When you apply validations to both the fields themselves, and within a!formLayout's validations parameter, you will have error messages showing both underneath the field missing data, and at the bottom of the form. Is that not enough for your requirement? Note validation pop-ups are not available, but we can show any messages on screen.

a!localVariables(
  local!numberOfQuestions: 10,
  local!questions: 1+enumerate(local!numberOfQuestions),
  local!answers: repeat(local!numberOfQuestions,null),
  local!validations: reject(
    fn!isnull,
    a!forEach(
      items: local!answers,
      expression: if(rule!APN_isEmpty(fv!item),concat("Please answer question ",fv!index),null)
    )
  ),
  
  a!formLayout(
    contents: {
      a!forEach(
        items: local!questions,
        expression: a!textField(
          labelPosition: "ADJACENT",
          label: concat("Q",fv!item),
          value: local!answers[fv!index],
          saveInto: local!answers[fv!index],
          required: true
        )
      )
    },
    validations: local!validations,
    buttons: a!buttonLayout(
      primaryButtons: {
        a!buttonWidget(
          label: "Submit",
          submit: true
        )
      }
    )
  )
)

Recently, in a similar situation, I tried to just add a sectionLayout to each question. Each section did a check whether any value for that question was entered. This shows a red bar in case the validation fails. Maybe this helps.

Thanks Santander for your suggestions, I tried them out. But looks like validations makes sense only when we answer the ques. My use case is - if I miss answering any of the question, how to handle it immediately. It is also fine if I can get any kind of popup with the missed items while submitting the form.

Thanks Peter.!! I agree but most of the answer fields are of type text area with minimum length of 1000 characters. So in this case I dont think wizards are good option. Things apart, it is business requirement.
Can you help me with any other options ?

I'd also highly recommend using a wizard pattern if you have a long form. It's usually good practice to ensure your form is short enough that scrolling is not required for exactly this reason, and creating a wizard can ensure that you have multiple shorter pages.

You can define specific validations for each component (see https://docs.appian.com/suite/help/21.1/recipe-use-validation-group-for-buttons-with-multiple-validation-rules.html for an example), as well as for forms, sections, and editable grids (see https://docs.appian.com/suite/help/21.1/Validation_Message.html). Using those would allow you to show the validation messages right where you want them.
