Problem calculating flowfield in DAX

[data_mp_97]

Hello everyone,I have a problem calculating a flowfield (calculated column that cannot be exported) that comes from Business Central.
The formula for this flowfield in Visual Studio and with AL code is the following:

field(5752; "Completely Shipped"; Boolean)

{

      CalcFormula = min("Sales Line"."Completely Shipped" where("Document Type" = field("Document Type"),

                                                                "Document No." = field("No."),

&nbsp;                                                               Type = filter(<> " "),

&nbsp;                                                               "Location Code" = field("Location Filter")));

&nbsp;     Caption = 'Completely Shipped';

&nbsp;     Editable = false;

&nbsp;     FieldClass = FlowField;

I have replicated it like this in DAX:

Completely Shipped =

VAR CurrentDocumentType = SELECTEDVALUE('salesheader36'[DocumentType])

VAR CurrentDocumentNo = SELECTEDVALUE('salesheader36'[No])

VAR LineasFiltradas =

    FILTER(

        'salesline37',

        'salesline37'[DocumentType] = CurrentDocumentType &&

        'salesline37'[DocumentNo] = CurrentDocumentNo &&

        'salesline37'[Type] <> BLANK()

    )

VAR MinCompletado =

    MINX(LineasFiltradas, INT('salesline37'[CompletelyShipped]))

RETURN

    MinCompletado

I skipped the locationfilter part since it is a flowfilter that I was told is not necessary.The results of my DAX formula, when I apply it to the general formula, do not match the results in Business Central.

Any ideas? I have tried many ways and it does not give me the result..

If you are creating a calculated column then SELECTEDVALUE will not work - that works only in a filter context, not in a row context. If you are creating the column on the table 'salesheader36' then you can use

Completely Shipped =
VAR CurrentDocumentType = 'salesheader36'[DocumentType]
VAR CurrentDocumentNo = 'salesheader36'[No]
VAR LineasFiltradas =
    FILTER (
        'salesline37',
        'salesline37'[DocumentType] = CurrentDocumentType
            && 'salesline37'[DocumentNo] = CurrentDocumentNo
            && 'salesline37'[Type] <> BLANK ()
    )
VAR MinCompletado =
    MINX ( LineasFiltradas, INT ( 'salesline37'[CompletelyShipped] ) )
RETURN
    MinCompletado

No, but I was creating a DAX measure (Completely Shipped), not a calculated column.Then I use that DAX measure here:

VentasDistriNoAlbaranadas_Final22(CB)=
CALCULATE(DISTINCTCOUNT('salesheader36'[No]),
'salesheader36'[PostingDate] >= DATE(2025, 8, 1),
'salesheader36'[PostingDate] <= DATE(2025, 10, 2),
'salesheader36'[$Company] = "DIST",
FILTER('salesline37',[Completely Shipped] = 0))

Maybe the error can be seen here..

Can you please share the error you got?

I think the issue is that when you are calling the [Completely Shipped] measure from within the FILTER clause 'salesheader36'[DocumentType] and 'salesheader36'[No] do not have single values so SELECTEDVALUE will return a blank.

Without knowing the relationships between tables it is difficult to suggest a solution, but I think the general approach would be to build a table variable containing document type and number and whether it is completely shipped or not, then get a distinct count from that table.

Hi @data_mp_97 ,

You can create a calculated column first,
Completely Shipped =
VAR CurrentDocumentType = 'salesheader36'[DocumentType]
VAR CurrentDocumentNo = 'salesheader36'[No]
VAR LineasFiltradas =
FILTER (
'salesline37',
'salesline37'[DocumentType] = CurrentDocumentType
&& 'salesline37'[DocumentNo] = CurrentDocumentNo
&& NOT ISBLANK ( 'salesline37'[Type] )
)
RETURN
MINX ( LineasFiltradas, INT ( 'salesline37'[CompletelyShipped] ) )


and thn create a meausure taking the calculated column base:- 

VentasDistriNoAlbaranadas_Final22(CB) =

CALCULATE (
DISTINCTCOUNT ( 'salesheader36'[No] ),
'salesheader36'[PostingDate] >= DATE ( 2025, 8, 1 ),
'salesheader36'[PostingDate] <= DATE ( 2025, 10, 2 ),
'salesheader36'[$Company] = "DIST",
'salesheader36'[Completely Shipped] = 0
)

Thankyou, @johnt75, and @grazitti_sapna, for your responses.

Hi data_mp_97,

We appreciate your inquiry through the Microsoft Fabric Community Forum.

Based on my understanding, the discrepancy arises because the Business Central FlowField is evaluated at the header level, that is, it computes the minimum of the related sales lines. In your DAX, the measure was being evaluated at the line level, which caused a context mismatch. In addition, the FlowField excludes empty Type values and may include a Location filter, which were not fully replicated in your measure.

Please follow the suggested approach below which may help to resolve the issue:

1. Compute the FlowField logic at the header level and then apply it within your calculation, as shown:

VentasDistriNoAlbaranadas_Final22(CB) =

CALCULATE(

DISTINCTCOUNT('salesheader36'[No]),

'salesheader36'[PostingDate] >= DATE(2025, 8, 1),

'salesheader36'[PostingDate] <= DATE(2025, 10, 2),

'salesheader36'[$Company] = "DIST",

FILTER (

VALUES('salesheader36'[No]),

VAR MinComp =

CALCULATE(

MINX(

FILTER (

'salesline37',

TRIM(COALESCE('salesline37'[Type], "")) <> ""

&& 'salesline37'[LocationCode] = SELECTEDVALUE(LocationTable[LocationCode])

),

IF('salesline37'[CompletelyShipped],1,0)

)

)

RETURN COALESCE(MinComp, 0) = 0

)

)

Using VALUES('salesheader36'[No]) ensures that the calculation is performed per header, analogous to FlowFields in Business Central. The inner MINX replicates the FlowField’s minimum across related sales lines. The TRIM(COALESCE(...)) <> "" expression corresponds to Business Central’s Type <> " " condition.
