Order Import - Corrections Window missing errors after some time

Hello,

We are Importing Sales Order THROUGH the open Interface tables ORDER_HEADERS_IFACE_ALL and OE_LINES_IFACE_ALL. Once we get the data to the import tables OE_HEADERS_IFACE_ALL and OE_LINES_IFACE_ALL we run the standard Order IMPORT concurrent program to import sales order. We are successfully importing all the orders.

Problem: When we run the Standard Order Import Process and then if the process Errors out, we can see the errors in the Correction Window( OrderManagement>Import Orders>Corrections). After few hours the errors are not available in the ERRORS Correction Window. Can I know what could the issue that is removing the errors from Errors correction window after few hours?
