Generation Source

Generation Source for the Reference Number Qualifier can be one of the following:

Manual – Fixed Length (MANUAL)
Internally Generated (INTERNAL)
Transaction Generated (TRANSID)
Manual – Free Format (FREE_FMT)

The following table describes compatible values and their associated meanings:

	Generation Source	Auto Generate Only	Sequence ID	Literal (*)	Start/ End Position Free Format	Start Position for Sequence	Check Digit
1	MANUAL	FALSE (view only)	Null	Required	Required		Null
2	FREE_FMT	FALSE (view only)	Null				Null
3	TRANSID	TRUE (view only)	Null		Null		Null
4	INTERNAL	TRUE (default) / FALSE	Required	Required	Null	Required (**)	Optional

Notes:

(*) Leading spaces not allowed
(**) checks the Literal Length & Start position vs. the Length of the Sequence

User Defined vs. System Defined

In cases 1 and 2 above, the Reference Number will be user defined only.
In case 3, the Reference Number will be system defined exclusively.
In case 4, the Reference Number will be generated by the system but it can be overridden by User if the Auto-Generate Only flag is False.

Length

In cases 1 and 4, the length is internally set based on the number of non-null characters in the Literal.
In case 2, the length is not defined. Any number of characters are accepted up to the maximum size for the reference number column.
In case 3, the length is internally set to 30.

Internally generated reference numbers will support a fixed length format with user-specified literal strings, a single embedded ranged sequence and a single check digit (for example, Modulus 10, Modulus 11).

Some of the Generation Sources are only supported for certain Reference Number Types:
