Dos monedas

Manual paso a paso

Las capturas muestran Q-Expert en inglés; la interfaz en español llegará pronto.

01La pregunta de negocio

Q-Expert Distributors vende en pesos y en dólares. Cada venta debe valorarse en pesos con la tasa de cambio vigente en su propia fecha y ubicarse en una banda de monto. En el camino, los errores de captura y los productos descontinuados deben salir del análisis.

02Antes de empezar

03Paso a paso

  1. 1

    Limpia las ventas

    Agrega un TXF tmp_Sales después de tmp_SalesRaw. En Expressions:

    • Date(Date#(SaleDate, 'YYYY-MM-DD')) como SaleDate
    • ApplyMap('map_CustomerSurvivor', CustomerID, -1) como CustomerID
    • ApplyMap('map_ChannelName', Channel, 'Other') como ChannelName
    • Quantity * UnitPrice * (1 - DiscountPct / 100) como NetAmount

    Activa WHERE con Quantity > 0. Luego un DROP de tmp_SalesRaw.

    Limpia las ventas
    Figura 4.1 — Limpia las ventas
  2. 2

    Conserva solo productos activos

    Agrega un nodo JOIN, operación INNER JOIN, entre Product (solo su ProductID) y tmp_Sales. Las ventas de productos descontinuados salen del análisis.

    Conserva solo productos activos
    Figura 4.2 — Conserva solo productos activos
  3. 3

    Encuentra la tasa vigente de cada venta

    Carga ExchangeRates.csv como tmp_ExchangeRate, con Date#(…, 'YYYY-MM-DD') en ValidFromDate y ValidToDate. Luego agrega un INTERVALMATCH tmp_RateBridge:

    • Campo de coincidencia SaleDate
    • Inicio ValidFromDate, fin ValidToDate
    • Llave adicional Currency
    Encuentra la tasa vigente de cada venta
    Figura 4.3 — Encuentra la tasa vigente de cada venta
  4. 4

    Lleva la tasa a las ventas

    Tres nodos y una limpieza:

    • Un TXF tmp_SaleRate (NoConcatenate) lee el puente.
    • Un LEFT JOIN le agrega Rate desde tmp_ExchangeRate.
    • Un segundo LEFT JOIN lleva SaleDate, Currency, Rate a tmp_Sales, con el WHERE Currency <> '$(vBaseCurrency)'.
    • Un DROP de las tres tablas de trabajo.
    Lleva la tasa a las ventas
    Figura 4.4 — Lleva la tasa a las ventas
  5. 5

    Valora cada venta en pesos

    Un TXF Sales (NoConcatenate) lee tmp_Sales y agrega Round(NetAmount * Alt(Rate, 1)) como NetAmountCOP. Luego un DROP de tmp_Sales.

    Valora cada venta en pesos
    Figura 4.5 — Valora cada venta en pesos
  6. 6

    Ubica cada venta en una banda de monto

    El mismo patrón otra vez:

    • tmp_AmountBand desde AmountBands.csv.
    • Un INTERVALMATCH tmp_BandBridge sobre NetAmountCOP entre FromAmount y ToAmount.
    • Un puente tmp_SaleBand con la banda unida.
    • Un LEFT JOIN de AmountBand en Sales.
    • Un DROP de las tablas de trabajo y del campo SourceFile.
    Ubica cada venta en una banda de monto
    Figura 4.6 — Ubica cada venta en una banda de monto
  7. 7

    Guarda las ventas y luego detente a mirar

    Dos checkpoints después de Sales:

    • STORE a $(vTxfPath)Sales.qvd: la tabla de ventas de la capa Transform.
    • Uno de depuración que guarda $(vTxfPath)Sales_Check.qvd con Exit Script marcado, así la recarga se detiene mientras revisas las ventas.
    Guarda las ventas y luego detente a mirar
    Figura 4.7 — Guarda las ventas y luego detente a mirar
  8. 8

    Genera el script

    Generate Syntax. Las tablas de mapeo se cargan primero; la última pestaña termina con las tablas de trabajo eliminadas, DROP FIELD SourceFile, STORE [Sales] INTO …Sales.qvd y el STORE + EXIT SCRIPT de depuración.

    Genera el script
    Figura 4.8 — Genera el script

04Revisa tu resultado

_Main

Se pega en Qlik

Este es el único script que pegas en Qlik Sense: abre el Editor de carga de datos de la app, reemplaza su contenido por este y recarga. Cada línea $(MUST_INCLUDE=…) lee en su lugar uno de los archivos de abajo, así el resto del modelo nunca entra al editor.
