SolMan 7.2 is based on NetWeaver 7.4 but no longer uses a double-stack architecture. Instead, the ABAP and Java stacks run independently on separate systems. It also supports SAP HANA as the database. Java hubs like the Enterprise Portal are supported. When splitting a dual-stack system, the Dual Stack Split tool is used. SAP recommends downloading the latest tool support package and patch level from their website when starting a new provisioning project.

1. End of the double stack
SolMan 7.2 is based on NetWeaver 7.4. However, the architecture differs in that the
Solution Manager in the current version no longer runs on double-stack architecture.
Instead, the two stacks (Abap and Java) run on two independent systems. In addition,
the NetWeaver 7.4 platform supports the use of Hana as a database, which makes it
possible to use Solution Manager in conjunction with a Hana DB.
JAVA Hubs:
Java-based hubs such as SAP Enterprise Portal, SAP Process Orchestration, and SAP
Business Process Management is supported.
In order to split system, we need to use Dual Stack Split tool
(SWPM*.SAR)
