Specifies the codeunit that transfers external data in and out of the Data Exchange Framework.

After processing in the Reading/Writing Codeunit or the Reading/Writing XMLport, exported data is processed in the Ext. Data Handling Codeunit prior to being delivered to the external party. The format of the external data decides if processing occurs in the Reading/Writing Codeunit or the Reading/Writing XMLport.

After arriving from the external party, imported data is processed in the Ext. Data Handling Codeunit prior to processing in the Reading/Writing Codeunit or the Reading/Writing XMLport.

Note
The format of the external data decides if processing occurs in the Reading/Writing Codeunit or the Reading/Writing XMLport.

Exported data exits through the Reading/Writing XMLport prior to processing in the Ext. Data Handling Codeunit. Imported data enters through the Reading/Writing XMLport after processing in the Ext. Data Handling Codeunit.

For more information about the structure of objects in the Data Exchange Framework, see the diagrams in About the Data Exchange Framework.
