1. In CRM, you would click on the "+" tab.
  2. Then scroll down the page and click on "Relationship Codes".
  3. The View selection should default to "All"; click on it and select "All Relationship Codes" and then click go.
  4. You can create new one(s) or edit the existing ones there.
It's best practice to make any changes to Relationship codes in both systems FIMS and CRM.
