The amount of detail that logs contain depends on the tracing level that you set. You can configure tracing levels for each transformation or for the entire session. By default, the Integration Service uses tracing levels configured in the mapping.

Setting a tracing level for the session overrides the tracing levels configured for each transformation in the mapping. If you select a normal tracing level or higher, the Integration Service writes row errors into the session log, including the transformation in which the error occurred and complete row data. If you configure the session for row error logging, the Integration Service writes row errors to the error log instead of the session log. If you want the Integration Service to write dropped rows to the session log also, configure the session for verbose data tracing.

Set the tracing level on the Config Object tab in the session properties.

The following table describes the session log tracing levels:

You can also enter tracing levels for individual transformations in the mapping. When you enter a tracing level in the session properties, you override tracing levels configured for transformations in the mapping.
