UI Action conditions:

'create incident' button

add this to the condition field:

&& (new InteractionUtils().intHasRelatedInc(current.sys_id) == 'false')

'create request' button

add this to the condition field:

&& (new InteractionUtils().intHasRelatedReq(current.sys_id) == 'false')

'create case' button

add this to the condition field:

&& (new InteractionUtils().intHasRelatedCase(current.sys_id) == 'false')

script include "InteractionUtils" functions:

intHasRelatedInc: function(current_sys_id) { var table_name = 'incident'; var field_name = 'u_interaction'; if (current_sys_id == undefined) current_sys_id = this.getParameter('sysparm_current_sys_id'); var record = this.getGlideRecord(table_name, field_name, current_sys_id); if (record == null) return 'false'; return 'true'; }, intHasRelatedReq: function(current_sys_id) { var table_name = 'sc_request'; var field_name = 'parent_interaction'; if (current_sys_id == undefined) current_sys_id = this.getParameter('sysparm_current_sys_id'); var record = this.getGlideRecord(table_name, field_name, current_sys_id); if (record == null) return 'false'; return 'true'; },

intHasRelatedCase: function(current_sys_id) { var table_name = 'interaction_related_record'; var rel_rec_table_name = 'sn_customerservice_case'; if (current_sys_id == undefined) current_sys_id = this.getParameter('sysparm_current_sys_id'); var record = new GlideRecord(table_name); record.addQuery('interaction', current_sys_id); record.addQuery('document_table', rel_rec_table_name); record.query(); if (record.hasNext()) return 'true'; return 'false'; },

getGlideRecord: function(table_name, field_name, field_value) { // Returns a glide record object, which has a specified value in a specified field. if (field_name == undefined) field_name = this.getParameter('sysparm_field_name'); if (field_value == undefined) field_value = this.getParameter('sysparm_user_value'); var user = new GlideRecord(table_name); user.addQuery(field_name, field_value); user.query(); if (user.next()) return user; return null; },

Haven't tested these all recently within global/local scopes, so feel free to have a play! option 1 use an encoded query embedded in the GlideRecord , e.g. var grProf = new GlideRecord ( 'x_cls_clear_skye_i_profile' ); grProf . addQuery ( 'status=1^ owner=NULL ' ); grProf . query (); even better use the glideRecord addNotNullQuery or addNullQuery option 2 JSUtil.nil / notNil (this might be the most powerful. See this link ) example: if ( current . operation () == 'insert' && JSUtil . notNil ( current . parent ) && ! current . work_effort . nil ()) option 3 there might be times when you need to get inside the GlideRecord and perform the check there, for example if the code goes down 2 optional routes depending on null / not null can use gs.nil : var grAppr = new GlideRecord ( 'sysapproval_approver' ); var grUser = new GlideRecord ( 'sys_user' ); if ( grUser . get ( 'sys_id' , current . approver )){

Classic UI : var sURL_editparam = gs . action . getGlideURI (). getMap (). get ( ' sysparm_aparameter ' ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); } Portal : var sURL_editparam = $sp . getParameter ( " sysparm_aparameter " ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); }
