Integration of FICO with Other Modules

What are the steps for integration of FICO with other modules SD, MM etc. ?

Some basic information :

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.
   
 FI-SD Integration: The integration is done in T-code VKOA

  1. Sales Order Created 

        ---No Entry---

  2. PGI done (Goods issue)

      Cost of Goods Sold     Dr (Configured in OBYC GBB T-Key)
           To Inventory Account

  3. Billing document released to Accounting

        Customer Account Dr.
              To Sales Revenue Account (ERL T-key in Pricing procedure)

  Note : The GL account is assigned to this ERL in VKOA

  4. Payment Received

        Bank Clearing A/c Dr
                       Customer A/c Cr. 

Points to Know : Good to understand the pricing procedure and how the different transaction keys are used like ERL, ERS etc.
