Overview
SIST EN 17015-2:2026 – Electronic Public Procurement - Catalogue - Part 2: Transactions is a European standard developed by the Slovenski inštitut za standardizacijo (SIST). This document specifies the transaction information requirements for electronic catalogues in public procurement. As part of broader interoperability efforts, it builds on the choreography frameworks outlined in EN 17015-1, focusing on the practical structuring, definition, usage, and validation of catalogue-related transactions exchanged between public sector buyers and suppliers.
This standard outlines the necessary terms, business requirements, and information models for key procurement transactions, supporting efficient, transparent, and standardized e-procurement processes across European public administration and regulated sectors.
Key Topics
SIST EN 17015-2:2026 covers five principal procurement transactions:
- Catalogue: The creation and transmission of structured lists of products or services by providers to buyers for purchasing purposes.
- Catalogue Response: Communications from catalogue receivers confirming acceptance, rejection, or requiring revisions of submitted catalogues.
- Pre-award Catalogue Request: Requests issued in the pre-award phase of tenders for suppliers to provide catalogued offers based on specific requirements.
- Pre-award Catalogue: Catalogue submissions provided as part of the vendor’s tender response, ensuring bid alignment with buyer requirements.
- Shopping Cart: The selection and grouping of catalogue items for purchase, often leading to the formation of an order.
The standard details:
- Business requirements for each transaction, ensuring clarity, accuracy, and data integrity.
- Models including definitions of required data elements, their usage, and cardinality.
- Guidance for compliance and conformance claims, with explicit instructions on fulfilling business rules and data inclusion/exclusion.
Common requirements include:
- Consistent currency and positive amounts for all transactions.
- Complete transaction identity and organizational information.
- Avoidance of dependencies on external data repositories.
Applications
This standard is relevant to a range of actors in public procurement and digital supply chains, including:
- Public sector organizations implementing e-procurement platforms to increase efficiency and transparency.
- Solution and software providers building or integrating catalogue management modules for e-procurement, tendering, and contract management systems.
- Suppliers and vendors participating in public procurement processes, ensuring their catalogue data is compliant for automated processing and evaluation.
- Consultancies and service integrators supporting digital transformation in government procurement or large infrastructure projects.
Practical benefits:
- Reduces manual intervention and errors by standardizing procurement data.
- Enables automated validation and approval processes.
- Improves interoperability among e-procurement platforms at regional, national, and European levels.
- Meets regulatory and legal obligations for electronic purchases and tender responses.
