Limit Shipping Method List

There are instances when an account have a long list of available shipping method, though there are only several methods that are usually used.

In this type of scenario, the user may wish to limit the shipping methods that they see in the list.

Since the list set on the Shipping Method field could not be directly limited, one can make use of the alternate solution below:

1. Create a custom list via Customization > Lists, Records, & Fields > Lists > New

• • Name: <desired name>
  • Values > Value: <Name of the desired shipping method>

2. Create a custom transaction field via Customization > Lists, Records, & Fields > Transaction Body Fields > New

• • Label: <desired name>
  • Type: List/Record
  • List/Record: <list in step 1>
  • Applies To: Sales
• Display tab: 
  • Subtab: Shipping
  • Display Type: Normal
• Store Value: checked

3. Create a Client side script triggered on field change

//set the actual shipping method based on the selected value from the custom list
define(['N/record'],
function(record) {‌
  function fieldChanged(scriptContext) {‌
    log.debug('name', scriptContext.fieldId);
    if (scriptContext.fieldId == 'custbody24')
    // custbody24 is the internal ID of the field in step 2
    {‌
      var custMethod = record.getValue({‌
        fieldId: 'custbody24'
      });
      log.debug('custMethod', custMethod);
      var shipMethod;

      if (custMethod == '1') // if - else was used since switch is not working
      {‌
        shipMethod = '1465'; // internal ID of the shipping method
      } else if (custMethod == '2') {‌
        shipMethod = '248';
      }
      log.debug('shipMethod', shipMethod);
      record.setValue({‌
        fieldId: 'shipmethod',
        value: shipMethod,
        ignoreFieldChange: false
      });
    }
  }
return {‌
  fieldChanged: fieldChanged
};
});

function clientFieldChanged(type, name, linenum) {‌
  nlapiLogExecution('debug', 'name', name);
  if (name == 'custbody24') 
  // custbody24 is the internal ID of the field in step 2
  {‌
    var custMethod = nlapiGetFieldValue('custbody24');
    nlapiLogExecution('debug', 'custMethod', custMethod);

    var shipMethod;

    if (custMethod == '1') // if - else was used since switch is not working

    {‌
      shipMethod = '1465'; // internal ID of the shipping method
    } else if (custMethod == '2') {‌
      shipMethod = '248';
    }

    nlapiLogExecution('debug', 'shipMethod', shipMethod);
    nlapiSetFieldValue('shipmethod', shipMethod, false);
  }
}
