1] Create a REST Message on source Instance and specify the Target instance Incident table URL and also create a Basic authentication type(:

2] Create a PUT (HTTP method), specify the target URL with a variable name as shown below. Payload is created in the BR itself. Create HTTP Headers as shown below and then click on Auto-generate variables:

Note: we require the sys_id of the target Incident record. We can fetch it using the GET method. Here I have parsed the response from the POST method: Click here
