Hello,
The following link http://help.sap.com/saphelp_nw04/helpdata/en/af/84a34098022a54e10000000a1550b0/content.htm talks about the support to map multiple backend systems by specifying the backend system as URL parameters in a webdynpro application.
For example:
http://<hostname>:<port>/webdynpro/dispatcher/local/ESSProject/ESSApp?
sap.wdarfc.useSys=WD_MODELDATA_DEST:ABC&
sap.wdarfc.useSys=WD_RFC_METADATA_DEST:ABC
Is it possible to programmatically change the backend systems the application connects to? in other words can a single application while executing connect to different backend systems by dynamically changing the model parameters?
(This should be possible without the portal in the picture)
Cheers,
Praveen
