Issue:
Request regarding the deletion of records on the following tables
- azure_billing_daily
- azure_billing_monthly
Business Impact:
Tables have not been used since 2018
Solution Proposed:
This is a common question regarding data management. We have an article which
provides several methods to handle the data and possible deletions:
https://support.servicenow.com/kb?id=kb_article_view&sys_kb_id=fbc46dd2db266010c9c302d5ca9619a5
The article covers the following four topics:
UI actions
Clone exclude rules
Table cleanup policies
JavaScript
We recommend testing in subproduction environment(s) prior to any implementation in production. ServiceNow does not intervene in data removal requests unless the presence of those records are causing a business critical operation to be unusable.
Next Steps:
Would you be able to review the cleanup methods mentioned and let us know if you have any additional questions. We would be happy to follow up.

example script - tables no longer used:
var grBusRule = new GlideRecord('sys_script');
grBusRule.addActiveQuery();
grBusRule.addQuery('name', 'custom-Azure Billing Query Based On Role');
grBusRule.query();
if (grBusRule.next()) {
gs.log('PLEASE DISABLE BUSINESS RULE "custom-Azure Billing Query Based On Roles" BEFORE PROCEEDING', 'fixScr_16482');
} else {
var stable1 = "azure_billing_daily"; //--4M +records
var stable2 = "cloud_mgmt_billing_daily"; //--2.5M +records
var stable3 = "cloud_mgmt_tag_history_map"; //--874K +records
var stable4 = "cloud_mgmt_rsrc_tag_history"; //--226K+ records
var stable5 = "azure_billing_monthly"; //--156K +records
truncateAzureTable(stable1); //--timing: took approx 40 mins for the largest table
/*truncateAzureTable(stable2);
truncateAzureTable(stable3);
truncateAzureTable(stable4);
truncateAzureTable(stable5);*/
}
function truncateAzureTable(tableName) {
var bTruncate = false;
bTruncate = true;
var Tgr = new GlideRecord(tableName);
Tgr.query();
if (bTruncate) {
gs.log(tableName + ':: table truncate START', 'fixScr_16482');
/*skip business rules*/
Tgr.autoSysFields(false); //--leave last updated intact
Tgr.setWorkflow(false); //--skip business rules and notifications
Tgr.deleteMultiple();
gs.log(tableName + ':: table truncate END', 'fixScr_16482');
} else {
gs.print(tableName + '--TABLE ROW COUNT: ' + Tgr.getRowCount());
}
}
