IDoc Interface: Invoice Receipt to Accounting 
Transferring Data from Logistics of an External System
The SAP R/3 Accounting components can import data from invoice receipts posted in external logistic systems. The FI/CO interface inbound IDoc ACLPAY01 is used for this ( IDoc Interfaces for Data Transfer to Accounting ).
Example
Raw materials are sold on credit and the invoice receipt is posted in an external logistic system. The FI/CO interface transfers the data relevant to accounting to the Accounting application components.
400100 Raw Material Purchase to 160000 Vendor Payables $100,000
154000 Input Tax to 160000 Vendor Payables $15,000
Transferring Data to Accounting of an External System
To transfer invoice receipt data from an SAP R/3 Logistics system to an external Accounting system, you use outbound IDoc ACLPAY01.
BODs
IDoc ACLPAY01 fulfills the Open Application Group (OAG) communication structure for the Business Object Documents (BODs) Load Payable (invoice receipt) and Confirm for the transfer of an invoice receipt to an accounting system.
The outbound IDoc for Logistics can be transferred to the BOD structure. SAP does not convert IDocs into BODs; certified EDI and ALE partners provide this service.
The inbound IDoc in Accounting can be provided with data via the BODs.
Preconditions and Requirements
Synchronization of the outbound and inbound systems is mandatory; the same account assignment objects must exist in both systems during the data transfer.
Structure of IDoc ACLPAY01
The structure of the IDoc ACLPAY01 and its documentation is defined in the SAP R/3 System. To display these, proceed as described in Displaying IDoc Type and Segment Documentation
