SYMPTOM:
No attribute element is available when answering an attribute element list prompt or View filter from Strategy Developer or Web. Attribute browsing is disabled for all attributes, and no error message appears.

CAUSE:
The 'Element display' option in the Attribute Editor is set to 'Locked'.

The 'Locked' option will cause no attribute elements of a given attribute to be shown within the System Hierarchy in the Data Explorer or all types of attribute element browsing, including attribute element prompts, View Filter or Report Filter editors.
ACTION:
Change the option to either 'Unlocked' or 'Limit' in the Attribute Editor.
