To control Report generates during application builds, build your Reports when the application build completes. Set the Deploy Reports configuration property, under the Build Target Filter category of the Folder to True.

Controlling the Number of Report Generates

Use the Application Builder command MAXREPGEN to control the number of concurrent Report generates.

From Builder, you can request more than one compile task, but this is ultimately limited by the MAXREPGEN setting.

Report source files remain named as system/WORK/report.
