How to fix deleted record.

Supriya25 — Sat, 24 Jan 2026 20:21:05 GMT

Hi All,

Kindly help me on below issue.

var gr = new GlideRecord("sys_history_line"); gr.addEncodedQuery("set=306b22cf93e676501a1bf6fa3d03d628^sys_idSTARTSWITH057ba2cf93e676501a1bf6fa3d03d656"); gr.query(); if (gr.next()) { gr.deleteRecord(); }

I have executed above code in background script. after deletion of history line I did check in Deleted record, delete recovery table , I didn't find any trace around sys_history_line record which I deleted from background script. how it is possible ?

when I did check sys_audit table, there I saw one record on 'sys_delete_recovery' exact time match with my script execution . how it is possible. I didn't touch "delete recovery "table.

now how can recover my 'history line'.

That table is managed by the instance, deleted records there won't work. And that table will be refreshed when any user access the record's history.

Open then record, for ex. incident record, then right-click on the header or the hamburger menu icon, select History from the menu, then List. History set and history line records will be generated from the sys_audit table.
