I developed a report for uploading files like .xslx and .csv it's working fine. For uploading i use function modules ' TEXT_CONVERT_XLS_TO_SAP ' and 'GUI_UPLOAD'. The same added to poratal. While running from portal side it's going to dump 'JAVABEANS NOT SUPPORTED'. I already found some post in sdn but i can not understand those one's . I am new to this. Please help me.
