Transform maps: store an error value in a session object, to pass from one transform map to another

transform map 1: we want to flag an issue to pass to transform map 2, which has its order set to a higher order so it runs after transform 1 (both fire off the same import set)


var session = gs.getSession();

var sSessionErr='no_errors';
if (bIgnore){ //set higher up in the script somewhere to flag an issue
    sSessionErr='an error -- text';
    response.error_string_inc=sSessionErr; //--if stuck in the old world of SOAP as opposed rest, can alter the response [web service transform maps only]...
    gs.log(sSessionErr, 'inc_transf_1');
    ignore=true; //this transform will ignore
}
session.putClientData('tmap_xyz_Errs', sSessionErr);



transform map 2: grab the error session string and alter the logic if it's present:
var incTransfErrs = session.getClientData('tmap_xyz_Errs');
if (incTransfErrs=='no_errors'){
        response.mab_error_string_task='';
}else{
    gs.log(sSessionErr, 'inc_transf_2');
    ignore=true; //this transform will also ignore
}
//--final clear down of the error session data as not needed for the transaction beyond this point:

session.clearClientData('tmap_xyz_Errs');


(for import sets with lots of parallel runs, consider adding something unique to the session token to make sure it's unique for that particular row being processed, append the ticket number to the session name string or something similar)

Get URL Parameter - server side script (portal or classic UI)

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 ); }

ServiceNow check for null or nil or empty (or not)

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 )){
