Hi,

the metedate will not be refreshed when you import a new model, ARFC will also have the same metadata, when we restart the j2ee engine then every thing will be refreshed.

Hi Ishita

It is recommended to restart the J2EE Engine after reimporintg the model because metadata will not be refreshed,

The Web Dynpro Adaptive RFC framework sits on the top of several layers such as the Java Connector Objects (JCO), Data Dictionary (DDIC) and the MDI.

After the first access each of these layers caches the metadata within them and keeps returning the cached values thereafter. The caches are not refreshed even if something would have changed in the metadata on the R/3 backend. In addition the Web Dynpro ARFC model itself also caches the metadata. The new invalidation tool will try to refreshes the caches across all the layers. The earlier solution to refresh the caches was to simply restart the engine.

Please look into this Blog, [reimporting a Model without restarting|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/10465350-b4f5-2910-61ba-a58282b3b6df] the J2EE Engine.
