The UpgradeIndex task is used to update search indexes in the background. For parallel operation of V11 and V12 it is used to update the full text search index and the search index for variables when a catalog changes. For this purpose, the OnCatalogChanged trigger must be added to the TimeTable and the UpgradeOnCatalogChanged trigger must be added for the FullTextIndex and the SearchVarsIndex.

The generation of the CommonErpIndex (key UpdateCommonErpIndex) should be deactivated.
