Step-1

Add a validation inside the HomeProductStockController.Js>SaveProductStock method. Validation is given below.

for (var i = 0; i < $scope.ProductStockList.length; i++) {
                if (($scope.ProductStock.ProductQtyId <= 0 || $scope.ProductStock.ProductQtyId == "" || $scope.ProductStock.ProductQtyId == null || $scope.ProductStock.ProductQtyId == typeof undefined) && $scope.ProductStockList[i].ProductId == $scope.ProductStock.ProductId && $scope.ProductStockList[i].BatchId == $scope.ProductStock.BatchId) {
                    alert("You can not select same product,batch again! Please change batch")
                    return false;
                }
            }

Step-2

We will use the same method to Save and Update ProductStock so that’s why we need to add another JS method which we will call when click on edit button.

        $scope.SetForEdit = function (item) {
            $scope.ProductStock = item;
        }

Now run the code and lets see its working perfectly.
