System diagram: Übermittlung Prüfmitteilung des Deltazeitreihenübertrags von NB über BIKO an ÜNB

# Transmission of validation notification for the delta time series carry-over from NB via BIKO to ÜNB — NB view The DZÜ forwarded by the BIKO is available at the NB. The NB plausibility-checks the DZÜ against the DZÜ list and transmits a validation notification to the BIKO. The BIKO forwards it to the ÜNB, provided it is not rejected. If the NB sends a negative validation notification for a DZÜ, it is obliged to send the ÜNB a DZÜ correction list. This response message is made electronically in standardised form. Further steps towards clarification are taken via other communication channels. ## Process flow from the perspective of the NB \nSystem diagram: Übermittlung Prüfmitteilung des Deltazeitreihenübertrags von NB über BIKO an ÜNB — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB\n\nMarket partner\n\n\n\n1.

## Process information Wording of the consolidated version, profile ch. 12.6.1, pp. 174–175.

### Preconditions - The ÜNB has formed the DZÜ and transmitted it successfully to the BIKO. The BIKO has forwarded the DZÜ along the chain to the NB.
### Results - If the validation notification is positive, the BIKO can form the data status and transmit it to the NB and ÜNB.
### First message The party involved on this page is itself the sender of: „Validation notification DZÜ“ to **BIKO** (step 1).
### Objective - The NB has checked the DZÜ against its data and has transmitted its check result to the BIKO. - The BIKO has forwarded this to the ÜNB. - The ÜNB knows the expectation (need for correction or acceptance) of the NB for the DZÜ of the time period under consideration. - If NB has sent a negative validation notification for DZÜ, the response message for the DZÜ list is available to ÜNB.

## Other views of the process The same process through the eyes of the other parties involved: the same steps, each read from their point of view. - [View BIKO](/en/prozessdoku/202610/BIKO/MaBiS-uebermittlung-pruefmitteilung-des-deltazeitreihenuebertrags-von-nb-ueber-biko-an-uenb) — BIKO - [View ÜNB](/en/prozessdoku/202610/UENB/MaBiS-uebermittlung-pruefmitteilung-des-deltazeitreihenuebertrags-von-nb-ueber-biko-an-uenb) — ÜNB · market role UENB *The steps are the **possible** messages of this process, not a sequence — the source lists neither conditions nor alternatives. The small box on the step names the own view on the left: with **←** it receives, with **→** it sends. Collapsed steps run between other market partners.* The source does not yet name the event that triggers these steps. Applies to: [1](#schritt-1), [2](#schritt-2) The connector table lists no write call for these steps. Derived from the process flow: the own role was already involved in this process, so the transaction already exists. Applies to: [3](#schritt-3) For the check identifiers of these steps there is no test case in the test data set; the »Try it out« button of the write interface therefore offers no body.
