ABAP performance improvment

When you delete an entry from an internal table in ABAP, the system has to re-generate the index.

When you delete an entry from an internal table in ABAP, the system has to re-generate the index for all entries after your delete, slowing the report if you have many records to eliminate.

It is much quicker to do an insert of the correct records into a second table than to delete entries from the first. The reason for this is because the index is only generated for the newest element.
