You can perform varying degrees of customization on the data that comes from the SAP back end.
There are several levels of customization of the original SAP data structure.
| Customization | Tasks to Implement | Tasks to Upgrade |
|---|---|---|
| None. | Download the ESDMA bundle and deploy it on Unwired Server. | Subscribe a new device and start using the application. |
| Change the distribution pattern. | Change the distribution pattern,before or after downloading ESDMA bundle. | Unsubscribe and resubscribe old devices. |
| Add code-free extensions. | Add custom fields to dummy nodes on the SAP back end. Include code in the application to manage the dummy fields. | None; users continue using the application without interruption. |
| Change the data model. | Release the SWCV for shipment, then change the data object, enhance and regenerate the back-end adapter, and generate and download the ESDMA. | Generate a new application with a new ESDMA and deploy to Unwired Server in a new domain. Continue running both old and new applications in different domains and let users decide when to move to the new application in the new domain. |
