One of my feature classes, a large file (50K records), cannot be appended to because there is no spatial index. The metadata and geoprocessing history shows that there was an index last spring, when it was last updated. Any reason why this would disappear? I see there is tool to fix it, but all of our SDE privileges are messed up, so I can't run this tool.
It is a 10.1 SQL Server-base database.
Could this indicate an integrity problem with the database overall?
