    Thanks for your help.

    I figured out different solution.

    Instead of using [ALL (Category)] I used [REMOVEFILTERS(Category)] and magically performance has been fixed and now everything works as I expected.

    Now my measure look like this:

    _test = 
    VAR __Total_STD = 
        CALCULATE([_SumOfCol_n1] - [_SumOfCol_49] - [_SumOfCol_9] - [_SumOfCol_45] - [_SumOfCol_50]
            , V_Order_Cost_Breakdown_Pivot_ProfitabilityRep[Attribute_Nr] = 6
            , REMOVEFILTERS(Category)
        )
    VAR __Total_QUO = 
        CALCULATE([_SumOfCol_n1] - [_SumOfCol_49] - [_SumOfCol_9] - [_SumOfCol_45] - [_SumOfCol_50]
            , V_Order_Cost_Breakdown_Pivot_ProfitabilityRep[Attribute_Nr] = 12
            , REMOVEFILTERS(Category)
        )
    VAR __Total = SWITCH(SELECTEDVALUE(Category[Category_Group_Nr])
                        , 1 , __Total_STD
                        , __Total_QUO
                )
    VAR __Result =
        SWITCH(SELECTEDVALUE(Category[Category_ShortDesc])
            , "Total", __Total
            , "1000SQM", DIVIDE(__Total, [_SumCOL_NetSqm]) * 1000
            , "1000KG", DIVIDE(__Total, [_SumCOL_OrderedWght]) * 1000
            , "1000PCS", DIVIDE(__Total, [_SumCOL_OrderedQty]) * 1000
        )
RETURN
    __Result

Hi Jarecki 

try to replace 

SELECTEDVALUE ( Category[Category_Group] )
by

MAXX ( SUMMARIZE ( FactTable, Category[Category_Group] ), Category[Category_Group] )

 

and replace SELECTEDVALUE ( Category[Category_ShortDesc] )

by

MAXX ( SUMMARIZE ( FactTable, Category[Category_ShortDesc] ), Category[Category_ShortDesc] )

Hi,
thanks for quick reply.

So I made a change regarding to your suggestions, but result is the same.
When I'm trying to add another field from different related table I get "not enought memory" error

_test = 
VAR __Category = 
            IF(MAXX(SUMMARIZE ( V_Order_Cost_Breakdown_Pivot_ProfitabilityRep
                                , Category[Category_Group] 
                            )
                    , Category[Category_Group] 
                ) = "Standard Cost", 6, 12
            )

VAR __Total =
    CALCULATE(
        [_SumOfCol_n1]
            - [_SumOfCol_49]
            - [_SumOfCol_9]
            - [_SumOfCol_45]
            - [_SumOfCol_50]
        , V_Order_Cost_Breakdown_Pivot_ProfitabilityRep[Attribute_Nr] = __Category
        , ALL(Category)
    )
VAR __Result =
    SWITCH(
        MAXX(SUMMARIZE(V_Order_Cost_Breakdown_Pivot_ProfitabilityRep
                        , Category[Category_ShortDesc] 
            )
            , Category[Category_ShortDesc] 
        ),
        "Total", __Total,
        "1000SQM", DIVIDE(__Total, [_SumCOL_NetSqm]) * 1000,
        "1000KG", DIVIDE(__Total, [_SumCOL_OrderedWght]) * 1000,
        "1000PCS", DIVIDE(__Total, [_SumCOL_OrderedQty]) * 1000
    )
RETURN
    __Result
