I am trying to create a rule that will create a CTA and assign it to the BDR on my account. When clicking on the Owner Field in the rule I do not have any options populating there to auto assign this CTA to. I know the only options shown in this field are user lookup fields related to the account or customer info object. Since I am using a Data Space I created I can't seem to add the correct field to that data space that will populate the user field in the Owner Field area on the rule. How do I know which fields to choose out of all my options? Are there limits to what can be added to a Data Space that may be preventing me from getting the correct field? See attached a screenshot of my data space.
