Answer / ziauddin
When u configure a session using update strategy the
session property data driven instructs informatica server
to use the instructions coded in mapping to flag the rows
for insert, update, delete, this is the default option
selected when using a update strategy transformation in a
mapping.

Answer / kamesh
When ever a mapping contains Update Strategy Transformation
the way data needs to be treated is declared in the session
property as Data Driven. This is done by mentioning
DD_UPDATE or DD_INSERT or DD_DELETE in the update strategy
transformation.
A mapping may contain two Update strategy transformations,
1 for inserting and another for updating in two different
pipelines in single mapping.
Therefore, in order session to get executed successfully,
mention Data Driven property in the session properties for
that particular mapping.
