Create rows from 2 tables

I have a refreshable table pulling in "Hub" & "Subset".  I have a "key" table with different criteria based on different options.  This is currently finite and probably brought in through an excel table.  Or, perhaps the code can be built to eliminate the need for the 2nd table?

 

I am in need of creating a finite number of rows based on the refreshable table & key table so it can be filtered in the PBI visual.

 

Here is an example of the items needed from the combined key table & data to be used from the refreshable table.  The desired result is to produce rows from each row of the key table.  Example would be to produce say 70 rows of each unique concat. Example:  Hub = 321, Subset = 7 therefore, 32117001, 32117002, 32117003...32117070; 32117201, 32117202, 32117203...32117270; 32117401, 32117402...32117470; 32117601...32117670

 

HUBGROUPSUBSETTYPESEQUENCE
(dependent)(static)(dependent)(static)(starting #)
 1 001
 1 201
 1 401
 1 601

 

 

Any help would be truy appreciated.

Hi @unknown917 ,

 

Don't know if you have any column to add the number of rows in this case the 70 you can built a formula similar to this:

{ [Hub]*1000000 + [Groupsubset]*1000 + 1..  [Hub]*1000000 + [Groupsubset]*1000 + [Number of rows]}

Full code below:

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjYyVNJRMgdhA6XYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Hub = _t, Groupsubset = _t, #"Number of rows" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Hub", Int64.Type}, {"Groupsubset", Int64.Type}, {"Number of rows", Int64.Type}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each { [Hub]*1000000 + [Groupsubset]*1000 + 1.. [Hub]*1000000 + [Groupsubset]*1000 + [Number of rows]}),
#"Expanded Custom" = Table.ExpandListColumn(#"Added Custom", "Custom")
in
#"Expanded Custom"

@MFelix - Allow me to explain a little more clearly.  Is it possible to merge 2 tables that don't have a primary key?  There may be several hubs with or without multiple subsets ("Seq Order")  but each hub needs to have 70 rows produced for each unique row in the "Key" table.  I have 20 unique keys to be applied

Hi @unknown917 ,

 

You can join the two tables yes, but can you please give me an example of the values on both tables. So I can give you the better code for that.

@MFelix - thank you so much for the help, it is beyond appreciated.  I have figured a way to do it in the 1 table, just repeated the unique keys (I know could have done it more efficiently I'm sure)  but I have run into a snag with an a key entry that only requires a single output instead of 70.  Below, the intend result is 32117888, but I am not getting a return.  What am I missing?

 

[Hub] * 100000 + 2 * 10000 + [Seq Order] * 1000 + 8 * 100 + 88 .. [
Hub
]
* 100000
+ 2 * 10000
+ [Seq Order] * 1000
+ 8 * 100
+ 1
