The second step is all about the sales data of articles. An article is a description of an object that can be ordered using the article number (order number) or bar code. Commercial data refer to the information that is relevant for the ordering and provision process.

The technical data are stored with the product (Step 3) to which the article is linked. Several articles of several suppliers may be linked to a single product. The manufacturer is responsible for the presence and accuracy of the product data and the linked article used to inform his consumers.

The reference to the product may be produced in one of two ways:

- based on a (unique) GTIN/EAN

- based on a GLN + product code

The point of departure of InstallData is that there must be a 100% link between product and sales records.


The basic information for an article consists of:

1. Article identification

(order number / bar code (GTIN / EAN) and description)

2. Order information

(including minimum consumption, discount group)

3. Price information

(including gross price, conversion factor, price unit, price information with a start date in the future)

4. Logistics information

(including gross packaging dimensions and weight)

5. Article/product reference

(GTIN and/or GLN + product code)

6. Commercial information



Price information with a start date in the future

In order to anticipate changes in the market, wholesalers and installers want to have new price information available two months before the start date. InstallData provides the option of 'preparing# one or several price records per article and to make them available to data consumers.

Global Trade Item Number (GTIN)

The GTIN (formerly EAN) is used for the worldwide, unique identification of sales units. Four GTIN numbering structures are available for the identification of sales units: GTIN-14, GTIN-13, GTIN-12 and GTIN-8. The GTIN is saved and right-aligned, possibly preceded by zero digits in a field comprising 14 digits. The choice of numbering structure depends on the goods and the application of the user. The GTIN is a unique number and is issued and managed by the international organisation GS1.

If you organisation does not yet have GTIN numbers, we strongly advise you to consider this. After all, the GTIN is the unique identification for your product.
