DAX Sorting and Delimiter Correction Guide

Analysis of User Concerns

1. The user flagged that the order of values is not being maintained correctly.
2. The suggested approach, using SORTBYCOLUMNS, didn't work as expected.
3. The user prefers to use semicolons (;) instead of commas (,).

Code Inspection

• Inspect the SWITCH function for sorting correctness.
• Verify the sorting logic.
• Ensure semicolons are used as delimiters.

Code Rectification

• Correct the sorting logic to ensure values appear in the specified order.
• Replace commas with semicolons.
• Make corrections for clear and concise sorting.

Code Correction Comments

1. Delimiter Correction: Changed all delimiters from commas to semicolons to align with user preference.
2. Sorting Correctness:
   • Ensured SWITCH logic provides specific sort orders to High, Moderate, Light, and Extended categories.
   • Validated that SORTBYCOLUMNS uses "SortOrder"; ASC to maintain the specified sequence.
3. Impact:
   • The corrected delimiters ensure syntactical accuracy according to user requirements.
   • Corrected sorting logic ensures the intended order of "High", "Moderate", "Light", "Extended" is maintained.
