I accidentally deleted the entry (coming from Device Manager/Automation Engine, to cut a merged flexo plate) in iPC, can I re-add it from within Device Manager/Automation Engine?
Yes, you should be able to re-Submit the file to Kongsberg Table (providing the original file was not (re)moved in the meantime).
If you work with Jobs, and the Submit to Kongsberg Table workflow/task is still in the Job's tasks, you can simply relaunch the workflow/task.
If you don't work with Jobs, but know the time when the original Submit to Kongsberg Table workflow/task was executed (i.e. when the cutting file was originally submit/copied), you may also be able to locate it in the tasks, and you can simply relaunch the workflow/task.
If you don't know which is the Submit to Kongsberg Table workflow/task, you'll have to find out the name of the input XML.
If you don't know which Merged Plate exactly it was, go find it in Press Plate Sets View (at the bottom of the right pane) or in Press Plates View (right click the Press Plate > Go to Merged Plate)
In Merged Plate View, note the name of the Merged Plate (mergedplatename.par):
Browse (using an OS file browser might be most convenient) to the Plate Merger output folder. If you don't know it, you can find it back under Tools > Configure > Plate Merger > Output Folder):
Search for the mergedplatename(.par) in the subfolders of the Output Folder.
Once you know the exact subfolder, browse to it in the Pilot. Select the cuttingrequest_datetime.xml file, and launch the Workflow used to submit the cutting requests to the Kongsberg Table. (If you are unsure which workflow this is, you can find it back under Tools > Configure > Plate Merger > Cutting Workflow)
