The following is an example of updating a Credit Memo where we are changing some of the fields. (See [Credit Memo](docId\:rOGVPWAviJlOdMLuJjwd5) for all available fields).  The NetSuite Credit Memo Id (internalId) is required to update the Credit Memo.

Note: You can only update one record at a time

The response returns the complete Credit Memo information, but we have shortened the response in our example for ease of reading.
