I'm being thick of course (though in mitigation I am new to FM9), but where/how/do I store primary key data so that if I need to change it, it changes are propagated to all of the tables in which I need it to appear. I think not changing it (i.e. using an auto-created serial number) is the best plan, but in any case I would still need to know how to get that auto-created serial number into the desired fields/tables. Any suggestions gratefully received. I've been reading "the only FM9 manual you will ever need" and it's like swimming uphill in treacle.
Cheers - in advance....
