SYMPTOM:
Within the attribute editor in Strategy Developer 9.4.x the user is trying to delete an attribute form which has no expression but it cannot be deleted due to dependents. This attribute form at one time had an expression that was linked to a freeform SQL report but then later the expression was removed.


CAUSE:
This condition has been reported in Strategy 9.4.x, however its root cause is unknown.
ACTION:
Please contact Strategy Technical Support for further assistance. In order to track down the cause of the inconsistency, customers encountering this issue should make note of Schema-related changes, Object Migrations, or error messages prior to experiencing the problem. Change Journaling, if it has been enabled, can help in preserving this information.
WORKAROUND:
Having this form will not lead to errors so it can be left within the attribute for later use if desired.
