Hi, its a nightmare not being able to add retrospective batch numbers. The system assumes that there is a constant stream of batch when there is more grey than black or white. It is a nightmare to change batch numbers retrospectively especially when you try to reimport batch details. Also when the items dont have batch tracking to them, when one tries to convert that item to a batch tracked item, the system wont allow anyone to do so. Please can you improve the batch tracking process so people can add batch data retrospectively and allow people to convert non-batch tracked items to batch tracked items without having to delete everything and it causes nightmare.
