I guess the central question is how the base is supposed to ‘know’ employee names and their relationship to employee numbers.
If you had, for instance, a table containing these two fields —
{Employee Number}{Employee Name}
You could then link other tables to it based on the employee number and use a lookup field to retrieve the matching name.
If you’re trying to do this in a ‘flat’ base (one without links between tables), your only option would be to make {Employee Name}
a formula field and then create a multi-branched IF()
statement that explicitly linked numbers and names. The effort to create such a formula would be much greater than would be required simply to enter name and number manually.
I can think of a number of increasingly baroque alternative methods, but the real answer will depend on what you’re starting with: the source of the number and name.
