To work, SEAzam receives the requested info and filters from a file or from a Web Service call. It answers a file or XML web service code.
When the job is a manual frontend activity, the 4 formats are available for import and export. The import format can be different from the export one.
When it’s scheduled, usually XLS isn’t possible because SAP needs to open an Excel session to generate the file and Excel isn’t installed on the SAP server.
When it’s a Web Service, XML is the standard format.
