Megaventory supports batch (or sometimes called lot numbers) - which are usually associated with the need to track expiry dates - in a limited manner.
As such, there are two workarounds to address this:
If you'd like to add batch information to your products you can use a field that exists in the Goods In/Out form when a products enters or exits your warehouse. Doing it this way, you can track batch numbers at the level of knowing when a specific batch number entered/exited your Inventory Location. For example, you may fetch the Goods In and Goods Out document(s) of a specific batch number. That alone will give you the date of enter/exit, the specific Inventory Location (or locations) and the supplier/client name.
The field to use is the Remarks field. You can enable it per document type. To enable the Remarks column, please navigate to the Document Types (click the Gear Icon at the top-right) . Once the list of documents loads, click on a document type (for example the Goods In) to edit its default definition. Once the page opens up, check to show Remarks and then Update/Save the Document Type definition. Repeat this process for the rest of the document types (for example SO/PO and Goods Out) that move items in/out of your location(s).
You may also localize the "Remarks" text to read "Batch No" through the Localization module (Localize Megaventory under your Admin menu).
Note however that this is a workaround and it does not work if you want to implement a FIFO approach or to track expiry dates (as in these cases the products have to be tracked inside the warehouse as well and not only when they enter/exit). A more complete support of expiry dates and batch numbers is on the road map.
Based on your business operations the following workaround may also be useful:
- Create each LOT/Batch as a distinct new product (say 0001-01, 0001-02 -or- 0001_2014-25-05, 0001_2014-25-03 etc.).
- Add those product in separate bin locations (from the on-hand inventory module)
