The Stock -> Stock lots section contains a list of all stock lots that are either currently in stock or scheduled to arrive, plus the history of all stock lots in the system.
General advice about stock lots:
It is an internal business object in the MRPeasy software, usually created automatically, and used for providing the FIFO method for consuming goods, and also for some other functionality, like, for example, expiry date.
In your daily business, usually, you should not operate with these automatically created stock lots.
The Stock -> Stock lots page allows
- editing and viewing stock lots details,
- accessing reports of stock lots to see the history of each stock lot,
- looking up the source of each stock lot,
- manually adding goods to stock by creating a stock lot (normally, not recommended),
- moving items between internal storage locations,
- printing lot labels.

Tips and tricks
- Depleted stock lots are not shown by default. For finding them, search by lot number or filter by "0" total quantity.
The stock lot keeps the detailed history of each item that is processed in your company.
For example, each time you purchase a material, a new stock lot is created to identify it.
You may have many stock lots of the same item - purchased at different times, with different costs, possibly from different vendors, with different expiry dates, stored in different locations/shelves, some of which have certificates, files attached, or notes, etc.
Stock lots and batch tracking
Stock lot functionality can be used for batch tracking, as technically it provides traceability.
However, a stock lot is not always equivalent to a (manufacturing) batch number. For example, it may be that you receive goods from the same batch of products from your vendor in two deliveries - in this case, there will be two stock lots, created by the system.
When you wish to track some batch number, which is not equivalent to the stock lot number, you can act as follows:
- it is possible to encode the batch number in the stock lot number, e.g. by adding it as a suffix.
- it is possible to use a custom field to keep your batch number.
MRPeasy inventory management is designed for lot/batch and serial number traceability. Lot tracking helps to ensure that the history of every product and material is known. Technically this means the following:
- Each lot of an item is tracked and identified separately. Unique lot numbers are automatically generated.
- Every time a material is purchased, a unique lot number is created for it.
- Each production run produces a new stock lot of products.
- During production planning, MRPeasy automatically proposes which lot to pick materials from (FIFO or FEFO principle). The materials will be booked.
- No product or material can be overbooked, MRPeasy manages bookings.
- During production, workers see which materials they need to pick - the lot numbers, quantities, and location(s) - and can report materials they've used. (Section "My production plan")
- For each sale, specific stock lots from where products are booked and will be given out, are recorded.
- Defects in products can be traced back to specific production operations or material purchases in seconds. For a defective batch of materials, it is easy to identify all products which are affected.
- Expiry dates are recorded in stock lots.
- The actual cost of each lot of products is known (from direct materials cost, manufacturing and labor cost).
- If an item is subject to Quality Control then the stock lot will be quarantined until inspected and approved, or rejected, fully or partly.
- Service/repair orders can be scheduled for items that failed quality control or were returned by the customer.
- Individual serial numbers can be tracked within stock lots.
- Notes and files, e.g. certificates, can be attached to individual stock lots.
- To keep a lot number the same after transfer to another stock/production site, use a persistent custom field.
- Requested – required items are requested from:
- The purchasing manager, the purchase order status is New PO.
- The production manager, the manufacturing order status is New or Not scheduled.
Requested items cannot be consumed, picked for shipment.
- Planned – items are expected to arrive in some future. Purchase orders are ordered. Manufacturing orders are scheduled or started.
The software setting "Use planned goods" controls if planned items can be consumed and picked for shipment.
- Received – items are received.
- Canceled – the stock lot is deleted.
- On hold – items are received but wait for inspection. 5 and 6 available, if Quality Control is enabled.
- Rejected – items that did not pass inspection.
- RMA waiting for inspection – the RMA returned item is received and waiting for inspection. 7-10 available, if Return Merchandise Authorization (RMA) is enabled.
- RMA waiting for repair – the returned item is inspected and should be repaired.
- RMA ready for shipment – the returned item is repaired and can be shipped back to the customer.
- RMA returned – item is returned by the customer. It can be added to the inventory by changing the status to Received.
When the Enterprise function Packing is enabled, the column „Packaged“ can be added to the stock list view. This column shows how many items of those in this lot are packaged.
It is possible to print labels to identify physical items from different stock lots. The labels for stock lots can be printed by clicking Print label at
- the Stock -> Stock lots page,
- the Purchase Order, where the parts were procured.
- the Manufacturing order, where the products were manufactured.
The size, information, and layout of the label can be edited with the Label editor.
The standard label contains the unique stock lot barcode if the Barcode System functionality is enabled.
