Error: 1

1. Use the GUI / CLI for consolidation of Central into measurement base
2. Consolidation fails with error Failed to run ADG_COMPUTE_DELTA_SNAPSHOTS

This error occurs during consolidation in measurement database, when some snapshots with the same functional date have disappeared in the central database but still exists in the measurement base.

1. Do a full-reset of the measurement base and do a re-consolidation of all the Central Bases.
