It is very easy to understand Fi-MM intergration the below details may help you to understand very easily..

FI-MM: The integration between FI-MM happens in T-code OBYC.

1. When PO is created :


No Entry -

2. When GR is posted

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.

Points to know : Movement Types, Assignment of Movement types to T-keys (T-code OMJJ), Value string (I also need some information on this) , OMWN and OMWB transactions.


There is a close integration b/w FI & MM, actually document flows from MM to FI in the following areas such as,

1. Movement Types:

Used to enable the system to find the predefined posting rules determining how the accounts of financial accounting system are to be posted & to update the stock fields in the matrl master data.(Goods Receipt, Goods Issue, etc)

2. Valuation Class:

Assignment of material to grp of gl account, used to determine the gl accounts that are updated as a result of goods movement.

3. Transaction/Event key:

Used to control the storage or filing of documents & assignment of documents.Used to differeniate b/w various transactions such as goods movement tht occur in inventory.

4. Material Type:

Each material should assign mtrl type in mtrl master record used to update whether changes made in qty are updated in material master record & change in value also updated in stock account.

Hi Vissu,

FI-MM trigger point is T.code OBYC.

I will give you overview. Actually when MM people doing there Purchase cycle. In PR & PO there is no accounting document will generate but at the time of MIGO & MIRO accounting document will generate. For that purpose we have to assign GL a/cs in transaction keys and transaction keys are :

In MIGO A/Cing doc's will be Transaction keys

Raw material/Inventory A/C Dr..........XXX BSX

To GR/IR A/C.......................................XXX WRX

In MIRO A/Cing doc's will be

GR/IR A/C Dr.......................XXX WRX

To Vendor A/C.....................XXX (picks frm Accounts payable n PO)

Apart from OBYC, Concentrate on OMJJ w.r.t Mvt. types, OB52 FI periods which may stop Stock posting.
