How do I manage a composite key (string + numbers)?
For example, you could create a primary key composed of five characters followed by four figures.

At the table level, create a field of type VARCHAR, length 9, as a primary key.


 * On the creation form use the control "Masked field" with the properties:
 * Input mask: AAAAANNNN
 * Validate input: Yes

With this setup, only valid characters are accepted.
