Let’s make sure you are getting the best out of your data!

Data quality is crucial for success in the automotive aftermarket. Only with flawless data vehicles and their respective spare parts can be determined unambiguously and without errors.

Competitiveness to OE identification systems

Significantly less effort in data maintenance

Higher trustworthiness & credibility

Boost your e-commerce business with high quality data

The success of online platforms directly depents on the quality of the product identification data and information available.

As online commerce continues to grow strongly, catalogue and ordering systems must offer high-quality product identification information.

Make decisions at your point of sale easier

The quality of the catalogue data determines whether the customer who relies on it to identify parts will be satisfied. Thus decision making and data quality are directly related.

For outstanding data quality in the TecDoc® Catalogue, information needs and information supply must ideally match. Better data supports the parts identification process leading to sustainable sales success.

Higher customer satisfaction at the point of sale

Save money through lower retail return rates

Stronger supplier-retailer business relationships

Premier Data Supplier (PDS)

Meets all our Certified Data Supplier criteria and other significantly more stringent content requirements. KPIs also encompass aspects of product content.

Certified Data Supplier (PDS)

Already meets specific requirements for TecDoc® data maintenance to a high degree. KPIs target basic TecDoc® guidelines.

The new “Gold Standard” in TecDoc® data quality

We are constantly working on improving the data quality in the TecDoc® catalogue. By introducing new requirements for our data suppliers in the form of validations and KPIs, we ensure that our TecDoc® data match the information needs at the point of service.

With the new “Premier Data Supplier” status, we honour the commitment of data suppliers whose data meet the high-quality standards in a special way and thus contribute to sustainable sales success. Because only through this cooperation in partnership can we increase confidence in the data basis of the TecDoc® catalogue.

The two statuses differ – apart from the different weighting – in that the underlying KPIs that must be fulfilled to achieve the respective award are aimed at two different levels.

The KPIs that must be fulfilled to achieve the new PDS status include, among others, the evaluation of data content such as free texts and attribute values (e.g. PR numbers, chassis numbers, equipment variants, etc.).

Our latest KPIs for data quality in the TecDoc® Catalogue

To ensure high data quality, we have established standardized production and update processes on the one hand and defined numerous guidelines for our data suppliers in the form of validations and KPIs on the other. In this way, we can ensure that the information needs at the PoS can be fully served by means of the data provided by our data suppliers.

Unlike the already known metrics for data quality, these are specifically aimed at product content. The KPIs you are already familiar with target the TecDoc® guidelines.


KPI 7 checks whether the supplied languages for text modules match the languages actually used (DE, EN, FR, IT, ES, NL, PL, RU, TR). It calculates what percentage of the text modules used are translated.


With KPI 7, we want to ensure that information is available at the PoS in the respective target languages (ISOCode_20) and can be understood accordingly by the customer.


Make sure that your translations in the text modules really correspond to the specified target language.


With KPI 8, we ensure that the links contain only allowed differentiation attributes.


With this evaluation criterion we can minimise the number of invalid differentiation attributes on the first catalog page.


Check the attributes for the first article page and make sure that only allowed differentiation attributes are used.


KPI 10 checks whether different article numbers linked to the same generic article for the same vehicle differ in at least one of the following parameters: Mandatory and/or differentiation attributes, article additional description, article status, use numbers, substitutions.


We collect this KPI so that the differentiation information of several products with the same name and different article numbers is directly visible on the first article page.


Check whether all links with the same generic article can be differentiated on the first article page. If this is not the case, use suitable differentiation attributes for this.


KPI 11 checks whether more than one decimal place is specified for certain attributes defined by TecDoc® per generic article. The specifications for these attributes are limited to a maximum of one single decimal place. Ideally, the value is entered without decimal places.


Keep it short and simple. With this KPI, we want to ensure that no more decimal places are displayed than absolutely necessary.


Check that the attributes from the list of generic items and attributes provided by us have max. one decimal place specified. Reduce this to max. one or at best none if this requirement is not yet met.


KPI 12 scans whether text modules contain information that can be transferred to attributes or to other areas of the TecDoc® data format.


With the introduction of this KPI, we want to ensure that the text modules contain only marketing text and no technical information or specifications (attributes). Search functions and OE2IAM mapping processes are not supported by free text information. Therefore, we provide any information that can be mapped as attributes as such. In contrast, free texts find their place in more suitable areas of the TecDoc® data format.


Check whether text modules contain information that can be better transported with standardised TecDoc® attributes or by means of other areas of the TecDoc® data format and transfer the information accordingly.


KPI 13 ensures that the values of alphanumeric attributes are directly related to the meaning of the respective attribute. They should only contain content that corresponds to the respective attribute in terms of content and structure.


With this KPI, we want to ensure that only really suitable values are assigned to alphanumeric attributes. Suitable in the sense that the respective assigned content is meaningfully related to the attribute.


Check the values of the alphanumeric attributes. Correct them if they do not exclusively contain values that correspond to the respective attribute in content and structure.


KPI 14 ensures ,that the numeric TecDoc® engine code attribute (14) is used instead of the alphanumeric attribute (33). The specified engine code is to be assigned to the target vehicle in the TecDoc® reference data on the basis of attribute 33.


We check this indicator to ensure that only the standardised TecDoc® engine code attribute is ever used to describe engine codes, instead of free text.


Please only use TecDoc® engine code as differentiation attribute if the desired engine code is already assigned to the target K- type/N-type in the TecDoc® reference data.
