Sets the number of line items for the journal. If the journal already contains line items, then the following rules apply:
If the new number of line items is less than the existing number of line items, then the applicable number of line items are deleted, with the last items deleted first. For example, if the journal has four line items and you pass 2, SetNumberOfLineItems deletes the third and fourth line items.
If the new number of line items is greater than the existing number of line items, the new line items are initialized to the data contained by the last of the existing line items. For example, if the journal has six line items and you pass 8, then SetNumberOfLineItems sets the seventh and eighth line items to the data contained by the sixth.
