Each vendor can be assigned to a specific accounts payable sub-ledger for situations where you wish to track your payables in the general ledger based on vendor type. If you are using this feature (it is an optional feature), the appropriate accounts payable autopost number should be specified for each vendor during setup (a generic code table is also normally used to validate this field when this feature is implemented).
If you will be using more than 1 accounts payable control account in the general ledger you should create a generic code table to indicate what each AP control account is used for. This will indicate which vendors are included in each control account. This table will be used to validate the AP account used for each vendor (to ensure the field is loaded and that it contains valid information) during setup and maintenance.
The Gencode table that controls the AP_ACCOUNT field in the vendor file is named F80:101 This table is normally named the Vendor AP Autopost Table and the records in this table are normally loaded with the accounts payable control account autopost number (a value from 310-319), and a description of what the account is used for (“third party”, “group company”, and “holding company” are examples).
If you are using only one accounts payable control account, you should assign the GL account an autopost of 310 (the default) and you should not need to load the AP_ACCOUNT field in the vendor records or create the above Gencode table.
