A business transaction can create one or more documents.
Documents in R/3 include a doc header and 2-999 line items.
A document remains a complete unit in the R/3 system until archived.
Controlling info may also be included in doc header
SAP records at least one doc for every biz transaction and each doc receives a unique doc number.
Every Doc uniquely identified by fol Fields:
i. Doc No
ii. Coy Code
iii. Fiscal Year
Two important control keys for documents are:
o Document Type (to control document header)
o Posting Keys (for line items)
Doc Type controls the doc header & is used to classify the business transactions to be posted, it is the key to
differentiate and classify business transactions.
Most imp control functions of doc types are ;
i. Number ranges for doc numbers;
ii. Account types permitted for postings
Doc Types defined at client level and valid for all coy codes. It controls the following:
i. which accounts to be posted
ii. number range
iii. field status of document header text and reference
iv. Whether invoices are posted with net procedure.
If no reversal document type is specified, the reversal doc has the same doc type as original doc.
You specify a number range for each doc type. However, you can use one number range for several doc
types.
You can copy the intervals of document number ranges from one coy code to another or copy intervals from
one fiscal year to other.
Every Coy Code may define its own Doc number ranges or doc number ranges created per coy code
Doc Number range can be internal or external. The internal range can be year specific or year independent.
Doc no ranges must never overlap.
External number ranges may be alphanumeric
System saves the last document used from number range in field Current number.
Doc number range must be defined for the year in which it is used.
i. Up to a future fiscal year :no restart
ii. For each fiscal year :restart
