What does 2BA offer?

Step 2: Trade Information

The second step is about the trade data of items. An item is an object that can be ordered by means of an item number (order number) or barcode. Trade data refers to the information relevant to the ordering and delivery process. With the trade records, the data supplier notifies its customers about such matters as the packaging forms in which their product is available. A product can have multiple packaging forms from one data provider [voorbeeld], where each item has its own item number and, if applicable, its own GTIN.

The technical data belongs to the product record (Step 3) to which the trade item refers. In addition to the manufacturer’s trade records, trade items from multiple wholesalers may be linked to one product [example]. The manufacturer is responsible for the presence of the product record and the accuracy of the product data in the Data Pool.

The reference to a product can be made in two ways;

  • based on (unique) GTIN/EAN
  • based on GLN + Product Code

Starting point is a 100% link between product and trade records.

The basic trade information of an item consists of:

1. Item Identification (order number / barcode (GTIN / EAN) and description)
2. Order Information (including minimum purchase, discount group)
3. Pricing Information (including gross price, conversion factor, price unit, price information with effective date in the future)
4. Logistics Information (including gross package dimensions and weight)
5. Item / Product Reference (GTIN and/or GLN + product code)
6. Commercial Information (deep link)

Consult the data requirements summary to gain insight into what data is expected by your customers for uniform data exchange

Global Trade Item Number (GTIN)

The GTIN (formerly EAN) is used for the globally uniform identification of trade units. Four GTIN numbering structures are available for trade item identification: GTIN-14, GTIN-13, GTIN-12 and GTIN-8. The GTIN is stored, aligned right and possibly supplemented with leading zeros in a 14-digit field. The choice of numbering structure depends on the goods and application of the user. The GTIN is a unique identifier and is issued and managed by the international organisation GS1.

If your organisation does not yet use GTIN numbers we strongly recommend that you start doing so. After all, the GTIN is the unique identifier of your product.

Packaging form hierarchy

If the product is available in different packaging forms - for example per metre, per roll of 100 metres or a reel of 500 metres - the advice is to communicate these packaging forms as standalone items through 2BA.

The smallest unit for pricing purposes:

  • If the item is orderable in this form, enter as orderable=yes
  • If the item is not orderable in this form, enter as orderable=no
  • Unit triangle according to GTIN (bleep)

We recommend that a separate GTIN be used for each packaging type, if no GTINs are available (yet) then a different item code with the addition of:

  • The number of use units of the packaging; or
  • The packaging code
Item Code Description Packaging Code Orderable
12345  Installation cable 1 metre (unpacked) no
12345_100 Installation cable 100 metre roll yes
12345_500 Installation cable 500 metre reel yes


Assortments are a collection of articles that fall within a certain group and have an umbrella name. For example, a supplier of electricity, sanitary and heating products can subdivide its range into specific groups. Assortments give users of selection profiles the option to select one or more sub-ranges instead of the entire range. Something that can make a significant difference in the amount of data to be received (and the processing thereof).

Price information with effective date in the future

In order to respond properly and promptly to changes in the market, wholesalers and installers want to have new price information available three months before the effective date. The Data Pool makes it possible to ‘prepare’ one or more price records per item (provided with a Price Effective Date) and make them available to the data consumers.

Real-time stock and net prices

If your organisation provides a stock and/or net price through a web service, or intends to develop it, then these web services can be linked to the Online Condition Server of 2BA. With this link, your customers have access to real-time stock and/or their (own) net price information (through authentication) of your items, for example in the 2BA Unifeed search engine or in their own ERP environment.

Possible options for the stock web service:

  • Stock available yes/no; this is indicated by a tick or cross.
  • The number in stock; this is indicated by the specific number in stock.
