In SAP Sourcing v9, the ability to integrate with multiple backend system has been introduced. In order to support this integration, the concept of the relationship of the Business System for some Master Data objects has also been introduced.
With this enhancement, there is now the possibility to have Master Data related to different Business Systems. When there is a need to update existing Master Data to a different Business System, it is important to use a properly formatted file to avoid duplicating Master Data.
In order to change objects that are already established within SAP Sourcing and that are identified as local to SAP Sourcing to being correctly marked as replicated from ECC, it is important to to use a properly formatted import file. The key is to use a column with the heading of “CONVERT_TO_REPLICATED” which is set to “TRUE” for each of the business objects to be converted. This must be used in addition to the BUSINESS_SYSTEM External ID.
If the import file is created using the standard “IS_REPLICATED” column heading, the system will create those business objects as if they were new objects instead of updating the Business System on the existing objects.
