The calculation DATEPART('iso-weekday', [Order Date])=1 or DATEPART('iso-weekday', [Order Date])=7 is recommended because the ISO standard considers Monday as the first day of the week (1) and Sunday as the last day (7). This calculation will correctly identify Saturdays and Sundays regardless of the locale settings of the workbook's data source, ensuring that the report includes these days as specified by the client.

To accurately identify weekends across different locale settings, using the 'iso-weekday' component is reliable as it is consistent across various locales:

ISO Weekday Function: The ISO standard treats Monday as the first day of the week (1), which makes Sunday the seventh day (7). This standardization helps avoid discrepancies in weekday calculations that might arise due to locale-specific settings.

Identifying Weekends: The calculation checks if the 'iso-weekday' part of the date is either 1 (Sunday) or 7 (Saturday), thereby correctly identifying weekends regardless of the locale settings.

Handling Locale-Specific Settings: Using ISO standards in date functions allows for uniform results across systems with differing locale settings, essential for consistent reporting in global applications.

The most user-friendly solution is to use Dynamic Zone Visibility in combination with a Show/Hide Button. This approach allows the dashboard to dynamically display only the relevant quick filters based on the viewer's selection of shops or warehouses, thus reducing clutter and focusing the user's attention on applicable filters. The Show/Hide Button further enhances the user experience by allowing viewers to toggle the visibility of the filter container, providing a clean and organized dashboard interface1.

Comprehensive and Detailed Explanation From Exact Extract:

Tableau documentation explains:

Tableau Public

Free platform.

Allows public sharing and embedding of fully interactive dashboards.

Ideal for small datasets and infrequent updates.

Does not require user-based licensing.

Embedding is unrestricted because all content is publicly visible.

This perfectly matches the scenario:

Public-facing website

Low cost priority

Small dataset

Manual, infrequent updates

Why the other options are incorrect:

A . Tableau Cloud (per user)

Requires paid licenses.

Does not allow unrestricted public embedding without expensive add-ons.

Designed for secure internal use, not public web-wide embedding.

C . Tableau Embedded Analytics

A paid embedding solution requiring proper licensing.

Designed for large-scale, secure, programmatic embedding --- too costly for this use case.

D . Tableau Server (per core)

Requires server infrastructure & licensing.

Far more expensive than Tableau Public.

Thus, Tableau Public is the correct, cost-effective solution.

Comparison guides showing Tableau Cloud/Server require licensing for embedding.

Moving calculations to the data layer and materializing them in the extract can significantly improve the performance of reports in Tableau. The calculation ZN([Sales])*(1 - ZN([Discount])) is a basic calculation that can be easily computed in advance and stored in the extract, speeding up future queries. This type of calculation is less complex than table calculations or LOD expressions, which are better suited for dynamic analysis and may not benefit as much from materialization12.

Given that all files share the same schema and have a common element in their file names, the wildcard union is an optimal approach to combine these files before performing any transformations. This strategy offers the following advantages:

Efficient Data Combination: Wildcard union allows multiple files with a common naming scheme to be combined into a single dataset in Tableau, streamlining the data preparation process.

Uniform Schema Handling: Since all files share the same schema, wildcard union ensures that the combined dataset maintains consistency in data structure, making further data manipulation more straightforward.

Pre-Transformation Combination: Combining the files before applying transformations is generally more efficient as it reduces redundancy in transformation logic across multiple files. This means transformations are written and processed once on the unified dataset, rather than repeatedly for each individual file.

Wildcard Union in Tableau: This feature simplifies the process of combining multiple similar files into a single Tableau data source, ensuring a seamless and efficient approach to data integration and preparation.

Comprehensive and Detailed Explanation From Exact Extract:

The requirement is:

Compute total sales per customer, not per transaction.

Then compute the average of those customer totals, grouped by region.

Tableau documentation states that FIXED LOD expressions are used to calculate values at a specific level of granularity regardless of the view.

To solve the business need:

Step 1:

Calculate total customer sales for each Customer ID within each Region:

{ FIXED [Customer ID], [Region] : SUM([Sales Amount]) }

This produces one number per customer per region.

Step 2:

Compute the average of those totals:

AVG( { FIXED [Customer ID], [Region] : SUM([Sales Amount]) } )

This yields:

Average total customer sales by region

This is exactly option C.

Why the other options are incorrect:

A . EXCLUDE Region: Would combine regions and incorrectly calculate overall totals.

B . FIXED Region: AVG(Sales Amount): Computes average of line-level sales, not customer totals.

D . FIXED Customer ID + Region: AVG(Sales Amount): Averages individual transactions, not customer totals.

Only option C matches the required two-step logic.

LOD Expressions: FIXED for computing customer-level aggregates.

Nested LOD usage for first calculating customer totals, then averaging them at a higher level.

Tableau guidance: SUM inside FIXED for per-customer totals, AVG outside for averaging customers.
