SYMPTOM:
When a user attempts to run a Report Services document in Strategy Developer 9.x, the error below is thrown:
Sample Code/Error
Error(s) occurred while loading schema: DSSSQLEngine: Schema loading error: Population Exception: The object shown in the following hierarchy no longer exists in schema: -Link-Base Attribute FormCOM interface error.
Message from GetErrorInfo : Index out of range[].
CAUSE:
In this occurence, an Index out of range error is a symptom of a metadata inconsistency in an Attribute's forms. It is very likely that the internal representation of the attribute contains X number of forms but its supporting Table object says that it contains Y forms (X not equal to Y)..
ACTION:
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.
