Error 90193: A 'apparel_size' value 'm' is not less than 'apparel_size' value 'm'

Error Description

The "Error 90193: A 'apparel_size' value 'm' is not less than 'apparel_size' value 'm'" error indicates that the apparel_size values provided are either the same for both the start and end of the range or that they are incorrectly defined. When specifying a size range, the starting size must be less than the ending size to ensure a logical and valid size range.

Common Causes:

  1. Identical Size Values: The start and end sizes in the range are the same.
  2. Incorrect Size Order: The starting size is not less than the ending size.
  3. Data Entry Errors: Mistakes in entering the size values leading to logical inconsistencies.

Error Solution

To resolve the "Error 90193: A 'apparel_size' value 'm' is not less than 'apparel_size' value 'm'," follow these steps:
