Post processing of defect records from automatic Goods movement

During the run of COGI transaction, we got the List of all goods movements with errors.The list of errors can be <b>saved at once</b> and the other option is <b>save for background</b> (when we choose option List -> Save -> Save at once or Save for Background).In save at once option it saves the error & save for background shows the message "goods movements were entered as a background job".

Now my question is 1)What is the use of Save for BAckground? 2)If there are are multiple errors for a single raw material (say 7 errors)associated with different Process orders in COGI output.When we choose two or more error(say five errors we selected check boxes) the exercised option <b>save for background</b> the displayed message is self explainatory & it should have created a background job.But when I checked the SM37 (Simple Job Selection) it did not show us the Background Job details.

3)When I exercised the option of <b>Save for Background</b> & processed five error records, how can I find which I processed & where they gone?
