In the course of introducing SAP R/3, an upgrade from Siebel 99.5 to Siebel 2000 is carried out. The SAP introduction replaces the interfaces between Siebel and the old systems with the SAP R/3 connector.
The Siebel 99.5 system is supplied with customer data, order data and product data from the old systems. The introduction of SAP R/3 makes it necessary to manipulate the legacy data in Siebel 2000 so that the legacy data matches the data in the R/3 system. After migration, data from the SAP system is received and updated (as necessary) using ALE/IDoc technology.
