollateral_cdt: local!rowREFCollateral_cdt,
                      marketValue_dec: fv!item.marketValue_dec
                    )
                  )
                },
                readOnly: local!releaseDeleteReadOnlyBool,
                required: rule!CR_APP_FN_requiredConditionsForDocumentaionUnit(
                  crAppSelectedItem_cdt: fv!item,
                  role_txt: ri!role_txt,
                  isRequired_bool: ri!isSecurityCollateralReq_bool
                ),
                validations: {rule!CR_FN_setValueGreaterThanZeroValidation(value_dec: fv!item.marketValue_dec),
                if(a!isNullOrEmpty(stripwith(local!marketValue,"0123456789")),"","Enter a valid number"),
                }
              )

Let me ask you a question. Why do you want the user to enter something like "10k" instead of a real number like 10000? Or is that just you, abbreviating your writing here?

I have a hard time telling from the phrasing of the original post, but it almost looks as if to me as if they want to validate the user does NOT enter numbers like that.

No User has entered such type of value, They want us to provide validation.

I don't see any values saved to local!marketValue, which you have used in the stripwith function. In case of decimals, add a decimal point also in the with parameter value of stripwith function.
