These progressions are naturally recorded in the transport directory, which is a unique information document area on the DEV server. These progressions are transported in into the QAS framework, where they are tried to ensure that they work legitimately. On the off chance that any rectifications are required, they are made in the DEV framework and transported to the QAS framework. Once the setup settings and ABAP programs pass testing in the QAS framework, all settings, projects, and changes are transported to the PROD framework, the framework that the organization uses to maintain its business forms.
