+2. Schritt: Erkenne die Bereiche: Menüband oben, Visualisierungen rechts, Felder-Bereich rechts, Seiten-Navigation links.
+3. Schritt: Klicke auf eine leere Seite, damit Visualisierungen verfügbar werden.
+
+[Screenshot: Power BI Desktop mit markierter Berichtsansicht, Visualisierungen und Felder-Bereich].
+
+### 1.3 Excel-Datei importieren
+1. Schritt: Reiter → Start → Daten abrufen → Excel.
+2. Schritt: Datei auswählen → Öffnen.
+3. Schritt: Im Navigator Tabelle oder Blatt auswählen → Laden.
+
+Warnung: Wenn Du im Navigator mehrere Tabellen auswählst, kann die Ladezeit steigen.
+
+Häufige Probleme und Lösungen:
+1. Problem: Falsche Spaltennamen → Lösung: Erste Zeile als Header setzen (siehe Modul 2).
+2. Problem: Zahlen als Text → Lösung: Datentyp korrigieren (siehe Modul 2).
+
+### 1.4 CSV importieren
+1. Schritt: Reiter → Start → Daten abrufen → Text/CSV.
+2. Schritt: Datei auswählen → Öffnen.
+3. Schritt: Im Vorschaufenster Trennzeichen und Kodierung prüfen.
+
+Warnung: In der Schweiz sind Umlaute oft nur mit UTF-8 korrekt. Stelle Kodierung auf UTF-8, falls nötig.
+
+Hinweis: CSV hat keine Formeln oder Formatierungen – nur Rohdaten.
+
+### 1.5 SAP-Export importieren
+1. Schritt: SAP-Export (z. B. TXT/CSV/XLSX) in einen lokalen Ordner speichern.
+2. Schritt: Reiter → Start → Daten abrufen → Text/CSV oder Excel wählen.
+3. Schritt: Im Navigator prüfen, ob die erste Zeile die Spaltenüberschriften enthält.
+
+Tipp: Wenn die Überschriften fehlen, nutze Power Query → Erste Zeile als Überschriften.
+
+## 2. MODUL 2: POWER QUERY EDITOR
+
+### 2.1 Power Query öffnen
+1. Schritt: Reiter → Start → Daten transformieren.
+
+[Screenshot: Button 'Daten transformieren' im Menüband].
+
+### 2.2 Erste Zeile als Header verwenden
+1. Schritt: Reiter → Transformieren → Erste Zeile als Überschriften.
+2. Schritt: Prüfe, ob die Spaltennamen korrekt sind.
+
+### 2.3 Datentypen ändern
+1. Schritt: Spalte auswählen (z. B. Eintrittsdatum).
+2. Schritt: Reiter → Transformieren → Datentyp → Datum.
+3. Schritt: Bei Zahlen Datentyp → Dezimalzahl oder Ganze Zahl.
+
+Warnung: Schweizer Datumsformat (TT.MM.JJJJ) wird manchmal als Text erkannt. In diesem Fall zuerst Datentyp Text, dann Datum mit Gebietsschema Schweiz (Deutsch).
+
+### 2.4 Spalten entfernen/behalten
+1. Schritt: Unnötige Spalten markieren.
+2. Schritt: Reiter → Start → Spalten entfernen.
+
+Tipp: Nutze "Andere Spalten entfernen", um nur relevante Spalten zu behalten.
+
+### 2.5 Zeilen filtern
+1. Schritt: Filterpfeil in der Spalte Status.
+2. Schritt: Nur aktive Mitarbeitende auswählen.
+3. Schritt: Zeitraumfilter z. B. letztes Jahr.
+
+### 2.6 Werte ersetzen
+1. Schritt: Reiter → Transformieren → Werte ersetzen.
+2. Schritt: null durch 0 ersetzen.
+3. Schritt: Codes (z. B. 'A') durch Klartext (z. B. 'Aktiv') ersetzen.
+
+### 2.7 Spalten teilen/zusammenführen
+1. Schritt: Spalte auswählen.
+2. Schritt: Reiter → Transformieren → Spalte teilen (nach Trennzeichen).
+3. Schritt: Für Zusammenführen: Reiter → Transformieren → Spalten zusammenführen.
+
+### 2.8 Berechnete Spalte hinzufügen
+1. Schritt: Reiter → Spalte hinzufügen → Benutzerdefinierte Spalte.
+2. Schritt: Formel eingeben (z. B. Beschäftigungsgrad/100).
+
+### 2.9 Schliessen und Laden
+1. Schritt: Reiter → Start → Schliessen & laden.
+2. Schritt: Unterschied: "Laden" speichert in Modell, "Laden in" erlaubt gezielte Ziele (z. B. nur Verbindung).
+
+## 3. MODUL 3: DATENMODELL
+
+### 3.1 Zur Modellansicht wechseln
+1. Schritt: Links auf die Modellansicht (Beziehungs-Icon) klicken.
+
+### 3.2 Beziehungen verstehen
+1. Schritt: 1:n = Eine Zeile in Tabelle A passt zu vielen Zeilen in Tabelle B.
+2. Schritt: 1:1 = Jede Zeile passt genau zu einer anderen Zeile.
+
+Warum wichtig: Beziehungen steuern, wie Filter zwischen Tabellen fliessen.
+
+### 3.3 Beziehung erstellen
+1. Schritt: Spalte in Tabelle A auf passende Spalte in Tabelle B ziehen (Drag & Drop).
+2. Schritt: Beziehung prüfen → Kardinalität und Kreuzfilterrichtung einstellen.
+
+Tipp: Nutze meistens Einweg-Filterrichtung, um Mehrdeutigkeiten zu vermeiden.
+
+### 3.4 Datumstabelle erstellen
+1. Schritt: Reiter → Modellierung → Neue Tabelle.
+2. Schritt: DAX-Formel einfügen:
+
+```
+Datum = ADDCOLUMNS(CALENDAR(DATE(2020,1,1), TODAY()), "Jahr", YEAR([Date]), "Monat", MONTH([Date]), "MonatName", FORMAT([Date],"MMMM"), "Quartal", "Q" & QUARTER([Date]), "KW", WEEKNUM([Date]))
+```
+
+3. Schritt: Reiter → Tabellen-Tools → Als Datumstabelle markieren → Datum[Date] auswählen.
+
+### 3.5 PERNR als Schlüssel
+1. Schritt: Verwende die Personalnummer (PERNR) als Schlüssel zwischen allen SAP-Tabellen (PA0001, PA0002, PA0008, PA2001).
+
+## 4. MODUL 4: DAX MEASURES
+
+### 4.1 Was ist ein Measure vs. berechnete Spalte
+1. Schritt: Measure berechnet sich dynamisch im Berichtskontext.
+2. Schritt: Berechnete Spalte wird pro Zeile gespeichert und erhöht Modellgrösse.
+
+### 4.2 Neues Measure erstellen
+1. Schritt: Reiter → Modellierung → Neues Measure.
+2. Schritt: Formel eingeben und mit Enter bestätigen.
+
+### 4.3 Basis-Measures für HR
+```
+Headcount = COUNTROWS(Mitarbeiter)
+FTE = SUMX(Mitarbeiter, Mitarbeiter[Beschäftigungsgrad]/100)
+Krankheitstage = SUM(Abwesenheiten[Kalendertage])
+Sollarbeitstage = [Headcount] * 21
+Krankenquote = DIVIDE([Krankheitstage], [Sollarbeitstage], 0)
+Krankenquote_ohne_LZ =
+VAR KrankheitstageKurz = CALCULATE([Krankheitstage], FILTER(Abwesenheiten, Abwesenheiten[Kalendertage] <= 30))
+RETURN DIVIDE(KrankheitstageKurz, [Sollarbeitstage], 0)
+Austritte = CALCULATE(COUNTROWS(Mitarbeiter), Mitarbeiter[Austritt] <> BLANK())
+Avg_Headcount = AVERAGEX(VALUES(Datum[Monat]), [Headcount])
+Fluktuation = DIVIDE([Austritte], [Avg_Headcount], 0) * 100
+```
+
+### 4.4 Zeitintelligenz-Measures
+```
+Headcount_VJ = CALCULATE([Headcount], SAMEPERIODLASTYEAR(Datum[Date]))
+Headcount_VM = CALCULATE([Headcount], PREVIOUSMONTH(Datum[Date]))
+Headcount_YTD = TOTALYTD([Headcount], Datum[Date])
+Delta_VJ = [Headcount] - [Headcount_VJ]
+Delta_VJ_Proz = DIVIDE([Delta_VJ], [Headcount_VJ], 0)
+```
+
+### 4.5 Measures formatieren
+1. Schritt: Measure auswählen.
+2. Schritt: Reiter → Measure-Tools → Format → Prozent, Dezimalstellen, Währung einstellen.
+
+## 5. MODUL 5: VISUALISIERUNGEN

+
+### 5.5 Slicer erstellen
+1. Schritt: Visualisierung → Datenschnitt (Slicer) wählen.
+2. Schritt: Feld (z. B. Zeitraum, Abteilung) hinzufügen.
+
+### 5.6 Bedingte Formatierung
+1. Schritt: In Tabelle/Matrix auf Wertefeld klicken → Bedingte Formatierung.
+2. Schritt: Regeln definieren (z. B. Rot/Grün je nach Wert).
+
+Tipp: Ampel-Logik funktioniert gut für Krankenquote und Fluktuation.
+
+## 6. MODUL 6: DASHBOARD BAUEN
+
+### 6.1 Dashboard-Layout planen
+1. Schritt: F-Muster beachten – Wichtigstes oben links.
+2. Schritt: Maximal 6–8 Visualisierungen pro Seite.
+
+### 6.2 Seite 1: Management-Übersicht erstellen

+
+## 8. TROUBLESHOOTING
+
+### 8.1 Häufige Fehler beim Import
+1. Problem: Encoding-Probleme (UTF-8) → Lösung: Kodierung im CSV-Import anpassen.
+2. Problem: Dezimaltrennzeichen (Punkt vs Komma) → Lösung: Datentyp mit Gebietsschema Schweiz setzen.
+3. Problem: Datum als Text → Lösung: Datentyp Datum und richtiges Gebietsschema.
+
+### 8.2 Häufige DAX-Fehler
+1. Problem: Zirkelbezug → Lösung: Berechnete Spalten vermeiden, Measures nutzen.
+2. Problem: Division durch Null → Lösung: DIVIDE() verwenden.
+3. Problem: Falscher Filterkontext → Lösung: Filter mit CALCULATE prüfen.
+
+### 8.3 Beziehungsprobleme
+1. Problem: Mehrdeutige Beziehungen → Lösung: Eine Beziehung aktiv, andere inaktiv setzen.
+2. Problem: Fehlende Beziehung → Lösung: Schlüsselspalten prüfen (PERNR, Datum).
+
+### 8.4 Performance-Probleme

+      <h3>1) CDS View mit sauberem Datenmodell</h3>
+      <ul>
+        <li>Erstelle CDS Views je Fachthema (z. B. Personalstamm, Absenzen, Lohn).</li>
+        <li>PERNR als Schlüssel, Datum als ISO-Format (YYYY-MM-DD).</li>
+        <li>Sprache und Mandant berücksichtigen.</li>
+      </ul>
+
+      <h3>2) OData Service veröffentlichen</h3>
+      <ul>
+        <li>Expose CDS als OData (Fiori Elements oder Gateway).</li>
+        <li>Aktiviere in /IWFND/MAINT_SERVICE.</li>
+        <li>Setze Authentifizierung (SAML/OAuth/Basic nach IT-Policy).</li>
+      </ul>
+
+      <h3>3) Performance &amp; Paging</h3>
+      <ul>
+        <li>Paging aktivieren, Delta-Logik prüfen.</li>
+        <li>Nur benötigte Felder liefern (Thin Views).</li>
+        <li>Filter serverseitig ermöglichen (Datum, Mandant, Status).</li>
