RANKX shows different result after using Union

[Anonymous]

Hello Community team,

I have a table name KPI with many measures behind, one of which is RANKX, which rankes the value based on a calculated measures before. The final purpose is to assign Score based on their rank.

All formula go well and shows the correct ranking and score as my logic.

However, to combin with other lists, I use UNION to append with other 2 tables, and the score goes wrong. I check details and assume that the Rank is the reason.

Could you please help to advise how I should set up the Rank to get the same result in the origin table and unioned table?

Thank you so much

EBIT_BOT = 
IF(
    [Ebit_lastest] <> 0, 
    RANKX(
        FILTER(
            ALLSELECTED(GC_Masterdata[Company Code], GC_Masterdata[Konzerngesellschaft Name]),
            [Ebit_lastest] <> 0
        ), 
        [EBIT_change], 
        ,
        ASC,
        Dense
    )
)


All = UNION(
    selectcolumns(GC_Masterdata,"Area",GC_Masterdata[Audit-Area], "Object",GC_Masterdata[Konzerngesellschaft Name], "Score", [GC_Score]),
    SELECTCOLUMNS(Process, "Area",Process[Audit-Area], "Object",Process[Konzerngesellschaft Name], "Score", Process[Process_Score]),
    SELECTCOLUMNS(Project, "Area",Project[Audit-Area], "Object",Project[Konzerngesellschaft Name], "Score", Project[Project_Score]),
)

Hi @Anonymous 

Could you please provide more raw data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution. You can refer the following links to share the required info:

)
//I just modified your measure but make sure to replace [Rank_KPI], [Rank_Process], and [Rank_Project] with the actual names of your calculated rank columns in each respective table.

Hello Mr. Hasnain,

Actually the EBIT_BOT is rank already, so I don't need to add other collumns (Rank KPI). My problem is that EBIT_BOT measure gives me different result between the original table KPI, and unioned  table All.
