Dear Experts. My client is export company with the following conditions: Business Case: 1. Delivery Order is a reference to generate Proforma Invoice and Invoice. 2. Proforma Invoice is created for custom duty purposes before posting goods issue. 3. Invoice is created for customer after shipment realization (approx 1-2 weeks after Proforma Invoice created). 4. Both documents have the same data such as material, quantity and pricing, the actual shipment date only stated in Invoice. 5. Receivables and Revenues are recognized upon Invoice release to accounting. Requirement: Proforma Invoice and Invoice should have the same number. SAP Standard Solution: 1. Billing type for both Proforma Invoice and Invoice are specific and only set as internal number. 2. Both documents recorded in table VBRK-VBELN as a key. Question: How can I fulfill the above requirement? Thanks. Zaki | __.____._ Copyright © 2011 Toolbox.com and message author. Toolbox.com 4343 N.
