General Information About SD-FI Interface

The following post is focusing on the generation of the accounting document.

The main purpose is to presentate the most important programs and tables involved during the process.

General information

During release of a billing document to accounting, the relevant fields of the SD invoice (fields of VBRK, VBRP, VBPA, KONV tables)  are transfered to the interface tables XACCHD, XACCIT, XACCCR.

On FI side these interface tables are used to transfer the data to the necessary modules in FI/CO.

On accounting side the most important tables being filled are BKPF, BSEG and BSET.

As a result the customer line item on FI side is created, that equals to the value that has to be payed by the customer. Furthermore revenue and tax lines are created. A summarization takes place if possible or if there is a special customizing setting for it (see SAP Note 36353).

Function module that starts the SD-FI Interface

The most important modules are the function module RV_ACCOUNTING_DOCUMENT_CREATE for creating accounting documents for individual documents, the function moduleRV_ACCOUNTING_DOCULIST_CREATE for creating accounting documents for invoice lists and the Include LV60BF00 that contains the most important subprograms.

RV_ACCOUNTING_DOCUMENT_CREATE (LV60BU01)

triggered by:

RV_ACCOUNTING_DOCUMENT_CREATE converts the billing document into the interface structures ACCIT, ACCCR and ACCHD and the internalinterface tables XACCIT, XACCCR, XACCHD are filled. These are then converted in Function AC_DOCUMENT_CREATE into the accounting document tables BSEG (accounting segment), BSET (taxes) and BKPF (document header). An ACCHD line is created for each and every billing document.

ACCHD:

The structure ACCHD contains the header information for the accounting document. It includes, for example, the time of entry, the name of the person entering the data and the transaction which was used to create the document.

ACCIT:

The structure ACCIT contains basic posting information including the currency information. You can see the billing item to which an ACCIT line belongs in the field ACCIT-POSNR_SD.

ACCCR:

The sturcture ACCCR contains the rate and currency information for customer, tax and G/L account lines. At least one ACCCR is created for each condition, customer or tax line. The ACCIT line belonging to an ACCR line can be identified using the field POSNR (ACCIT-POSNR) .
