Refreshing Your Field Info
If you create a new field inside of one of your systems and don't see it in the available mappings in Bedrock Data. You are going to want to refresh your mappings page to populate those new fields in Bedrock Data (please see image below).
Also if you make any changes to your Bedrock Data settings, mappings, workflows, etc. It is best practice to refresh the field info so the new changes will be reflected for future syncs.
