I have an Enquiry Number field in the deal( enquiries ) module and have quote related list so when I add/assign a new quote to deal(enquiry )enquiry number field value should be updated in the Enquiry number field of the quote module.
I have a Subscription to the professional plan so can't use the custom function for this. also tried to update by ${Quotes.Enquiry Name.Enquiry_Number} but it's not workable.
