Understanding Purging Interoperability Transactions
When data becomes obsolete or you need more disk space, you can use a purge program to remove data from interface files, in this case test results transactions.
For records in the Processing Log table (F0046) that are marked as processed, the program purges the associated transactions in the corresponding interoperability tables, as well as the records in the F0046 table. If the records in the F0046 table are not marked as processed, the program does not purge any records.
