This option is Micronet's global price update facility. You can use it to recalculate buy prices and/or sell prices for all items or for a specific range of items. For example, if you receive a new price list from a supplier, you can use this option to update the buy prices for that supplier throughout Micronet. You can also use it to update your sell prices based on the new buy prices.
Alternatively, you can use it to create a new pricing structure. For example, you could copy all your old Buy 8 prices to a new Buy 7, etc.
You create global price updates in a batch that can be reviewed and amended before processing. This allows you to enter all the price updates, print a report to check them, amend them if necessary, and then run the price updates when you are ready (e.g. on a specific date).
