An example of a method inside of Aras Innovator that adds an item while using the doGetItem attribute

RequestWithDoGetItem.cs

Innovator inn = this.getInnovator();

Item newPart = inn.newItem("Part", "add");
newPart.setProperty("item_number", "New Part 1");
newPart.setAttribute("doGetItem", "0");
newPart = newPart.apply();

// You can still validate the response when using doGetItem
if (newPart.isError())
{
    // The item failed to be created, so handle that appropriately
}

// Otherwise continue as normal
return newPart;
