Key formats and counters fields
The relevant table (or document) on which you want to change the setting.
Indicate the mask here, or how the primary keys of the document should look like. The letter before @ sign indicates how the sequence number should begin. The number after the @ sign indicates how many digits the sequence number must consist of.
This is the counter reading of the sequence number. At the start of RentMagic, the counter may be at 0.
