mm/fi integration

as a sap mm functional consultant what are the configurations in mm side about the mm fi integration

[Jeremy_Deo]

Hello dear user,

And thank you for asking your question in the SAP Community blog.

If you're working as an SAP MM consultant, and you're looking at the MM-FI integration, your main job is to make sure inventory movements and invoice processing in MM trigger the right FI postings that’s where config on the MM side comes in.

Here’s what you actually need to look at:

1. Valuation Area

• Set whether the system does valuation at plant or company code level.
• Usually done in config early on.
• Important because it impacts how accounts are picked.

2. OBYC - Account Determination

• This is the big one.
• You tell SAP which GL accounts to hit when certain things happen — like goods receipt, invoice receipt, or a goods issue.
• You map transaction keys (like BSX, WRX, GBB) to GL accounts based on:
• Valuation class of the material
• Valuation grouping code (tied to the plant/company code)

3. Valuation Class / Material Types

• Material types (e.g., ROH, HALB) control which valuation classes you can use.
• Valuation class is a driver for account determination — e.g., raw materials hit one account, finished goods another.

4. GR/IR Account

• This is the temporary clearing account used between goods receipt and invoice receipt.
• Set up under WRX in OBYC.
• You have to make sure this is maintained for each valuation class.

5. Price Control (S or V)

• Set in the material master (Accounting 1 view).
• S (Standard price) means any difference goes to a price difference account.
• V (Moving average) means the system adjusts inventory value with each receipt.

6. Tax Codes

• You configure tax codes in FTXP.
• They come into play during PO and invoice posting, and they trigger tax-related entries in FI.

7. Movement Types

• These control how the system behaves during goods movements.
• You can control if they trigger FI postings, which account modifier they use (that affects OBYC), etc.
• Config is done in OMJJ.

8. Vendors (FI Link)

• Vendors are created in BP with the FI role.
• You have to assign the correct reconciliation account so when you post invoices, they hit the right line in FI.

9. Material Ledger (If Used)

• If material ledger is active (e.g., for actual costing), it changes how postings work.
• Not always active, but if it is, it affects price variances and inventory valuation.

I hope this will help answer your question.

Best regards,

Jeremy
