# Transmission of the overview of the definitions of LF by LF — LF view The LF sends the - Overview of the metering time definitions of the LF, which contains all metering time definitions of the LF used by the LF, to all MSB or - Overview of the switching time definitions of the LF, which contains all switching time definitions of the LF used by the LF, to all NB and MSB or - Overview of the power curve definitions of the LF, which contains all power curve definitions of the LF used by the LF, to all NB and MSB. If the overview changes (e.g. in the overview of the metering time definitions of the LF, metering time definitions of the LF are added or metering time definitions of the LF are dropped), the updated overview is sent to all authorised parties. ## Process flow from the perspective of the LF \nSystem diagram: Übermittlung der Übersicht der Definitionen des LF durch den LF — view of LF\n\n\nCustomer backend system\n\nMACO APP · LF\n\nMarket partner\n\n\n\nProcess trigger received\n\n2 alternative events\n\nAPI\n\n1.

## Process information Wording of the consolidated version, profile ch. 1.2.2.1, pp. 9–10.
  1. ### Preconditions - The EDIFACT communication between LF and the authorized parties has been established. - The LF has - Metering time definitions of LF or - Switching time definitions of LF or - Power curve definitions of LF have been defined.
  2. ### Results The MSB or, where applicable, the NB can use the overview to assign the definition of the LF transmitted later by the LF to the MSB or, where applicable, to the NB via the use case “[Transmission of a definition of the LF by the LF](/en/prozessdoku/202610/LF/GPKE-Teil3-uebermittlung-einer-definition-des-lf-durch-den-lf)”.
  3. ### Further requirements If the LF uses a metering time period definition of the LF or a switching time definition of the LF or a power curve definition of the LF that cannot be transmitted within the use case „[Transmission of a definition of the LF by the LF](/en/prozessdoku/202610/LF/GPKE-Teil3-uebermittlung-einer-definition-des-lf-durch-den-lf)“, it is marked in the overview as „not electronically transmittable“.
  4. ### Trigger - The MSB does not have the current overview of the metering time definitions of the LF or - the NB or MSB does not have the current overview of the switching time definitions of the LF, or - the NB or MSB does not have the current overview of the power curve definitions of the LF. **Runs beforehand:** [Complaint about the overview of the definitions of the LF from MSB to LF](/en/prozessdoku/202610/LF/GPKE-Teil3-reklamation-der-uebersicht-der-definitionen-des-lf-vom-msb-an-lf), [Complaint about the overview of the definitions of the LF from NB to LF](/en/prozessdoku/202610/LF/GPKE-Teil3-reklamation-der-uebersicht-der-definitionen-des-lf-vom-nb-an-lf) — these processes name the one shown here in their result.
  5. ### First message The party involved on this page is itself the sender: “Overview of the definitions of the LF” to **NB** (step 1).
  6. ### Objective - The MSB have the current overview of the metering time definitions of LF available or - the NB and MSB have the current overview of the switching time definitions of the LF available or - the NB and MSB have the current overview of the power curve definitions of the LF available
## 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 NB](/en/prozessdoku/202610/NB/GPKE-Teil3-uebermittlung-der-uebersicht-der-definitionen-des-lf-durch-den-lf) — NB - [View MSB](/en/prozessdoku/202610/MSB/GPKE-Teil3-uebermittlung-der-uebersicht-der-definitionen-des-lf-durch-den-lf) — MSB *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.* These read accesses are not listed in the API catalogue of this format version; the step therefore shows only their command, without address and without button.
