# Transmission of data status for the monthly curtailed energy transfer time series (AAÜZ) between NB and BKV (anfNB) — ANB view The BIKO transmits the data status for the AAÜZ to the BKV (of the anfNB) and to the ANB. - after receipt of the AAÜZ from the NB or - after receipt of the validation notification from the BKV (anfNB) or - after use of the AAÜZ for the BKA (without KBKA) or the KBKA. ## Process flow from the perspective of the NB (ANB) \nSystem diagram: Übermittlung Datenstatus für die monatliche Ausfallarbeitsüberführungszeitreihe (AAÜZ) zwischen NB und BKV (anfNB) — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB (ANB)\n\nMarket partner\n\n\n\n2.

## Process information Wording of the consolidated version, profile ch. 17.3.5.5.1, pp. 280–281.
  1. ### Results All systems of BKV, ANB and BIKO hold the same data status for a version of the AAÜZ.
  2. ### Error case #### Result in the error case The BIKO informs all affected market participants and, after the error has been corrected, ensures that the correct data status is assigned to all affected AAÜZ. #### Error cases The algorithm applied by the BIKO for assigning the data status is faulty.
  3. ### First message **BIKO** sends “Data status for the monthly AAÜZ” (step 2). From here on, it is the turn of the party involved on this page.
  4. ### Objective The data status managed by the BIKO is available to the BKV (of the anfNB and of the ANB) for the AAÜZ.
## 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-datenstatus-fuer-die-monatliche-ausfallarbeitsueberfuehrungszeitreihe-aauez-zwischen-nb-und-bkv-anfnb) — BIKO - [View BKV-ANFNB](/en/prozessdoku/202610/BKV/MaBiS-uebermittlung-datenstatus-fuer-die-monatliche-ausfallarbeitsueberfuehrungszeitreihe-aauez-zwischen-nb-und-bkv-anfnb) — balance responsible party of the requesting grid operator · market role BKV *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 connector table lists no write call for these steps. Derived from the process flow: the process begins for the own role with their message, so the transaction is created.
