The deployment of the EU Hub Release 1.16 scheduled for Q1 2025, will have no interface impact on the OBP side. Nevertheless, the EU Hub will still undergo modifications such that if OBPs upload a PMD and PPD without filling in the specified fields, the transaction will be rejected with an A16 validation error. With the deployment of the EU Hub Release 1.17 scheduled for Q2 2025, the EU Hub will undergo further modifications introducing a new OBP interface complementing the new mandatory fields. Consequently, if OBPs attempt to upload a PMD without filling in the indicated mandatory fields, the transaction will be rejected with a schema validation error (1*). Consequently, OBPs will need to update their interface connections to ensure the seamless continuation of their uploading transactions. Please contact your connection provider who will be able to assist you with this update. In case you are using the EMVO Gateway, please note that no actions are required from your side. In case you do not update your interface connection or fail to fill in properly the indicated mandatory fields, you will be unable to upload the data to the EU Hub.
