GR/IR Account Determination Exit a brief

Write-Up: Enhancement LMR1M002 (MM-IV)

The enhancement LMR1M002 is a customer-specific functionality in SAP Materials Management (MM) that enables the determination of GR/IR clearing accounts based on purchase order data. This feature provides greater flexibility in handling specific account assignment requirements during goods and invoice receipts.

Released with SAP Release 4.6B, LMR1M002 is especially useful for organizations that require custom logic for managing their GR/IR clearing account postings. It utilizes EXIT_SAPLKONT_011, a customer exit function module, to achieve tailored account groupings for the WE/RE (goods receipt/invoice receipt) account determination.

Functionality Overview

Customer Exit:
EXIT_SAPLKONT_011 is the main function module used in the enhancement. It integrates with the MR_ACCOUNT_ASSIGNMENT function module to customize account determination during the following scenarios:

1. Posting a goods receipt for a purchase order.
2. Posting an invoice in conventional invoice verification using Transaction MR01. (Note: This method is no longer maintained as of Release 4.6C.)
3. Posting an invoice in logistics invoice verification using Transactions MR1M or MIRO. (In Release 4.6C, MIRO fully replaces MR1M.)

The function module accepts purchase order data, such as the purchase order number (EXIT_EBELN) and item number (EXIT_EBELP), as import parameters. It returns the appropriate account grouping code, enabling the system to determine the correct GR/IR clearing account for postings.

Key Features and Implementation

Customization Possibilities:

• The enhancement allows for GR/IR account assignment logic based on specific criteria such as vendor, invoicing party, or freight supplier.
• Customers must ensure that postings for goods receipt and invoice receipt are made to the same GR/IR clearing account, as the system does not enforce this check.

Example Logic:

To define GR/IR clearing accounts based on the vendor or invoicing party:

1. Retrieve vendor details from the purchase order:

   ABAP
   SELECT * FROM EKKO INTO CORRESPONDING FIELDS OF EKKO              WHERE EBELN = EXIT_EBELN.  

   • EKKO-LIFNR: Vendor
   • EKKO-LIFRE: Invoicing party

2. Determine the freight supplier:

   ABAP
   SELECT * FROM KONV INTO CORRESPONDING FIELDS OF KONV              WHERE KNUMV = EKKO-KNUMV                AND KDPOS = EXIT_EBELP.  

   • KONV-LIFNR: Freight cost vendor

Prerequisites:

• Activate LMR1M002 in customer enhancements.
• Configure account grouping codes in Customizing for account key WRX under the relevant rules.

   • Vendor information from the EKKO table.
   • Freight suppliers using conditions in the KONV table.

For example, the following ABAP code retrieves vendor details:

ABAP
SELECT * FROM EKKO INTO CORRESPONDING FIELDS OF EKKO              WHERE EBELN = EXIT_EBELN.
