You cannot drop a secondary index for a table while that table is subject to dynamic AMP sample emulation. To disable dynamic AMP sampling, contact the Teradata Support Center.
To use dynamic AMP sampling on the table from which you dropped the secondary index, use the following general procedure:
- Drop the secondary index from the table on the target system.
- Extract a fresh dynamic AMP sample from the target system.
- Apply the fresh sample to the source system.
