INTEGRATION OF SAP MODULES

SAP MM and FI INTEGRATION
Process Flow in MM
Step 1 Generating purchase requisition( PP-MM involved)
Step 2 Making inquiries (MM)
Step 3 Raising purchase order (MM)
Step 4 Release of purchase order ( MM)
Step 5 Goods received from vendor ( MM and FI )
Entry will be Raw Material Inventory a/c Dr.
GR/IR clearing a/c Cr.
Step 6 Invoice verification and quality assurance (FI and MM)
Entry will be GR/IR clearing a/c Dr
Vendor a/c Cr
Step 7 Goods issued for consumption(MM, FI and PP)
Entry will be Raw material consumption a/c Dr
Raw material inventory account Cr
Step 8 Production receipt( FI, MM & PP)
Entry will be Finished
goods inventory a/c Dr
Change in stock Cr
Step 9 Finished goods delivered to customer(MM, SD & FI)
Entry will be Change in stock Dr
Finished goods inventory a/c Cr
Step 10 Raising invoice on customers( SD & FI)
Customers a/c Dr
Sales a/c Cr
Step 11 Receipt of payment from customers( Same as SD-FI integration)
CUSTOMIZATION STEPS
Main screen of FI-MM integration is OBYC Here we have to link the MM movement types to FI G/L accounts.
Assign Following G/L accounts to movement type according to valuation class. BSX- Raw material Inventory account GBB- Raw material consumption account WRX- GR/IR clearing account

1. In SAP you will always get integration with other modules. SD will interact with FI, MM will interact with SD :-
1a. Looking at MM and SD interaction first, take the scenario of a third party order process. This process uses a purchase order (which is sent to your vendor). Also invoice verification is used further along the process to check that the invoice you send to your customer is the same material and quantity as that which the vendor sends to you (but obviously shipped directly to your customer).
1b. Billing is an SD function. But SAP needs to know, when processing a customer's payment, to which GL account the payment has to be processed. For instance payment of a UK based material would be placed in a different GL account to that of a non-UK based material. Furthermore, a UK based customer may have a different GL account to that of an Export customer. This is configured in Account Determination.
2. ABAPers are there to essential do some bespoke development. Your integration, or interaction, with them would be when specifying the tables, fields, input fields, a simple process explanation, data mapping (if doing an interface from one system to another) etc. *-- Shahee
The link between SD and MM :-
1. When you create sales order in SD, all the details of the items are copied from Material master of MM.
2. MRP and availibility check related data is also taken from MM although you control this data in SD also.
3. While you create inbound/outbound delivery with reference to a sales order,the shipping point determination takes place with the help of the loading group, plant data, shipping conditions etc. This also refers to Material Master.
4. The material which you are entering in a sales order must be extended to the sales area of your sales order/customer otherwise you cannot transact with this material.
There are many such links between SD and MM.
Now the link between SD and FI :-
1. Whenever you create a delivery with reference to a sales order, goods movement takes place in the bacgground. eg. In case of standard sales order, you create an outbound goods delivery to the customer. Here movement 601 takes place. This movement is configured in MM. Also, this movement hits some G/L account in FI. Every such movement of good s hits some G/L account.
2. The accounts posting in FI is done with reference to the billing documents (invoice, debit note, credit note etc) created in SD. Thus this is a link between SD and FI
3. Tax determination: In case of a tax determination also, there is a direct link between SD and MM

SD Transaction Code Flow:
Inquiry / Document type IN Tcode for creation VA11,VA12,VA13. tables VBAK,VBAP
Quotation / QT Tcode for creation VA21,VA22,VA23. tables VBAK,VBAP
Purchase Order PO Tcode for creation ME21,ME22,ME23. tables EKKO,EKPO.
Sales Order OR Tcode for creation VA01,VA02,VA03. tables VBAK,VBAP
Delivery LF Tcode for creation VL01,VL02,VL03. tables LIKP,LIPS
Billing MN Tcode for creation VF01,VF02,VF03. tables VBRK,VBRP
To create a sales order we need purchase order number and custmer number. Before that, to create a purchase order we need to have material no, vendor no.
To create vendor tcode is xk01(create), xk02(change) , xk03(display) Tables are lfa1.
To create custmer tcode is xd01, xd02, xd03. Table is kna1.
After creating sales order using this no we can create delivery note tcode is vl01.
