To ensure that the data being shared out of Cherwell and into ServiceNow (inbound data) is being mapped correctly when arriving at your ServiceNow instance, you will next need to add and update some of the scripts in the **PSP Common Incident to Incident** transform map under the PSP Common Transform Maps module. [ServiceNow transform maps](https://docs.servicenow.com/bundle/madrid-platform-administration/page/script/server-scripting/concept/c_CreatingNewTransformMaps.html) handle the format of data being shared into a ServiceNow instance. Making changes to the transform map scripts will allow data to be properly shared out of Cherwell and then be mapped correctly to the relevant fields in ServiceNow.
