Dynamic filtering a column containing several keywords

[stchln]

Hello,

I think I need your help on a filtering I would like to do.

I have a table TP, simplified, as below. It contains a column P with some references and a column L containing a list of tags. Why I would like to do is to create a dynamic filter table in which I could just click on one of the tags that would filter the list of references in table TP

My first step : to be able to create a table of tags that I could use as filter

TP is the initial table 

P	L
P1	AA,BB
P2	BB
P3

After creating a 1st table, named TPS, split of table TP by column L with option by Rows I get a table as below

P	L
P1	AA
P1	BB
P2	BB
P3

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCjBU0lFydNRxclKK1QFyjYBcGNsYyFaKjQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [P = _t, L = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"P", type text}, {"L", type text}}),
    #"Split Column by Delimiter" = Table.ExpandListColumn(Table.TransformColumns(#"Changed Type", {{"L", Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv), let itemType = (type nullable text) meta [Serialized.Text = true] in type {itemType}}}), "L"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"L", type text}})
in
    #"Changed Type1"

Then, from TPS, I build a 3rd table of possible tags, named TF just by removing other columns as explained in post (LINK)

F

AA

BB

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCjBU0lFydNRxclKK1QFyjYBcGNsYyFaKjQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [P = _t, L = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"P", type text}, {"L", type text}}),
    #"Split Column by Delimiter" = Table.ExpandListColumn(Table.TransformColumns(#"Changed Type", {{"L", Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv), let itemType = (type nullable text) meta [Serialized.Text = true] in type {itemType}}}), "L"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"L", type text}}),
    #"Removed Columns" = Table.RemoveColumns(#"Changed Type1",{"P"})
in
    #"Removed Columns"

Then, I create a model with relationships between TP.P and TPS.P (n to 1) using L column as Key and a second relationship between TPS.L and TF.F (n to 1) using L/F as a key

At this point, if I create a display with the three tables in same page, when I click on a row of table TF this is filtering correctly in table TPS (where I have the split) but nothing happens for the initial table TP. Somethink like there is no transitivity...

--> This is second problem I am trying to solve... with your help

Tables with filtering

If I select in table TF row containing AA, selecting correctly applies on table TPS but nothing happens on table TP...

Thanks for your help!

Get rid of table TP from the finished model - it's redundant.

If you want a table visual that represents a filtered table TP then build it from TPS (probably using CONCATENATEX in a measure to build the string)

Hi

I found a solution on

- remove all relationships

- create a measure attached to TP

Measure = SEARCH(
    SELECTEDVALUE(TF[L]),
    SELECTEDVALUE(TP[L]),
    ,-1
)

- Add a slicer with Measure greater than or equal to 1
