How to make sublist field mandatory?

Question

This is my pageInit function

function poTransPageInit(type) {
    //   alert('page init');
    var field= nlapiGetLineItemField('item', 'field');
    field.isMandatory = true;
}

what I do wrong here?

Answer 1

It is true that the isMandatory method is not available in Client Scripts. As a work around you could get the field's value and check the length.

function validateLine(type){
  if(type == 'sublistInternalID'){ //sublistInternalID = sublist internal id, i.e. 'item'
    //get the sublist field value of mandatory column
    var name = nlapiGetCurrentLineItemValue('line', 'fieldId'); //line = line #, fieldId = internal id of field
    //if value length is greater than 0, then there is a value
    if(name.length > 0){
      return true;
    } else {
      alert('Please enter a value for Name field');
      return false;
    }
  }
}

Answer 2

field.isMandatory is SuiteScript 2.0. In SuiteScript 1.0, you would use field.setMandatory(true), but apparently that function is not available in client scripts.

You could try moving this logic to a User Event script.
