Configure Automatic Postings  -  OBYC

     OBYC stands for Configure Automatic Postings. i.e When u enter a transaction for the Inventory Management and Invoice Verification it simultaneously updated in Financial and Controlling documents in respective modules by means of G/L accounts.

    E.g. when u does MIGO Transaction after trans MB03 material doc and accounting doc and u can see the complete flow of accounting and material documents. In brief the Postings are made to G/L accounts automatically in the case of Invoice Verification and Inventory Management where the transactions are relevant to Financial and Cost Accounting.

MM – FI Integration

    MM – FI Integration depends on two things namely Valuation class and Movement types like inventory posting(BSX), gr/ir clearing(WRX) or inventory offsetting(GBB). The 3digit codes mentioned are the standard transaction keys provided by SAP for each possible movement type.     They can be found when we run tcode OBYC in IMG.

     In order to create interface between MM and FI we need to assign a G/L a/c from the chart of accounts being used for the co-code for each movement type(transaction) for a valuation class. If the no.of G/L accounts to be posted are more than one as in case of GBB(issues from different stocks or for different purposes) the parameter General Modifications comes into picture the value of which decides the G/L a/c to be posted under different scenarios.

   

In general the flow would be,

    1.In PO Transaction 

---- No integration

    2.When Goods Receipt/Goods Issue

Inventory Account dr (Transaction Key BSX in OBYC)

To GRIR account (T.Key WRX in T-code OBYC)

    3. When Invoice is posted

GRIR account Dr.

Vendor account Cr.

    4. Payment made to Vendor

Vendor A/c Dr

To Bank Clearing A/c Cr.
