Well I would think it might make sense under some circumstances to allow issue of the stock for nominal purposes for advertising and promotion for example where there are giveaways - these could come from any stock category.
I was hoping this functionality may have allowed for choosing the GLcode but it looks like it is just a static GL code with a selectable "tab"
