|#1186| simplified the copyfield function as now we are validating the stockonhand in rnrLineItem which previously was only happening at client side
|#1186| +RahulK| removed the default values hash to get values for rnrLineItem, instead getting values from initiated RnrLineItem, this was not working previously as mandatory field check on stockInHand was missing, which now is fixed, also removed unintended change from client side validation for stockInHand
