The SCTID data type is a 64-bit positive integer.

When rendered as a string an SCTID must always be represented using decimal digits and when rendered as a string has a maximum permitted length of 18 digits and a minimum length of 6 digits.

Note: Leading zeros are always omitted from the string rendering of an SCTID. For example the value "101291009" must not be rendered as "0101291009".
