Okay, so this is the issue. You can see DESADV.DELVRY03 (Sender Interface) SWCV is showing some ID. That means the reference is missing. You may not have any SWCV named <SAP APPL 6.0*>. Just like I asked earlier,
Click 'Find' option
Search with string "DESADV.DELVRY03" and please provide me the screenshot of the IDocs what you can see. and if you find my posts helpful, you can always reward with points.
