Containerization of Orders Function
Hi Anonymous ,
if my understanding is correct, you can use this function on the order-level:
// fnContainers (Source, MaxBinQtyColName as text, SKUQtyColName as text ) => let //Source = #"myTable (2)"{1}[Partition], //MaxBinQtyColName = "Max Bin Qty (Function Input)", //SKUQtyColName = "SKU Qty (Function Input)", MaxBinQty = List.First(Table.Column(Source, MaxBinQtyColName)), BufferedList = List.Buffer(Table.Column(Source, SKUQtyColName)), Output = List.Skip(List.Generate( () => [RT = 0, Bin = 0, Counter = 0], each [Counter] <= List.Count(BufferedList), each [ RT = if ( [RT] + BufferedList{[Counter]} ) > MaxBinQty then BufferedList{[Counter]} else [RT] + BufferedList{[Counter]} , Bin = if ( [RT] + BufferedList{[Counter]} ) > MaxBinQty then [Bin] + 1 else [Bin], Counter = [Counter] + 1 ], each [Bin] + 1 )) in OutputTo apply it, your code would look like so (also, see the attached file):
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQwMFDSAVFgEkgYg1lKsTpwSSMoiVXSGKLTFCZphCxpApE0h0kagyWNkO00hdlriCwHsdIEq5w5hITJGSHLWUDchCQXCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [#"Order (Function Input)" = _t, #"SKU ID (Function Input)" = _t, #"SKU Qty (Function Input)" = _t, #"Max Bin Qty (Function Input)" = _t, #"Container # (Function Output)" = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Order (Function Input)", Int64.Type}, {"SKU ID (Function Input)", Int64.Type}, {"SKU Qty (Function Input)", Int64.Type}, {"Max Bin Qty (Function Input)", Int64.Type}, {"Container # (Function Output)", Int64.Type}}), #"Grouped Rows" = Table.Group(#"Changed Type", {"Order (Function Input)"}, {{"Partition", each _}}), #"Invoked Custom Function" = Table.AddColumn(#"Grouped Rows", "Container", each fnContainers([Partition], "Max Bin Qty (Function Input)", "SKU Qty (Function Input)")), #"Added Custom" = Table.AddColumn( #"Invoked Custom Function", "Result", each Table.FromColumns(Table.ToColumns([Partition]) & {[Container]}, Table.ColumnNames([Partition]) & {"Container"})), Custom1 = Table.Combine(#"Added Custom"[Result]) in Custom1This technique should also work fairly fast on large tables.
Nathaniel_C In the Sample Data the Headers display the columns that are input columns and what column that shows the expected outcome of the function. The function should only create 1 new column assigning a container number to each SKU within an Order.
Hi Anonymous ,
So another way to look at this would be, a running total of how many containers are needed to fill an order? We are not really assigning a container # to a SKU, because in some cases, a SKU might go into more than 1 container, correct?
Will be offline for awhile...

Nathaniel_C That is correct, Keeping the results at the SKU level (meaning Container # will repat itself if an Order has multiple SKU's). You will not need to break out a SKU across multiple containers. Said another way, you will not need to break a record out into 2 records to fill up 1 container and start another. If the entire SKU Qty cannot fit into the remaining capacity of a container then a new container is assigned to that SKU.
Hi Anonymous
This solution is based on your data submitted. I used your SKU ID to know my place in the table. You may need to add an Index column in Power Query to perform that function instead.
Let me know if you have any questions.
If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos 👍are nice too.
NathanielSum of SKU QTY = SUM(myTable[SKU Qty (Function Input)])RT of SKU QTY = VAR _SKU_ID = MAX ( myTable[SKU ID (Function Input)] ) VAR _order = MAX ( myTable[Order (Function Input)] ) VAR _SKU_QTY = MAX ( myTable[SKU Qty (Function Input)] ) VAR _maxBinQty = MAX ( myTable[Max Bin Qty (Function Input)] ) VAR _calc = CALCULATE ( [Sum of SKU QTY], ALLEXCEPT ( myTable, myTable[Order (Function Input)] ), myTable[SKU ID (Function Input)] <= _SKU_ID ) RETURN ROUNDUP ( DIVIDE ( _calc, _maxBinQty ), 0 )Nathaniel_C Thank you for the quick response!
I have 2 follow up questions / comments:
1. Can this be done as an M code function because I have multiple tables I'd like to apply this logic to then additional transformations to be completed. Completing this step in DAX will not allow me to complete these extra steps (Hence why I placed this question in the Power Query Section).
2. Using SKU ID cannot be used to keep track of where you are because SKU ID can be duplicated in multiple Orders. I've modified the example data set to show you what I mean (Both orders now have SKU's 100 and 200)
3. Your logic does not appear to allow the logic to restart with every new order. The values being assigned to each variable span the entire data set, When they should only span the SKU's within each new Order. See in the example below how when the function gets to Order 2000 the container starts over at 1.
Order (Function Input) SKU ID (Function Input) SKU Qty (Function Input) Max Bin Qty (Function Input) Container # (Function Output) 1000 100 10 30 1 1000 200 20 30 1 1000 300 15 30 2 1000 400 17 30 3 2000 100 5 10 1 2000 200 4 10 1 2000 700 7 10 2 2000 800 3 10 2
