While changing Assigned to field for Assets we get the error Asset 'Assigned to' is was cleared due to asset state changing.Summary<!-- /*NS Branding Styles*/ --> .ns-kb-css-body-editor-container { p { font-size: 12pt; font-family: Lato; color: var(--now-color--text-primary, #000000); } span { font-size: 12pt; font-family: Lato; color: var(--now-color--text-primary, #000000); } h2 { font-size: 24pt; font-family: Lato; color: var(--now-color--text-primary, black); } h3 { font-size: 18pt; font-family: Lato; color: var(--now-color--text-primary, black); } h4 { font-size: 14pt; font-family: Lato; color: var(--now-color--text-primary, black); } a { font-size: 12pt; font-family: Lato; color: var(--now-color--link-primary, #00718F); } a:hover { font-size: 12pt; color: var(--now-color--link-primary, #024F69); } a:target { font-size: 12pt; color: var(--now-color--link-primary, #032D42); } a:visited { font-size: 12pt; color: var(--now-color--link-primary, #00718f); } ul { font-size: 12pt; font-family: Lato; } li { font-size: 12pt; font-family: Lato; } img { display: ; max-width: ; width: ; height: ; } } The assigned to field does not get updated because of the below out of the box business rule set on asset table:Clear Assigned To on updatehttps://<instance-name>.service-now.com/sys_script.do?sys_id=594e2e93ef02200035c61ab995c0fb59The business rule will trigger whenever Assigned to value is present or is updated and State is 'On Order','In Stock' and 'In Transit'. In other words, if the State [install-status] of the asset is 'On Order','In Stock' and 'In Transit' it will not allow to update the 'Assigned to' field.A quick fix would be to set the State to anything other than 'On Order','In Stock' and 'In Transit', likewise, put the state of the asset to 'In maintenance' or 'In use' and change the 'Assigned to' field.
