FrameWork Manager 10.2.2 - Import metadata

## English Version
With Cognos FrameWork Manager 10.2.2, we import Teradata views in DQM mode.
The response times are very long.
We analyze the queries sent to Teradata. The query (in the use case) lasts longer than 4 min 30s.
It uses tables systems : DBC.Columns and DBC.Tables.
Our Teradata expert tells us that we must use DBC.ColumnsV and DBC.TablesV views (for Teradata 14.10) instead of DBC.Columns and DBC.Tables.
They give the same result with much higher performance (few seconds max).

Can you modify the code to use these views when querying Teradata system tables?
We found this at FrameWork Manager, but may need to also be applied to other Business Intelligence tools

We opened a PMR with IBM France support. The number of PMR is 18117,650,706.
We also contacted our Lab Advocate Guillaume Senneville.

Thank you in advance for your consideration of this point.
Best Regards,


## Version Française
Avec Cognos FrameWork Manager 10.2.2, nous importons des vues Teradata en mode DQM.
Les temps de réponses pour importer ces vues sont très longs.
Nous avons analyser les requêtes envoyées à Teradata. La requête suivante dure plus de 4 min 30s.
Elle utilise les tables systèmes DBC.Columns et DBC.Tables.
Notre expert Teradata nous indique qu'il faut utiliser les vues DBC.ColumnsV et DBC.TablesV (pour Teradata 14.10). Elles donnent le même résultat avec des performances nettement supérieures (qlqs secondes max).

Pouvez-vous faire le nécessaire pour utiliser ces vues lors de l'interrogation des tables systèmes de Teradata ?
Nous avons constaté ce point au niveau de FrameWork Manager, mais peut-être qu'il faut l'appliquer également sur d'autres outils de Business Intelligence

Nous avons ouvert un PMR auprès du support IBM France. Le numéro est 18117,650,706.
Nous avons également contacté notre Lab Advocate Guillaume Senneville.

Merci d'avance pour la prise en compte de ce point.
