Data types of sequential numbers

There are two data types of sequential numbers:

  • Simple numbers. For example, 1, 2, 3.
  • Complex character strings. For example, (DEV00001/WS).

Note: If you want to use the prefix and suffix capabilities of sequential numbering, the field being incremented or decremented must be defined in the database dictionary as type character. In all other cases, the field must be of type number.
