Hello,

It seems that two way syncing between CRM and Books isn't allowed if you attempt to sync CRM fields that are the result of a formula.

It makes sense why this needs special consideration since there's no practical way for CRM to derive the formula's input from based on what would normally be the formula's output if it should be updated within Books.

I think however that disallowing two-way syncing entirely for all fields of a particular type (e.g. Contacts) is an unnecessary limitation.  Why not simply make note beneath any formula based fields that they'll only update in one direction from CRM?  That way you're neither preventing their use, nor preventing 2 way syncing of all the other fields.  Couldn't the system just block formula based fields from syncing back to CRM and leave the others to sync both ways.

Thanks,

Bryan
