Buenos días,

Estoy haciendo un Power BI que muestra el avance de la resolución de errores que tienen varias personas. Estos errores los actualizo mes a mes. Lo que quiero es que, si los errores aumentan un porcentaje con respecto al mes anterior, aparezca.

Es decir: Si la suma de los errores del mes actual, es un 10 % mayor a la suma de errores del mes pasado, que aparezca el nombre del responsable.

Saludos y muchas gracias

Hi again,

You can delete these steps:

but in CombinedTables step, you should specify your tables.

Whole code with sample data:

``````let
fnShift = (tbl as table, col as text, shift as nullable number, optional newColName as text, optional _type as type) as table =>
//v 3. parametri zadaj zaporne cislo ak chces posunut riadky hore, kladne ak dole, 4. je nepovinny (novy nazov stlpca), 5. je nepovinny typ
let
a = Table.Column(tbl, col),
b = if shift = 0 or shift = null then a else if shift > 0
then List.Repeat({null}, shift) & List.RemoveLastN(a, shift)
else List.RemoveFirstN(a, shift * -1) & List.Repeat({null}, shift * -1),
c = Table.FromColumns(Table.ToColumns(tbl) & {b}, Table.ColumnNames(tbl) &
( if newColName <> null then {newColName} else
if shift = 0 then {col & "_Duplicate"} else
if shift > 0 then {col & "_PrevValue"}
else              {col & "_NextValue"} )),
d = Table.TransformColumnTypes(c, {List.Last(Table.ColumnNames(c)), if _type <> null then _type else type any})
in
d,

TableFebruary = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8ipNzFPSUTICYkMobWCob2Ckb2RgZKIUqxOt5JiTlFpUkg9VYACjURV55RenIsmiq4gFAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Nombre = _t, Pinchazos = _t, Motor = _t, Chapa = _t, Fecha = _t]),

Buenos días,

Tabla de Febrero

 Nombre Pinchazos Motor Chapa Fecha Juan 2 1 2 01/02/2024 Alberto 1 0 1 01/02/2024 Jose 0 1 1 01/02/2024

Tabla de Marzo

 Nombre Pinchazos Motor Chapa Fecha Juan 1 0 2 01/03/2024 Alberto 1 1 4 01/03/2024 Jose 1 0 1 01/03/2024

Quiero sumar todos los errores de Juan, Alberto y Jose y comprobar si el mes siguiente ha aumentado un 10% los errores.

Por ejemplo: Cogemos a Juan, que la suma de los errores de Febrero es 5 (2+1+2), le suamos un 10% y la comparamos con la suma de errores de Marzo que es 3 (1+0+2). Es decir, 5X10/100=0,5--5+0,5=5,5>3. En este caso Juan no aparecería porque en Marzo ha bajado los errores.

Por otro lado, Alberto=Errores Febrero+10% es menor que Errores Marzo--1+0+1=2+2x10/100=2,2<(1+1+4)=2,2<6. Por lo que Alberto si debería aparecer.

Y con el caso de Jose=Errores Febrero+10%<Errores Marzo--(0+1+1)+2x10/100<1+0+1=2+0,2<2=2,2<2. Por lo que Jose no debería aparecer
