Helper Vcalculating a value based on other column
I have the following data
a ticketnumber has an id in the ticketdetails table. This id is linked with the table tickets. A ticket has a majorticketid, or is blank (when there is no major ticket assigned).
When there is a majorticket assigned, this also has a ticketnumber in the table ticketdetails.
Now i need to be able to create a column ticketdetails table, that basically says;
when ticket.majorticketid is not empty then ticketdetailsticketnumber, otherwise blank
both tables are linked via ticketid, one on one relationship.

TechR21 , In the tickets table , assuming both are joined
maxx(relatedtable(ticketdetails),[ticketdetailsticketnumber])
else add filter
maxx(filter(ticketdetails,ticketdetails[ticket id] = tickets[ticket id]) , ticketdetails[ticketdetailsticketnumber])
