The purpose of this document is to provide end user documentation on System Copy GT. This is an accelerated version of the standard SAP transaction BDLS. This is a transaction entitled “Tool: Conversion of Logical System Names” the purpose of which is to update all database tables that contain “logical system” fields. The most common use of this transaction is as a part of the system copy process, performed by the SAP Basis administration team. Once either a database copy or client copy has been performed from the source system (e.g. production) into the target system (e.g. pre-production / test) then this transaction must be run to adapt the runtime environment to the current state of the data. The type of ABAP stack system (e.g. ECC, BW) will determine how many and which tables must be updated. Typically, for an ECC/ERP system there are in excess of 1500 tables that must be updated. With the standard SAP BDLS transaction, this process can take anywhere from 1 hour to 5 days dependent upon the amount of data within that system. System Copy GT enables a significantly accelerated version to execute this process much faster. Powered by Diffuser, it uses multiple processors to achieve this acceleration. Furthermore, it allows to execute multiple system name conversions in a single run.
This document describes pre-requisites and additional parameters required to execute System Copy GT.
