SYMPTOM
In Strategy Developer, text files imported into attribute qualifier prompts can be delimited by carriage returns, tabs, commas, and semicolons. However, the same does not apply in Strategy Web. Different behaviors are observed for different delimiters.
Carriage Return (semicolon (;) ): The text file will import successfully and each delimited string will be imported as a single element. All Web Preferences and Settings will be observed. In the example below, the 'Maximum number of elements to import' preference is set at 3, thus an error is encountered.

Sample Code/Error
The number of elements to import is larger than the maximum number permitted for this project. The imported list will be truncated to 3 elemets. Please contact your administrator for more information.

Tab: The text file will ignore the delimiter. The entire file will be interpreted as a single string, and the import will consist of one element as shown in the example below.

STEPS TO REPRODUCE:
CAUSE
This is a known issue in Strategy Web 9.4.1 and above.
ACTION:
Strategy will continue to investigate and post updates as soon as they are available.
WORKAROUND:
If possible, use semicolons as the delimiter, as it imports the number of elements correctly and also obeys the maximum number of elements to import restriction.
