With the help of background scripts management processes and other time-consuming manual processes can be automated.
An example of a background script that automated an administrative process, is ‘BUBS_EMPTY_INTERFACES’. With this script the contents of the ERP interface tables are removed.
If a background script requires parameters for processing they can be specified in the part of the screen with the name ‘Script Parameters’.
The registration of background scripts is a typical activity for application developers. See the warning under Application Development.
