TOPN SUMMARIZE with SWITCH measures

Hi VoijaRisa 

Based on your detailed description, I have added some steps to the actions you have already taken, and in my simple tests it is working. I hope the following steps will be helpful to you.

Here's my data model:

1. Create the "Total Amount Paid (USD) Sum" measure in the same way as you used it.

2. Create separate measures to calculate Top5 for different date selections.

Top 5 Ship Date = 
SUMX(
    TOPN(
        5,
        ADDCOLUMNS(
            SUMMARIZE(
                'Shipments',
                'Shipments'[Origin],
                'Shipments'[Destination]
            ),
            "Total Paid USD", [Total Amount Paid (USD) Sum]
        ),
        [Total Paid USD], DESC
    ),
    [Total Paid USD]
)

Top 5 Invoice Date = 
CALCULATE(
    SUMX(
        TOPN(
            5,
            ADDCOLUMNS(
                SUMMARIZE(
                    'Shipments',
                    'Shipments'[Origin],
                    'Shipments'[Destination]
                ),
                "Total Paid USD", [Total Amount Paid (USD) Sum]
            ),
            [Total Paid USD], DESC
        ),
        [Total Paid USD]
    ),
    USERELATIONSHIP('Date'[DATE], 'Shipments'[INVOICE_DATE])
)

Top 5 Processed Date = 
CALCULATE(
    SUMX(
        TOPN(
            5,
            ADDCOLUMNS(
                SUMMARIZE(
                    'Shipments',
                    'Shipments'[Origin],
                    'Shipments'[Destination]
                ),
                "Total Paid USD", [Total Amount Paid (USD) Sum]
            ),
            [Total Paid USD], DESC
        ),
        [Total Paid USD]
    ),
    USERELATIONSHIP('Date'[DATE], 'Shipments'[PROCESSED_DATE])
)

3. Combine the Top5 measures created above into one measure.

Top 5 = 
VAR DateSelection = SELECTEDVALUE('Date Slicer Choices'[Date Choice])

RETURN
SWITCH(
    TRUE(),
    DateSelection = "Invoice Date", [Top 5 Invoice Date],
    DateSelection = "Processed Date", [Top 5 Processed Date],
    DateSelection = "Ship Date", [Top 5 Ship Date]
)

4. Create a card visual with Top 5 measure.

5. Here is final result:
