[Problems and Needs]

In the SAP system, how to set the debit and credit of integrated documents according to traditional accounting practices? It is customary for traditional financial accounting to understand the balances of borrowers and lenders in the following ways. However, when the SAP system processes business, it does not properly handle red letter accounting (reverse accounting), resulting in the main business cost accounts and borrowers having balances:
 

[Approach]

① Create a custom data table to store the debit and credit balance directions of defined accounts.
 

The FI voucher header field BKPF-AWTYP (reference transaction) is used to indicate the source of the voucher.
 

Note: When manually entering the voucher, the BKPF-AWTYP field is empty during header verification and line item verification. The BKPF-AWTYP field will only have a value when the voucher verification is completed.
The accounting voucher header field BKPF-GLVOR is used to record "Business Transaction" and can be used to distinguish the sources of various vouchers.
In other words, documents posted to SAP-FI through different modules or channels are distinguished by this field. For example, through billing of the SD module, this field is SD00.
So how do we know what various business transactions mean? The explanations in different languages can be queried through the T022T table.
 

② To facilitate maintenance, define a data maintenance view.
 

③ SM30 transaction code maintenance.
According to financial business needs, set debit and credit balances for various types of integrated vouchers (WE purchase warehousing, RE purchase settlement, WL sales issue, RV sales invoicing, WF production warehousing, WA material picking out, etc.) according to accounts.
 

④ Open the field that allows substitution, transaction code SM30, view VWTYGB01.
 

⑤ Activate fields that allow substitution, transaction code SE38, execution program: RGUGBR00.
 

⑥Set alternative GGB1.
 

In the alternative outlet, set the U203 outlet.
 

​​​​​​[Test Verification]

After setting up as above, next in the test system, test various integrated vouchers: WE purchase warehousing, RE purchase settlement, WL sales outbound, RV sales invoicing, WF production warehousing, WA material picking out, etc.
