The ABAP class CL_GUI_FRONTEND_SERVICES is quite a versatile tool that every SAP ABAP developer should know. It contains a lot of extremely helpful tools that help dealing with basic user interface requirements, such as showing confirmation dialogs, downloading data, or, obviously, taking screenshots.
Here is a short ABAP snippet that demonstrates how to save a screenshot in ABAP. While using the cl_gui_frontend_services=>get_screenshot method seems obvoius enough, knowing how to convert the raw image data into the SOLIX format is something that may require help. This code piece demonstrates how to do it.
DATA lv_imagebytes TYPE xstring. DATA lv_mimetype TYPE string. DATA lv_user_action TYPE i. DATA lv_file_name TYPE string. DATA lv_full_path TYPE string. DATA lv_filepath TYPE string. * Wrap everything in a try/catch block to capture exceptions TRY. * Capture a screenshot, using CL_GUI_FRONTEND_SERVICES * After this operation, lv_mimetype will contain the MIME type of the image, such as "image/jpg" cl_gui_frontend_services=>get_screenshot( IMPORTING mime_type_str = lv_mimetype image = lv_imagebytes ). * Show the default "save file" dialog cl_gui_frontend_services=>file_save_dialog( EXPORTING default_file_name = 'screenshot.jpg' default_extension = 'jpg' file_filter = '(*.jpg)|*.jpg|' CHANGING filename = lv_file_name path = lv_filepath fullpath = lv_full_path user_action = lv_user_action ). * Check if the user confirmed the dialog. * TODO: implement the cancel action. IF lv_user_action = cl_gui_frontend_services=>action_ok. * Create an internal table, converting the image bytestring to SOLIX. DATA(it_solix_data) = cl_bcs_convert=>xstring_to_solix( EXPORTING iv_xstring = lv_image_bytes ). * Download the screenshot to the user's file system. cl_gui_frontend_services=>gui_download( EXPORTING filename = lv_full_path filetype = 'BIN' bin_filesize = xstrlen(lv_image_bytes) CHANGING data_tab = it_solix_data ).
