# Transmission of the supplier curtailed energy aggregated time series — ANB view For the balancing month, the NB delivers the LF-AASZR to the LF for every activated MaBiS-ZP. The LF checks the LF-AASZR and can, where required, communicate the check result to the NB by means of the validation notification. The curtailed energy per TR is aggregated per market location and totalled per balancing group across all market locations of the respective supplier. ## Process flow from the perspective of the NB (ANB) \nSystem diagram: Übermittlung der Lieferantenausfallarbeitssummenzeitreihe — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB (ANB)\n\nMarket partner\n\n\n\n1.

## Process information Wording of the consolidated version, profile ch. 17.3.2.4.1, p. 241.
  1. ### Preconditions The NB has activated the ZP for the LF-AASZR for the time period under consideration.
  2. ### First message The party involved on this page is itself the sender of: „LF-AASZR“ to **LF** (step 1).
  3. ### Objective The LF has the LF-AASZR from the NB. In addition, the NB may have a check result from the LF on the LF-AASZR by means of a validation notification.
## 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 LF](/en/prozessdoku/202604/LF/MaBiS-uebermittlung-der-lieferantenausfallarbeitssummenzeitreihe) — LF *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) 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: [2](#schritt-2) 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. Applies to: [1](#schritt-1), [2](#schritt-2)
