Components of the Official Document Number 
Components of the Official Document Number
An official document number is required by Argentine law.
The official document number consists of four components. The capital letter, issuing branch and sequential number are stored together in the reference document number. The official document class is assigned internally to the document.
The capital letter classifies the document according to business partners and business transaction. It is determined by the fiscal type of the issuing company, the fiscal type of the customer and the kind of transaction for invoices and credit memos. Please have a look at the Determine capital letter customizing. For waybills the capital letter is fixed to the value ‘X’. For documents not acting as waybills it is possible to change the determined capital letter as long as the document is not numbered officially. This is done in the header section of the documents.
The fiscal type - as a base for the determination of the capital letter - has to be maintained for the company and for the customer. The fiscal type for the company has to be maintained in the company code master data. You will find further details in
We strongly recommend setting the field ‘Fiscal type’ in the master data to ‘Entry required’. This is also required for CPD-customers and vendors.
An issuing branch is a kind of ‘physical issuing location’ for the document. This could be a department, an invoice office, the desk where the document is printed, the printer, etc.
In the SD and MM modules, the issuing branch is determined automatically by assigning it to organizational units. For billing documents the issuing branch is determined via the sales area, for delivery notes via the shipping point. For material movements acting as the base for a waybill the issuing branch is determined via the combination of plant and storage location. In the FI module the issuing branch must be entered manually.
It is important that the assignments for the issuing branches are maintained for all possible constellations.
Whenever the issuing branch is not filled, a warning appears during the document entry. The issuing branch can then be maintained on document header level, this is also the place for individual changes. Once the document is officially numbered it is not possible to change the issuing branch anymore.
This is a sequential number that is determined automatically according to the different combinations of document class, capital letter and subsidiary number. For financial documents the chronological order of the numbers could be checked in the system. If this check is activated you will not be able to post a document with a document date prior to the last assigned document date.
This number is generated when the document is created and can not be changed afterwards, except for delivery notes where it is possible to specify the point in time when the numbering takes place in more detail.
Argentine law requires the assignment of an official document class. The following values are delivered by SAP:
The document class classifies documents according to Argentine statutory requirements. It is used to distinguish the official document (e.g. invoices and payments) according to the numbering requirements. Additional document classes can be defined in the system.
The document class is assigned to the corresponding entities in the applications:
Whenever there is no document class assigned the corresponding operation/transaction is considered to be not relevant for the official Argentine document numbering.
