Loading, Displaying, and Deleting Metadata

IDoc (intermediate document) metadata comprises structures for the corresponding IDoc types that are required by the IDoc adapter to convert these IDocs to IDoc XML format and the other way around.

Using an RFC connection, metadata of this type can be either called directly at runtime or uploaded to the Integration Server beforehand.

The system where the metadata is located is either the sender or receiver SAP system, or the SAP reference system where the metadata is saved if the sender or receiver system is a subsystem.

You can display metadata that has already been loaded, or if you are upgrading the application system then you can delete the metadata and reload it.

To access the metadata in the sender system, you must establish an RFC connection to this system using the port maintenance in the IDoc adapter.

1. To find out what metadata has already been loaded, call transaction Metadata Overview for IDoc Adapter (IDX2).

   The system displays a screen with the directory of all systems connected with the IDoc adapter (including a description) for which metadata has already been loaded. Choose Port Maintenance in IDoc Adapter () to go to the corresponding transaction and to create additional ports.

2. To display the IDoc types and clients including a description for each system, expand the individual systems.

   The system displays the metadata for each connected system for which metadata has already been loaded.

3. To copy the metadata structure loaded from a particular system to another system (for example, to an SAP reference system), choose the link to the corresponding IDoc type and choose Copy ().

   The system displays a dialog box in which you can copy the IDoc type description to another system (Target Port).

4. To delete metadata that has already been loaded, select the link to the corresponding IDoc type and choose Delete ().
5. To load additional metadata, choose Create ().

   The system displays a dialog box where you can enter the IDoc type including the extension, and the system (Source Port).

6. Make the required entries and choose Continue.

   The new structure is inserted in the tree structure as follows:

   • If the structure originates from a system from which metadata has already been loaded, it is inserted below the structures already loaded from this system.
   • If the structure originates from a system from which no metadata has already been loaded, it is inserted together with the system below the already listed systems.
7. To display details about a metadata structure that has already been loaded, choose the link to the corresponding IDoc type. To display this structure in detail, choose Display (). The system displays the structure in a hierarchy tree.
8. To display the corresponding system (port) and the basis type from the detailed display, choose Header Information ().
9. To display the segment versions of all segment types contained in the structure, choose All Segment Versions ().
10. Select a segment to display all its fields.
