Hi Amith,
In this scenario, you can expire the SPL entry by changing Valid To date. Depending on customizing setting for legal regulation, these SPL records will not be considered in SPL screening but there is every chance that these are reactivated by next delta load of SPL files. If you are very sure about these customers, you can consider putting them in positive list.
On the other hand, system only archives the data which is marked for deletion.
regards,
Kul Vaibhav
