Hi,

When JCO connection is done, you can get the backend data to portal or webdynpro application. Metadata is some data about the backend table information like structure of table, no. of fields etc. Metadata helps in retrieving the structure and classes from backend tables while model data carries the actual data or value.

hi

Rfc metadata and modeldata logical system destnations to connect to backend systems used in configuration of JCOs .

we configure JCOs in ContentAdmin.

Meta data is the Dictionary data thats why you find Metadata destination in Dictionaries of your project.

Modeldata is the Application data,you can find logical system name of Modeldata in Properties of your Modelclass.

So Model data destination will fetch actual data while metadata destination will contain description of the data.

Hi Sowmya,

How do I check logical system name of model data? You have said properties of model class but I couldn't find any logical system name in properties of model class.

HI

Rightclick on any any model class.(Input or output) and click on EDIT button.

at the rightside(down) properties window will be displayed.

There you can find Modeldata destination name.
