Dedicate a machine to assembling and building packages. This machine must not be used for developing or executing the application being deployed. A dedicated machine allows you to test and rebuild Versions and Patches without inadvertently including any application modifications.
On the dedicated machine, install a full version of LANSA. LANSA refers to this as the Deployment System.
When development has finished, ensure that each finished application is moved to your Deployment System. You can then construct, or reconstruct the package from a controlled environment without the risk of including unexpected changes.
