You cannot create a hash 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 with a new hash index, use the following general procedure:

  1. Create the new hash index on the table on the target system.
  2. Extract a fresh dynamic AMP sample from the target system.
  3. Apply the fresh sample to the source system.
