Do we lose the transaction information and drill down from journal after 90 days?

Summary:

Hi Experts,

FAH standard functionality says any transaction that is finally accounted and posted in GL will be deleted after 90 days (default) which can be extended to 456 days. I am having hard time understanding this feature, does this mean we cannot access the transaction anymore from Manage Subledger Journals or from Manage Journals and drill down to transaction? Do we lose the transaction as well as drill down functionality completely? or is it just the file used to upload the transaction is deleted?

If the transaction is completely lost, what happens when we click on View Transaction from the journal and what if we built reports using the FAH transaction objects?
