Hi Amit,

ModelData and Metadata destination while setting up JCo destinations are used for the following:

Modeldata is used for data retrieval (as in if you are searching for some values, the values that are retrieved as a result of the query is done using modeldata)

Metadata on the other hand is concerned with the Field/Table specifications(Its like data about data).

Hi Amit,

Dictionary metadata:

Contains the dictionary structure, that is the data about data

such as structures, data types which are used in the RFC

The connection is always Load-balanced since we need Logon group in R/3

And it needs Messageserver of R/3

Application data:

It retrievs the actual content of the RFC.

can be Load-balanced as well as Single server.

For e.g. We can say model data is the data coming through the table where as the metadata is the structure of table

For more information please refer to:

HI,

Model data gets you the application data for example if u search for a particular flight the model data destination is used to get the flights information.

meta data destination gets u the structure, data type and length for the data.

Hi,

One is for metadata and second is for modeldata.

Metadata contains the Structure.

Modeldata contains the actual data.
