Create an External Data Group
An SAP Gateway connection can be used in any Intrexx application. Find out here how and where you can create and configure a connection.
To integrate the connection into an application, select the application node and create a new external data group via the main menu "New / External Data Group. "
Enter the name of the new external data group, and then select the desired OData database connection. The appropriate data handler is then entered automatically.
You can enter the name of the desired table or view directly, or click "Search" at 
and search for the table or view name in the dialog box that appears.
You can find all additional information about the configuration here.
Files
Binary Data Fields
OData data fields of the type "Edm.Binary (BLOB)" are treated as the "File" data type in Intrexx. This allows binary data to be stored in Intrexx file fields. Since the file type cannot be automatically determined from OData binary fields, the file type can be specified in the data field's expert settings.
This is automatically used as the file name extension when saving the binary data. Currently, only one file type can be defined per field for all records.
Starting with version 2.0, OData provides so-called media link entries for accessing and manipulating files. These represent the recommended method for accessing binary data. Another way to make the contents of binary fields available for download is to call the callable method $ODataMediaResourceCallable.getDownloadURIForBinaryProperty(). This generates a URL that can be inserted into a download link on a view or input page:
<a target="_blank" href="$ODataMediaResourceCallable.getDownloadURIForBinaryProperty($ProcessingContext, $DC.getRecId(), '<GUID_DATENGRUPPE>', '<BINARY_PROPERTY NAME>', '<FILE_NAME>','CONTENT_TYPE', '<DISPOSITION_TYPE>')">Download File</a>
This method makes it possible to dynamically define the file name and content type by deriving these values from other fields.
