data warehouse backend as source of IM

[jplarios]

question:
if I created an information map on top of data whose source resides in a data warehouse back-end such as sql server or oracle, anyone know if it would use passthrough such that when the join is done in report time, it takes advantage of the back end optimization?

If the information map does not introduce SAS-specific SQL elements to the generated query such as SAS functions or formats, then normal PROC SQL implicit pass-through should work as it normally would for a user created query.

Thanks Julierd! I did not think about SAS formats and functions not working since using the passthrough.
