Document #

Document Number.

This field in the Open Item Maintenance window is the number that identifies this transaction.

This field is alphanumeric. You can enter up to six numbers and letters.

How Document Numbers Are Assigned

If you leave this blank when adding transactions, the system enters a six-digit document number for you.

For finance charges and balance forward (transaction type B) transactions, the system uses a special calculation based on the date and time that you run Report RAG (Aging Report).
For credit memos and charge invoices created in POS, the system uses the Next Invoice Number field in Function MIV (Modify Invoice Constants) to determine the document number.
For prepaids created in POS, and invoices, credit memos, and adjustments created in the Open Item Maintenance window, the system uses the Journal Number and Terminal fields in Function MTR (Modify Terminal Record). The first two characters of the document number (prefix) are based on the terminal number. The following table provides examples of this.

For Systems with terminal numbers 1-99, the following table applies:

If the terminal number is	Then the prefix is
01	A1
02	A2
11	B1
12	B2
21	C1
22	C2
31	D1
32	D2

For example:

Your terminal number is 11. The Journal Number field is 117. In Function MOI, you add an adjustment and leave the Document # field blank. When you press <Add>, the system enters B10117 in the Document # field. Since the terminal number is 11, the prefix is B1. The 117 comes from the Journal Number in Function MTR. The system adds a zero in front of the journal number to make the document number six characters long.

For Systems with terminal numbers 100 and greater, the following table applies:

If the Alternate Journal Number is	Then the Document number prefix is
000001-099999	A
100000-199999	B
200000-299999	C
300000-399999	D
400000-499999	E and so on.

How the System Handles Duplicate Invoice Numbers

The system's duplicate invoice number logic uses the letters listed below. If a duplicate invoice number is encountered, POS starts with K1 to K99999. If K if filled up, it then goes on to the other letters.
