Consider the following guidelines when you configure the session properties for success files:
If you do not specify a directory for the success file as a session property, the PowerCenter Integration Service writes an empty file to the following directory:
$PMTargetFileDir
.
The PowerCenter Integration Service generates the success file with the following naming convention:
<sessionName>_<timestamp>_success.csv
.
If you do not map a primary key column in a mapping, the insert, update, upsert, and delete operations fail.
