Process of SAP Controls and checks
1. Master Data Management (Core Setup)
First Step: Data Integrity and Setup
In any enterprise software system, the foundation for smooth operations begins with the accurate and consistent setup of master data. In SAP, this involves creating and maintaining data for materials, vendors, and customers.
Material Master Data Creation and Changes (MM):
The first step in material management is to ensure that the materials the company deals with are properly entered into the system. Materials could be raw materials, finished goods, or consumables, and they need correct data to ensure accurate inventory management and procurement.
T-Codes:
MM01: Create material master data for new materials.
MM03: Display material data for auditing or review.
Audit: Verify that the material data is accurate, complete, and up-to-date. This includes checking for missing or incorrect data in material master records, such as material type, unit of measure, and price control.
Checks:
Ensure material types and procurement types are correctly assigned.
Validate material group codes and vendor-master linkages.
Use MM04 (Material Change Documents) to track changes to material data.
Material Valuation Audit: Ensure that the valuation class, price control (standard or moving average), and valuation area are configured properly.
Vendor Master Data Management (AP):
Vendors are integral to procurement, and accurate vendor data ensures that the organization can process purchase orders, track deliveries, and make payments efficiently.
T-Codes:
XK01: Create a new vendor master record when a new supplier is onboarded.
FK03: Display existing vendor master data to verify details before transactions like payments or orders.
Audit: Confirm that vendor information is up-to-date and consistent. This includes validation of vendor banking details, payment terms, tax information, and contact details.
Checks:
Validate tax codes and payment terms against the vendor’s country-specific setup.
Use MKVZ (Vendor List) to verify the list of active vendors.
Audit changes to vendor master data using XK05 for blocking and MK01/MK02/MK03 for creating and changing vendor data.
Master Data Change Logs: Review changes to vendor details using SCU3 for transaction logs.
Customer Master Data Management (AR):
Customer information must be maintained meticulously to ensure smooth billing, credit management, and timely collection of receivables.
T-Codes:
XD03: Display customer master records to review or audit details.
FD32: Display customer credit information to manage credit limits and payment terms.
Audit: Ensure that customer information is accurate for billing, credit management, and invoicing. This includes verifying customer credit limits, payment terms, and billing addresses.
Checks:
Review credit limit settings in FD32 (Customer Credit Management).
Use VCUSTHIS to view the history of customer master data changes.
Perform periodic audits using XD03 to review customer data for completeness.
Example: A company, "ABC Electronics," creates a new vendor (e.g., "XYZ Supplies") to purchase raw materials for production. The vendor details (tax codes, payment terms, etc.) are input using XK01, ensuring that all purchase orders and payments to the vendor are processed smoothly.
2. Procurement and Payment Flow
Second Step: Procurement and Payment Verification
Once master data is set up, procurement processes begin. This step ensures that the purchase of goods or services is tracked, validated, and payments are made correctly.
Purchase Requisition and Order Controls (MM):
To initiate procurement, employees or departments create a purchase requisition when goods or services are needed. Once the requisition is approved, a purchase order is generated.
T-Codes:
ME51N: Create a purchase requisition for materials needed in production or for resale.
ME21N: Create a purchase order to send to vendors after the requisition is approved.
Audit: Ensure that purchase requisitions and orders are created and approved according to organizational policies. This includes verifying the authorization of requisition creation and changes.
Checks:
Use ME23N to review purchase orders and ensure proper approval and compliance.
Track changes using ME22N to ensure all updates to purchase orders are authorized and legitimate.
Audit requisition creation using ME51N and verify appropriate approvals.
Invoice Verification (AP):
When goods are received, the finance team verifies the invoice received from the vendor against the purchase order (PO) and goods receipt (GR). This is a critical step in the "three-way match" process.
T-Codes:
MIRO: Used to verify the vendor invoice against the PO and GR before payment is made.
ME23N: Display the purchase order to ensure the details match the invoice before processing payment.
Audit: Ensure that invoices are validated correctly against the purchase order (PO) and goods receipt (GR). Verify that invoices are accurate and there are no discrepancies in the amounts or tax codes.
Checks:
Use MIRO to verify the correctness of the invoice by comparing it against PO and GR.
Track changes to invoice verification with SCU3 for audit logs.
Ensure that the invoice details (tax, price, and quantity) match the purchase order and goods receipt.
3-Way Match Checks (AP):
The three-way match check ensures that only legitimate invoices are paid. If any discrepancies occur (e.g., the PO doesn't match the invoice or the goods receipt), payment is withheld until resolved.
T-Codes:
MIRO: Facilitates the invoice verification process where SAP compares the purchase order and goods receipt with the invoice for consistency.
Audit: Verify that the three-way match between the PO, GR, and invoice has been performed properly before payment.
Checks:
Cross-check MIRO with MIGO (goods receipt) and ME21N (purchase order).
Use ME23N to review purchase order details to verify the consistency of data with the invoice and goods receipt.
Example: A vendor sends an invoice for materials purchased. The accounts payable team uses MIRO to compare the invoice with the purchase order (ME21N) and goods receipt (MIGO). If the amounts align, payment is processed.
3. Financial Transaction Posting and Validation
Third Step: Document and Cost Posting
After procurement is completed, financial transactions need to be posted, costs allocated, and profits segmented according to business requirements.
General Ledger (FI):
The General Ledger (GL) is central to SAP’s financial accounting, and all transactions must be accurately posted to the appropriate accounts.
T-Codes:
FB50: Used for posting GL entries directly into the system.
FBV0: Allows users to park documents temporarily before final posting, ensuring proper review.
Audit: Ensure that all general ledger entries are posted to the correct accounts and in compliance with internal financial policies.
Checks:
Use FB03 to display posted documents and verify the correctness of GL postings.
Review changes to GL entries using SCU3 to track document modifications.
Use F.01 to generate balance sheet and P&L statements to ensure proper account balancing.
Cost Object Posting (CO):
Costs must be tracked against specific cost objects, such as cost centers or internal orders, to ensure that they are appropriately allocated.
T-Codes:
KB11N: Used to post costs directly to cost centers.
KB21N: Manually allocate costs to specific cost objects.
KSB1: Display cost center postings to review allocations.
Audit: Ensure that costs are accurately posted to the correct cost centers or internal orders, and that the posting rules are properly followed.
Checks:
Review cost postings using KSB1 (Cost Center Report) and KB11N (Cost Posting).
Ensure that cost allocations are in line with the approved budget using OKP1 (Cost Element Planning).
Track changes and allocations using SCU3.
Profit Segment Posting (CO):
Profitability analysis is crucial to understanding which segments of the business are performing well, such as product lines or geographic regions.
T-Codes:
KE30: Profitability report to analyze performance across various business segments.
KE24: Display profitability data for deeper analysis.
Audit: Ensure that profitability segments (e.g., by product or region) are accurately captured and reported in line with business requirements.
Checks:
Use KE30 (Profitability Report) to analyze segment performance.
Validate profitability segment postings using KE24.
Review FAGL_SPLIT for document splitting to ensure proper segmentation.
Document Splitting (FI):
Document splitting in SAP automatically divides financial postings into different segments (e.g., profit centers, segments) to support detailed reporting and compliance.
T-Codes:
FAGL_SPLIT: Used to configure and manage document splitting, ensuring compliance with accounting regulations.
Example: A company allocates costs of production (materials, labor) to different cost centers for accurate reporting. The financial team uses KB11N and KB21N to post these costs and uses KE30 to analyze profitability by region.
4. Exchange Rate and Taxation Setup
Fourth Step: Maintain Exchange Rates and Tax Configurations
For global transactions, currency exchange rates and tax calculations must be accurate to prevent financial discrepancies and ensure compliance with tax regulations.
Foreign Exchange Rate Maintenance (FI):
Accurate exchange rates are vital for transactions involving foreign currencies. These rates must be maintained regularly to reflect the current market rates.
T-Codes:
OB08: Configure exchange rates and their validity periods.
