| After you create a software environment, you must fill the environment with software components. In a single-system environment, you can copy the software components from another environment to your new environment. In a multisystem environment, you can use ERP LN ’s export/import tool. Copy software components concept You can copy software components from one software environment to another. For example, you can customize software components in a dedicated development environment and then copy the components to a new run-time environment or to an environment that is already in use. If you copy the software components into another environment, you must compile the components in the new environment and then convert the components to the new environment’s run-time data dictionary. The result of this example is that normal users can use the released software components without the need to create new package VRCs or package combinations. Developers can continue to create customizations on the standard software components in their dedicated development VRC. The components that are copied into a new runtime environment are positioned at a higher level. For example, components that are copied from the package VRC tfB60O_b1 into the new run-time environment are placed in the package VRC tfB60O_b2. For more information, refer to the Copy software components procedure. Export/import software components concept With the import/export procedure, the software components of a package VRC are exported to sequential files and imported into a package VRC of another environment. If you have imported the software components into another environment, you must convert them to the run-time data dictionary of the new environment. The following figure shows an example of the export/import procedure: Example of the export/import procedure Use the export/import method to fill an environment in a multisystem environment. The sequential files that contain the exported software components are sent from one system to another by means of File Transfer Protocol (FTP), a CD-ROM or by e-mail. The following figure shows the import/ export concept in a multi-system environment: Import/export procedure in a multi-system environment FTP is a protocol used to copy files to and from remote computer systems on a network using TCP/IP, such as the Internet. This protocol also enables you to use FTP commands to work with files, such as listing files and directories on the remote system. For more information, refer to the Export and import procedure. |
