Hi,
I'm looking forward to sorting my employee column in a certain order.
Here is the list of employees that I want to be sorted into a group.
Group 1 is all the numeric ones.
G2 alphanumeric with one character(C to Z) and numbers.
Lastly, two-character and rest numeric.
Please let me know if it's possible or no?
Thank you for helping.

Hi @Anonymous - this is certianly possible. Here is one way. This simply goes through the data converting the employee "number" (I put that in quotes as your employee numbers are text, which is usually the best way to handle it) to a numberic value and if it works, it classifies it as "Numberic." If it fails, it removes the first character and tries again. If it works, it is 1 char, otherwise, it tries again removing the first two characters. It doesn't classifiy anything starting with A or B. Leaves those null. You can change that in the M code below.
The full M code of my example is here.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQyVorViVYyMTUD0+YWlmA6GShhAmEZw+SSk2Gqk5NhYknlYFYsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Employee Number" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Employee Number", type text}}),
#"Added Grouping" =
Table.AddColumn(
#"Changed Type",
"Grouping", each
if List.Contains({"a".."b"}, Text.Start([Employee Number], 1)) then null
else if (try Number.FromText([Employee Number]))[HasError] = false then "Numeric"
else if (try Number.FromText(
Text.End([Employee Number], Text.Length([Employee Number]) -1)
)
)[HasError] = false then "One Letter"
else if (try Number.FromText(
Text.End([Employee Number], Text.Length([Employee Number]) -2)
)
)[HasError] = false then "Two Letters" else null
)
in
#"Added Grouping"

MCSA: BI Reportingmy previous post refer to somethink that seem to give answer to that request.
look the picture sequence and tell me where you would somethink different (naming aside).
I use the table.partition function with the help of a function built for the occasion that "classifies" text strings.
I believe that the technique can be of general validity and also apply to other situations in which rows of tables must be grouped on the basis of "complex" criteria
here the function typedStr
let
tipizza=(str,optional firstN,optional lastN)=>
let
lst= if firstN<> null and lastN<>null then Text.ToList(Text.End(Text.Start(str,firstN),lastN)) else
if firstN<> null and lastN=null then Text.ToList(Text.Start(str,firstN)) else
if firstN= null and lastN<>null then Text.ToList(Text.End(str,lastN)) else
Text.ToList(str),
tpz=List.Transform(lst, each if List.Contains({"a".."z"}, _) then "char" else if List.Contains({"0".."9"}, _) then "digit" else null)
in
tpz
in tipizza
here the rest of code
let
hash={{"digit","digit"},{"char","digit"},{"char","char"}},
part=Table.Partition(
Table.FromRecords({
[a = "9020", b = 4],
[a = "9021", b = 4],
[a = "9494", b = 4],
[a = "c1494", b = 4],
[a = "c38696", b = 4],
[a = "c3855", b = 4],
[a = "z3467", b = 4],
[a = "ca38", b = 4],
[a = "zz386", b = 4],
[a = "vc386", b = 4],
[a = "ff179844", b = 4]
}),
"a",
3,
each List.PositionOf(hash,typedStr(_,2))
),
tab=Table.FromList(part,Splitter.SplitByNothing(),null,null),
#"Added Index" = Table.AddIndexColumn(tab, "Index", 0, 1),
#"Added Custom" = Table.AddColumn(#"Added Index", "Custom", each hash{[Index]}),
#"Extracted Values" = Table.TransformColumns(#"Added Custom", {"Custom", each Text.Combine(List.Transform(_, Text.From), ":"), type text}),
#"Removed Columns" = Table.RemoveColumns(#"Extracted Values",{"Index"}),
#"Expanded Column1" = Table.ExpandTableColumn(#"Removed Columns", "Column1", {"a"}, {"Column1.a"})
in
#"Expanded Column1"
which starting from:
gives the following result
@Anonymousanother solution without using lists, by using Text.Length, Text.Select and the sketchy text comparisons.
#"Added Employee Group" =
Table.AddColumn(
Source,
"Employee Group",
each
let
CorrectTextFormat = Text.Upper(Text.From([Employee Number])),
Result =
Text.Length(Text.Select(CorrectTextFormat, {"A".."Z"}))
+ 1,
CheckIfInGroup = (CorrectTextFormat >= "C" or CorrectTextFormat <= "9") and Result < 4
in
if CheckIfInGroup then
"G" & Text.From(Result)
else
null
)
Best,

MCSA: BI ReportingThank you for the post and appreciate your helping but, it doesn't meet the requirements.
We have a column that has multiple values such as numeric and alphanumeric. We want to create a new column where we can select the filter options that will result in just numbers, starting A character or first two characters sorting functionality.
Please let me know if that is possible.
Thank you
I don't understand if your original problem is solved or not.
Could you give some input table and expected results, possibly in a format wich is easily copyable?
here is my employee column and on the left-hand side G1, G2 and G3. I would like G1, G2..... Gx is a new column so that I can filter them out as an option and select what I want to pick.
For example, G3 includes 2 characters starting with C. I want that as one group.
Numeric under the G1.
Does this make sense?
