Stock on Hand reducing quantity

[Anonymous]

Hi,

I have a few materials which consume the same bill of material, in order to produce a finished product.

Currently, I have a very simple subtraction formula.

But it is now showing that the stock on hand is reducing for the bill of material.

Finished product	Bill of material	Stock on hand Bill of material		Due to deliverer finished product	Correct Variance	Incorrect Variance
390555zGDE	390555ZZDE1	4317		978	3339	3339
390555zGDE	390555ZZDE1	4317		2007	1332	2310
390555zGDE	390555ZZDE1	4317		1540	-208	2777

The stock on hand for material 390555ZZDE1 = 4317,  but I need it to reduce with each consumption of the material.

Will you be able to help with this, please?

Regards and Thanks

Hi @Anonymous ,

You need to create an index column first in power query editor to calculate.

If you do not want the index column load into your table, you can use power query for calculations throughout. The whole query would be like this:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMrY0MDU1rXJ3cVXSgXKiolxcDYE8E2NDcyBlaW6hFKtDjEojAwNzIpUampoYKMXGAgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Finished product" = _t, #"Bill of material" = _t, #"Stock on hand Bill of material" = _t, #"Due to deliverer finished product" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Finished product", type text}, {"Bill of material", type text}, {"Stock on hand Bill of material", Int64.Type}, {"Due to deliverer finished product", Int64.Type}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 1, 1, Int64.Type),
    #"Added Custom" = Table.AddColumn(#"Added Index", "Result", each [Stock on hand Bill of material] -List.Sum(List.Range(#"Added Index"[Due to deliverer finished product],0,[Index]))),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Index"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Removed Columns",{{"Result", Int64.Type}})
in
    #"Changed Type1"

If you want to use DAX to calculate, the index column would be kept and you can create a calculated column like this:

Result = 
[Stock on hand Bill of material]
    - CALCULATE (
        SUM ( 'Table_DAX'[Due to deliverer finished product] ),
        FILTER ( 'Table_DAX', 'Table_DAX'[Index] <= EARLIER ( 'Table_DAX'[Index] ) )
    )

I am not quite sure how you have set up your files and the calculations. Better, you could share a sample PBIX file explaining the issues and the desired results.
