Below is a sample example using Business Rule which prevents the deletion of attachment when Incident record belongs to a certain 'group': ============================================================================================= - run on Table = Attachment [sys_attachment] - Advanced = checked (true) - When = before - Delete (checkbox) = checked (true) - Filter conditions = table name | is | (example = incident) - Sample script:

(function executeRule(current, previous /*null when async*/) {

var tableName = new GlideRecord(current.table_name); //incident tableName.addQuery('sys_id', current.table_sys_id); //incident record sys_id tableName.query();

if ( tableName.next() ) {

if ( tableName.assignment_group == 'SYS_ID_OF_THE_GROUP' ) { current.setAbortAction(true); // if condition matches, abort deletion } }

})(current, previous);

Below is an alternate method using 'delete' operation ACL which controls the deletion when Incident record belongs to a certain 'group': ========================================================================================== - Type = record - Operation = delete - Name = Attachment [sys_attachment] - Advanced = checked (true) - Condition = table name | is | (example = incident) - Sample script:

answer = getAnswer();

function getAnswer() {

var tableName = new GlideRecord(current.table_name); tableName.addQuery('sys_id', current.table_sys_id); tableName.query();

if (tableName.next()) { if ( tableName.assignment_group == 'SYS_ID_OF_THE_GROUP' ) { return false; // condition matches, don't allow deletion }

else { return true; //condition doesn't match, allow deletion } } } Please note, if you apply the above ACL, you may need to add the below additional condition in the OOB ACL with sys-id = "0c66472a0a0a0b82017c1f3df66a3fe7" >> - include additional Condition = table name | is not | - direct url: https://instance_name.service-now.com/nav_to.do?uri=sys_security_acl.do?sys_id=0c66472a0a0a0b82017c1f3df66a3fe7

Please review them and thoroughly test in your sub-prod instance(s) before you apply in your Production based on your requirements. Furthermore, customisations made to the out-of-the-box (OOB) product are not covered by Technical Support, so customers will need to ensure compatibility with future ServiceNow releases and patches.
