Change ARFC2 Model RFC Destination at runtime

Hi All,

I am upgrading Web dynpro JAVA applciations from EP7.0 to EP7.31. I have a application which will connects at same time two ECC systems based on applciation platforms. With JCo destinations its working perfectly. now I have reimported Model and migrated to ARFC2 model and replaced Jco destinations with RFC destinations. I am passing same way the application parameters, But its not wsitching backend system.

Application URL:

https://host:port/webdynpro/resources/com.jnj.mercury/webuarinternalsarf/WebUarInternalSerApp?sap-wd-arfc-

useSys=WD_ECC_MODELDATA_DEST:RDV&sap-wd-arfc-useSys=WD_ECC_RFC_METADATA_DEST:RDV

I am following below help link and restarted my portal system also no luck.

• sap-wd-arfc-useSys

  • You use the parameter to map an existing logical system name to another logical system name. You can use this mapping function with a single Adaptive RFC Model to access different backend systems using a single JEE installation. This mapping is valid for the current application instance only.

  •   Note that mapping definitions can only be changed when WD application is not in running mode.
