The AI Secret to Flawless Power BI Date Tables (No Code Hack!)

Unlock custom Power BI date tables in seconds! Watch how AI writes the DAX for you. Fast, easy, and perfect for any report. #PowerBI #AI #DateTable #dax AI PROMPT used in the Video: 🎯 Set the AI Role: Act as a Power BI expert specializing in DAX formula creation. 🏁 Define the Goal: Your primary goal is to generate the complete DAX code required to create a calculated Date Table within Power BI. 📊 Specify Data Source & Range: Date Table range: Dynamic, from MIN to MAX of USER_DATE_COLUMN_PLACEHOLDER within USER_TABLE_NAME_PLACEHOLDER. AI must generate valid DAX for this range using these placeholders with correct square bracket syntax (e.g., MIN(USER_TABLE_NAME_PLACEHOLDER[USER_DATE_COLUMN_PLACEHOLDER])). ⚙️ Detail the Requirements: AI NOTE: Prompt avoids square brackets (for YouTube). In logic examples below, "the base Date column" refers to the [Date] column generated by CALENDAR. Your final DAX output MUST use standard square brackets for all column/measure references (e.g., [Date], USER_TABLE_NAME_PLACEHOLDER[USER_DATE_COLUMN_PLACEHOLDER]). Generate a single DAX expression that creates a calculated table named 'DateTable'. This table must include the following columns, derived from "the base Date column": Date: The base date column from USER_TABLE_NAME_PLACEHOLDER[USER_DATE_COLUMN_PLACEHOLDER]). Data type: Date. Year: Numeric calendar year. Logic example: YEAR function applied to the base Date column. Month Number: Numeric month (1-12). Logic example: MONTH function applied to the base Date column. Month Name: Full text name of the month. Logic example: FORMAT function applied to the base Date column, using "MMMM". Month Name Short: Short text name of the month. Logic example: FORMAT function applied to the base Date column, using "MMM". Calendar Quarter Number: Numeric calendar quarter (1-4). Logic example: QUARTER function applied to the base Date column. Calendar Quarter: Text representation (e.g., "Q1"). Combine "Q" with the result of QUARTER function applied to the base Date column. Day of Week Number: Numeric (Monday=1, Sunday=7). Logic example: WEEKDAY function applied to the base Date column, using parameter 2. Day of Week Name: Full text name. Logic example: FORMAT function applied to the base Date column, using "dddd". Day of Week Name Short: Short text name. Logic example: FORMAT function applied to the base Date column, using "ddd". Year Month: Text for sorting (e.g., "2024-01"). Logic example: FORMAT function applied to the base Date column, using "YYYY-MM". Week Number: Numeric (week starting Monday). Logic example: WEEKNUM function applied to the base Date column, using parameter 2. Day of Month: Numeric. Logic example: DAY function applied to the base Date column. Financial Year: Numeric (financial year starts April 1st). Logic example: IF MONTH of the base Date column is less than 4, THEN (YEAR of the base Date column minus 1), ELSE (YEAR of the base Date column). Financial Quarter: Text (e.g., "FQ1", financial year starts April 1st). Logic example: "FQ" & CEILING((MOD(MONTH of the base Date column minus 4 plus 12, 12) plus 1) divided by 3, 1). Month Year: Text (e.g., "Jan 2024"). Logic example: FORMAT function applied to the base Date column, using "MMM yy". Day Type: Text: "Weekend" or "Weekday". Logic example: IF WEEKDAY of the base Date column (using parameter 2) is greater than or equal to 6, THEN "Weekend", ELSE "Weekday". (Note: Holiday logic is separate). ISO Weeknumber: Text ('YYYY-Www'). Logic hint: The ISO Year part often uses YEAR of (the base Date column minus WEEKDAY of the base Date column with parameter 2, plus 3). The ISO Week part uses WEEKNUM of the base Date column with parameter 21. Combine and format appropriately. Week Ending Date: Date (e.g., Sunday). Logic example: The base Date column plus 7 minus WEEKDAY of the base Date column (using parameter 2). Data type: Date. Ensure the final output is only the DAX code block, ready to be pasted into Power BI. The DAX code must use ADDCOLUMNS and CALENDAR. The dynamic range for CALENDAR should be determined by applying the MIN and MAX aggregate functions to the USER_DATE_COLUMN_PLACEHOLDER from the USER_TABLE_NAME_PLACEHOLDER. (Your generated DAX should look like CALENDAR(MIN(USER_TABLE_NAME_PLACEHOLDER[USER_DATE_COLUMN_PLACEHOLDER]), MAX(USER_TABLE_NAME_PLACEHOLDER[USER_DATE_COLUMN_PLACEHOLDER])), using the actual placeholder names provided by the user, correctly formatted with square brackets). IMPORTANT NOTE You'll need to inform the AI (or edit the prompt below) with your specific *** table and column names*** . Replace USER_TABLE_NAME_PLACEHOLDER with the name of your main data table (e.g., SalesData, Financials, etc.). Replace USER_DATE_COLUMN_PLACEHOLDER with the name of the date column within that table which determines the overall date range (e.g., OrderDate, TransactionDate, etc.). The AI is instructed to convert these placeholders into proper DAX.
