The cLineItems class controls the lineitems of a real invoice. The cTLineItems object handles temporary 'virtual' invoice lineitems - the two classes differ slightly in structure and use different data files, but otherwise share the same object interface.

This class is a little tricky to work with in that the invoice does not directly attach to this class. Instead Invoice uses a cItemList class which is a lightlweight class that only holds an array of SCATTER NAME objects and a count. This object can be generated by this class using LoadLineItems() and passed to an invoice.

This class also handles inventory updates on physical items through the Save and DeleteLineItem methods.

For clarity explict LoadItem and DeleteItem methods were added to differentiate between single record and multi-record operation. The single record operations are functionaly equivalent for Load() and Delete() in other classes.

The underlying table is wws_lineitems
