Descuadre de errores

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

You can delete these steps:

dufoq3_1-1712136163298.png

 

but in CombinedTables step, you should specify your tables.

dufoq3_2-1712136309175.png

 

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]),

    CombinedTables = Table.Combine({ ChangedTypeFeb, ChangedTypeMarch }),
    UnpivotedOtherColumns = Table.UnpivotOtherColumns(CombinedTables, {"Nombre", "Fecha"}, "Error Type", "Value"),
    ChangedFechaFormat = Table.TransformColumns(UnpivotedOtherColumns, {{"Fecha", each Date.ToText(_, "yyyy-MM", "es-ES"), type text}}),
    GroupedRows = Table.Group(ChangedFechaFormat, {"Nombre"}, {{"All", each 
        [ a = Table.Group(Table.Sort(_, {{"Fecha", Order.Ascending}}), {"Fecha"}, {{"Errors", each List.Sum([Value]), Int64.Type}}), //Sort + inner group
          b = fnShift(a, "Errors", 1, null, Int64.Type), //shift rows - add prev. value

Buenos días,

 

Añado algunos datos de muestra:

Tabla de Febrero

NombrePinchazosMotorChapaFecha
Juan21201/02/2024
Alberto10101/02/2024
Jose01101/02/2024

 

Tabla de Marzo

NombrePinchazosMotorChapaFecha
Juan10201/03/2024
Alberto11401/03/2024
Jose10101/03/2024

 

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

 

Saludos y gracias
