Work with Barcode Nomenclature
|
||
==============================
|
||
|
||
There are different situations in which barcode nomenclatures can be
|
||
useful. A well-known use case is the one of a point of sales that sells
|
||
products in bulk. The customers will scale their products themselves and
|
||
get the printed barcode to stick on the product. This barcode will
|
||
contain the weight of the product and help compute the price
|
||
accordingly.
|
||
|
||
Create a Barcode Nomenclature
|
||
=============================
|
||
|
||
Odoo supports *Barcode Nomenclatures*, which determine the mapping and
|
||
interpretation of the encoded information.
|
||
|
||
To configure the *Barcode Nomenclature*, you need to activate the
|
||
debug mode. To do so, go to *Inventory > Configuration > Barcode
|
||
Nomenclature*.
|
||
|
||
You can create a barcode nomenclature from there, and then add a line to
|
||
create your first rule.
|
||

||

||

|
||
|
||
The first step is to specify the *rule name*, for example *Weight
|
||
Barcode* with 3 decimals. Then, you have to specify the type for
|
||
barcode nomenclature, like the *Weighted Product*.
|
||

|
||
|
||
The *Barcode Pattern* is a regular expression that defines the
|
||
structure of the barcode. In this example, 21 defines the products on
|
||
which the rule will be applied. Those are the numbers by which the
|
||
product barcode should start. The 5 “dots” are the following numbers of
|
||
the product barcode and are there to identify the product in question.
|
||
The “N” defines a number and the “D” defines the decimals.
|
||
|
||
.. note::
|
||
You can define different rules and order their priority thanks to the
|
||
sequence. The first rule that matches the scanned barcode will then be
|
||
applied.
|
||
|
||
Configure your Product
|
||
======================
|
||
|
||
1. The barcode of the product should start by “21”;
|
||
|
||
2. The 5 “dots” are the other numbers of your product barcode, allowing to identify the product;
|
||
|
||
3. The barcode should contain 0’s when you did defined D’s or N’s. In our case, we need to set 5 zeros because we condigures “21………{NNDDD}”;
|
||
|
||
4. In EAN-13, the last number is a check number.

In case you weight 1,5kg of pasta, the balance will print you the
|
||
following barcode: *2112345015001*. If you scan this barcode in your
|
||
PoS, or when receiving the products in your barcode app, Odoo will
|
||
automatically create a new line for the product, for a quantity of
|
||
1,5kg.
|
||
|
||
For the point of sale, a price depending on the quantity will also be
|
||
computed.

Rule Types
|
||
==========
|
||
|
||
- **Priced Product**: it allows you to identify the product and specify its price, used in PoS;
|
||
|
||
- **Discounted Product**: it allows you to create one barcode per applied discount. Then, you can scan your product in the PoS and apply discounts on the product by scanning the discount barcode;
|
||
|
||
- **Weighted Product**: it allows you to identify the product and specify its weight, used in both PoS and in Inventory;
|
||
|
||
- **Client**: it allows you to identify the customer, for example used with loyalty program;
|
||
|
||
- **Cashier**: it allows you to identify the cashier when entering the PoS;
|
||
|
||
- **Location**: it allows you to identify the location on a transfer when multi-location is activated;
|
||
|
||
- **Package**: it allows you to identify packages on a transfer when packages are activated;
|
||
|
||
- **Lot**: it allows you to identify the lot number of a product on a transfer;
|
||
|
||
- **Credit Card**: it doesn’t need manual modification, exists for data from the Mercury module;
|
||
|
||
- **Unit Product**: it allows you to identify a product for both PoS and Transfers.
|
||
|
||
.. note::
|
||
When the barcode pattern contains .*, it means that it can contain any
|
||
number of characters. Those characters can be any number.
