The Store module must be implemented before the History module can be used. Obviously to record sales history details the Sell module must be in use, and to record purchases the Buy module must be implemented.
Sales and purchasing details are read across automatically from the sell and buy modules, but the stock movement history must be transferred from the Store module using the Store module’s transfer transactions option. This option should be run on a regular basis.
Once some movement history has built up you can use the ABC analysis report to automatically ABC code your stock items - this can give you a greater degree of control over your stock.
