Hi kaur,

Do you have assessment admin role. In that table write operation for those role only, based on acl only we can access the data.

even try one more,

var gr = new GlideRecord('asmt_m2m_category_assessment');

gr.initialize();

gr.assessment_record = current.vendor;

gr.category = current.u_it_resource_subtower;

                              gs.addInfoMessage(gr.assessment_record);

                              gs.addInfoMessage(gr.category);

var sysId= gr.insert();

gs.addInfoMessage('AssignGrp:'+gr.assessment_record+' ,category:'+gr.category+' ,sys_id:'+sysId); // check it shows sys_id or not

if not try to trigger same business rule with, assessment_admin role user by impersonating some one.

please let me know what are all the results do you get.

you mentioned only create and read acl on that table. If there is read acl defined means all users having read access.
