Successfully calling Add updates LastModified.

If you call Add with a LineItem that is similar to a LineItem that is already in the LineItemCollection, the behavior depends on the value of the lineItemRollup parameter. If the value of lineItemRollup is true, then the Quantity attribute of the LineItem object that is already in the LineItemCollection is increased to reflect the additional quantity being added. If the value of lineItemRollup is false, then the new LineItem is appended to the LineItemCollection.

Note

For the purpose of the preceding paragraph, one LineItem is similar to another if the ProductCatalog, ProductId, and ProductVariantId members of the two LineItems are the same.

This method does not clone the new line item prior to adding it to the collection.

Calling Add will set the ParentOrderForm, OrderFormId, OrderGroupId, and Index properties.
