BELOW DOESNT REALLY WORK BUT ILLUSTRATES A POSSIBILITY

see my post "prevent high volume spam api calls on task table: my version for Incident table" for a version I got working

on insert business rule: one option

(function executeRule(current, previous /*null when async*/) { var thresholdPeriod = parseInt(gs.getProperty('x_moju2_siam_integ.threshold.period') * 60); //minutes to secondsvar maxTransactions = parseInt(gs.getProperty('x_moju2_siam_integ.threshold.value')); var dateBack = new GlideDateTime(); dateBack.addSeconds(-thresholdPeriod); var date = dateBack.getDate(); var time = dateBack.getTime().getByFormat('hh:mm:ss'); var qryStr = "sys_created_onBETWEENjavascript:gs.dateGenerate(" +"'"+ date +"'" + "," + "'"+ time + "'"+ ")@javascript:gs.endOfCurrentMinute()"; var gr = new GlideAggregate('x_moju2_siam_integ_transactions'); gr.addEncodedQuery(qryStr); gr.addQuery('sys_created_by', gs.getUserName()); gr.addAggregate('COUNT'); gr.query(); var count = 0; if (gr.next()) count = parseInt(gr.getAggregate('COUNT')); if (count >= maxTransactions) { gs.error("SIAM - Number of permitted Transactions per " + thresholdPeriod + " minutes has been exceeded for interface: " + current.messageid.getDisplayValue() + ".New transaction inserts not permitted for this interface "); current.setAbortAction(true); } })(current, previous);

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 ); }
