How do I filter for the concentrate of all set filters in PowerBI? - powerbi-desktop

Question

I have data in this form:
In PowerBI, I added another column where I keep only code combinations that consist of one single code. I did this with something like IF(LEN(Code > 1), "", Code). Result:
This enables me to create a slicer that contains only single codes. I also added a table that shows Codes.
Now, when I select codes in the slicer, I want the table to show these codes, plus the exact combination of it.
For example, when I select A and B, the table should show me A and B and A, B. I don't want it to show A, B, C although it contains A and B.
If I filter for A and B and C, however, I want it to show A and B and C and A, B, C - but not A, B.
How can I achieve that?
All entries in Codes are saved as strings.

You need a disconnected (not connected to the base table) table for your slicer. Now, if I consider your base table name is - your_table_name, you can create the new slicer table with this below code-
slicer =
SELECTCOLUMNS(
FILTER(
your_table_name_8,
LEN(your_table_name_8[codes]) = 1
),
"code",your_table_name_8[codes]
)
After creating the new slicer table, check in the model is there any auto relation detected between 2 tables or not. If you find any relation, just Remove the relation.
Now, create your slicer from the newly created table and create this below measure in your base table your_table_name-
show_or_hide =
VAR current_code = MIN(your_table_name_8[codes])
VAR comma_separated_list =
CALCULATE (
CONCATENATEX (
VALUES(slicer[code]),
slicer[code],
","
)
)
RETURN
IF(
current_code = comma_separated_list || (LEN(current_code) = 1 && CONTAINSSTRING(comma_separated_list,current_code)),
1,
0
)
lets see the outcome-
Finally, you can apply a visual level filter using the new measure show_or_hide and apply a filter so that value with True only shown in the visual.
Reorder Combination
Let we have this following table-
Now this following code from Advanced Query Editor will give the the expected output-
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WctRx0nFWitUBsZx1nJRiYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
#"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 1, 1, Int64.Type),
#"Reordered Columns" = Table.ReorderColumns(#"Added Index",{"Index", "Column1"}),
#"Split Column by Delimiter" = Table.SplitColumn(#"Reordered Columns", "Column1", Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv), {"Column1.1", "Column1.2", "Column1.3"}),
#"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Column1.1", type text}, {"Column1.2", type text}, {"Column1.3", type text}}),
#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type1", {"Index"}, "Attribute", "Value"),
#"Added Custom" = Table.AddColumn(#"Unpivoted Other Columns", "column_name", each "Column-" & [Value]),
#"Changed Type2" = Table.TransformColumnTypes(#"Added Custom",{{"column_name", type text}}),
#"Removed Columns" = Table.RemoveColumns(#"Changed Type2",{"Attribute"}),
#"Reordered Columns1" = Table.ReorderColumns(#"Removed Columns",{"Index", "column_name", "Value"}),
#"Sorted Rows" = Table.Sort(#"Reordered Columns1",{{"Index", Order.Ascending}, {"column_name", Order.Ascending}}),
#"Pivoted Column" = Table.Pivot(#"Sorted Rows", List.Distinct(#"Sorted Rows"[column_name]), "column_name", "Value", List.Min),
#"Merged Columns" = Table.CombineColumns(#"Pivoted Column",{"Column-A", "Column-B", "Column-C"},Combiner.CombineTextByDelimiter(",", QuoteStyle.None),"Merged")
in
#"Merged Columns"
Please check what applied in steps one by one for better understanding. Here is the output with ascending order in the combination-
Index column added for keep tracking the row from start to end. If you have already a similar column, you can use that column as well.
