Restrictions on Creating a Join Index on a Table Concurrent With Dynamic AMP Sample Emulation on That Table - Analytics Database - Teradata Vantage

You cannot create a join 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 join index, use the following general procedure.

1. Create the new join 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.
