Script > Get/Set value of sales rep from sales order with Team Selling Enabled

When Team Selling is not enabled the Sales Rep field shows up on the Body of the order and you could get/set the field by accessing the field id, please refer to the  script below :

var rec = nlapiLoadRecord('salesorder', xx); //xx is the internal id of the sales order

var salesrep = rec.getFieldValue('salesrep'); // Will give the internal id of the employee, In order to get the name use getFieldText

// To set the field value

var sales rep = rec.setFieldValue('salesrep',xx); //xx is the internal id of employee

When Team Selling feature is enabled Sales Rep field will disappear on the main body of the transaction and there will be a Sales Team tab created, populate the employee field here in order to set the sales rep.  Please refer to the script below :

var rec = nlapiLoadRecord('salesorder', xx); //xx is the internal id of sales order
rec.selectLineItem('salesteam',1);
rec.setLineItemValue('salesteam', 'employee',1, x); //x is the internal id of employee
rec.setLineItemValue('salesteam', 'salesrole',1, x); //x is the internal id of the sales role (Setup > Sales >CRM Lists)
rec.setLineItemValue('salesteam', 'isprimary',1, 'T');
rec.setLineItemValue('salesteam', 'contribution',1, '100');

nlapiCommitLineItem('salesteam');

nlapiSubmitRecord(rec,true);
