Pregunta de modelado de datos

Hola comunidad.

Por favor, solicito ayuda con una duda sobre modelado de datos.

 

Cuando relaciono mi base de datos (Tabincidentes) con la tabla creada (Tab_Periodo), veo que en esta última la selección se extiende una fila más, generando opción En Blanco al momento de utilizarla como filtro en el informe:

Sin embargo, al momento de crear la tabla, esta no tiene filas sobrantes:

Espero se haya podido entender. Muchas gracias de antemano a quien me pueda ayudar a comprender qué pasa acá y cómo podría solucionarse.

Hi  @nrivera ,

I created some data:

As far as I know, when you join two tables in a relationship and there is extra data in the Tablncidentes table that doesn't exist in the Tab_Periodo table then there will be blank value  in the slicer, you can use the visual level filter to filter the data for products that aren't blank.

Hi @nrivera - Revise las fechas de su período en Tab_Periodo y asegúrese de que no haya espacios ni superposiciones.
Limpieza de datos: asegúrese de que no haya valores nulos en sus columnas clave (como Hora_creacion y Inicio/Fin). Si es necesario, agregue un valor predeterminado para manejar valores nulos.
Verificación de datos adicionales: utilice columnas o medidas calculadas para resaltar o filtrar registros que no tengan períodos de fechas coincidentes.
Si estas sugerencias no resuelven el problema, también puede considerar crear una medida que excluya los valores en blanco al filtrar o usar Power Query para depurar y comprobar si hay filas faltantes o adicionales que podrían estar contribuyendo al problema del filtro en blanco.
