time. | |
Thanks for the details. I think they confirm that deletes are using full table scan of the master table. Assuming the table is
very large, TD goes for the table lock to prevent performance problems. I would experiment with the PI defined as (country_cd,
customer_nbr, material_nbr).

Pleasure. Please keep us posted on the progress. 30 country shops are rare and such feedback is very useful.
