Step 1. Maintain FI document number range. Use transaction OMR4 and go to Number range for document types in FI. Select the company code for which you want to create the new number range interval and click on the change interval button. Insert a new document number range by clicking on the insert interval button on top of the screen.for example, I created number range interval 52 with the document numbers 5200000000 – 5299999999. Don't forget to set the external number range check box (Ext).
Step 2. Assign FI number range to FI document types. The second step is to assign the number range created in step 1 to the FI document type for invoices. Again use transaction OMR4 and go to Document type. Double-click on the document type, which you are using for LIV invoices. In my example, I used the SAP standard document type RE. In the number range field, assign the new number range interval 52
Step 3. Maintain MM document number ranges. Use transaction OMRJ and click on change interval button. Insert a new document number range by clicking on the insert button at the top of the screen. For MM documents, I created number range interval 52 with the document numbers 5200000000 – 5299999999. For the internal number range assignment, do not set the external number range check box (Ext).
Step 4. Update MM number range assignment. The last step is to assign the MM number range to your MM transaction via IMG menu path Materials Management>Logistics Invoice Verification>Incoming Invoice>Number Assignment>Maintain Number Assignments for Logistic Documents>Transaction – Assign Number ranges. Two transactions are available. LIV contains the following two internal transactions that are used for the MM document number determination:
RD: manual invoice entry (MIRO)
RS: cancel, reverse invoice (MR8M), evaluated receipt settlement (MRRL), EDI invoice receipt, invoicing plan (MRIS), and revaluation (MRNB).
You need to update the number range interval for transaction RD.
