There are six possible document types. They are:
Invoice— Normally created at POS, when a sale is charged to a customer account. Can also be added in Open Item Maintenance (MOI).
Credit— Normally created at POS, when a credit memo is charged to a customer account. Can also be added in Open Item Maintenance (MOI).
Adjustment— Created in Open Item Maintenance (MOI) only. An adjustment can be for positive or negative amount (debit or credit).
Finance Charge— Created by running Report RAG. Finance charges are calculated based on the options you set in Function MCT (A/R Control File Maintenance) and the closing date entered on Report RAG.
Payment— Generated at POS or through Received On Account (ROA) when a charge customer pays off all or a portion of the running balance.
Balance Forward— Created by running Report RAG with Option P. All past due transactions are compressed into a single balance forward document and the individual transactions are deleted. Balance forward documents are created only for Revolving Charge and Balance Forward accounts, not Open Item accounts. Options for creating this document type are set up in Function MCT (A/R Control File Maintenance).
