create two calculated columns (Concatenatex)

Hi Kris48 

To create the two calculated columns "Module_Ver 2" and "Value_Ver 2" in Power BI, you can use the CONCATENATEX function in DAX. Here's how you can do it:

Assumptions:

• Table Name: Replace 'YourTable' with the actual name of your table.
• Grouping Column: Replace 'KeyColumn' with the column you want to group by (e.g., an ID or date).
• Columns to Concatenate: 'Module' and 'Value' are the columns you want to concatenate.

Steps:

1. Module_Ver 2 Column

Create a new calculated column in your table with the following DAX formula:

Module_Ver 2 = 
VAR CurrentKey = 'YourTable'[KeyColumn]
RETURN
CONCATENATEX(
    FILTER(
        'YourTable',
        'YourTable'[KeyColumn] = CurrentKey
    ),
    'YourTable'[Module],
    ", "
)

2. Value_Ver 2 Column

Create another calculated column with this formula:

Value_Ver 2 = 
VAR CurrentKey = 'YourTable'[KeyColumn]
RETURN
CONCATENATEX(
    FILTER(
        'YourTable',
        'YourTable'[KeyColumn] = CurrentKey
    ),
    'YourTable'[Value],
    ", "
)

Explanation:

• CurrentKey: Captures the value of the grouping key for the current row.
• FILTER: Filters the table to include only rows with the same key as the current row.
• CONCATENATEX: Concatenates the specified column's values (e.g., 'Module' or 'Value') from the filtered table, separated by ", ".

Alternative Using Power Query:

If you prefer to do this in Power Query:

1. Group By Key Column:

   • Go to Home > Group By.
   • Group by your key column (KeyColumn).
   • Create two aggregation columns:
     • Module_Ver 2: Use the operation All Rows.
     • Value_Ver 2: Use the operation All Rows.

2. Add Custom Columns:

   • Add a custom column for Module_Ver 2:

= Text.Combine([GroupedRows][Module], ", ")

Add a custom column for Value_Ver 2:

= Text.Combine([GroupedRows][Value], ", ")

1. Cleanup:

   • Remove unnecessary columns resulting from the grouping.
   • Ensure only the desired columns remain.

Note:

• Replace 'YourTable', 'KeyColumn', 'Module', and 'Value' with the actual names from your dataset.
• Ensure that your data model relationships support the calculations.

By following these steps, you should be able to create the two new columns as per your requirements.
