Do Not Target System Fields (sys_created_on, sys_domain etc) in Field Maps in Transform MapsDescriptionWhen using a Transform Map to import data from a source table (e.g. u_imp_user) to a target table (e.g. sys_user) it is generally not supported to target system fields (those beginning with sys_) on the target table. Release or EnvironmentAll ServiceNow ReleasesCauseCustomers have had unexpected results with Field Maps that target the Created or Updated On/By fields (sys_created_on, sys_created_by, sys_updated_on, sys_updated_by) or the Domain (sys_domain) field. Updating these fields on a target record by using a Field Map will get unexpected results and should be avoided.ResolutionCreated or Updated On/By fields (sys_created_on, sys_created_by, sys_updated_on, sys_updated_by): If you really need to change the value of any of the date fields you can do an XML import. To get the correct format of the XML file you'd need to do an XML export of an example record first. (This only applies to instances with Domain Separation enabled) Domain (sys_domain) field: You should run the import as a user who is in the same Domain that you want the imported data to be in.
