Dual-Stack Split Procedure - SAP Basis task

This video gives you an overview of the end-to-end dual-stack split procedure transforming a system with both Application Server ABAP and Java into two separate systems performed on a demo system - including split with the setup of a new Java system and the removal of the Java stack from the former dual-stack system. SAP recommends that you move away from optional dual-stack SAP systems where possible and has communicated with which releases of SAP NetWeaver and SAP Business Suite optional dual-stack systems won't be supported any longer. While existing dual-stack systems remain supported in their current release, you can adapt your system set-ups to the recommendation from SAP and prepare future upgrades with the help of the dual-stack split tool.

SCM vs APO for BASIS Admins

At a high level SAP SCM is a product suite of which SAP APO is a part. APO is a planning specific product within the SAP SCM suite.

SCM = APO + SNC + Event Management + EWM

The suite of SAP SCM solution consists of following solution to fulfill demand on time.
  • Sales, Inventory, and Operations Planning (S&OP)
  • Demand and Supply Planning
  • Collaborative Response Management
  • Warehouse Management
  • Transportation Management
  • Supply Chain Analytics
  • Service Parts Management
  • Track & Trace
  • Manufacturing and Supply Planning


As a Basis Administrator supporting SAP APO [SCM] production landscape one has to acquire the following admin skills to manage the systems.

  • Overview of APO
  • APO Core Interface
  • Core Interface (CIF) monitoring
  • APO optimizer
  • APO and BW
  • APO authorizations
  • APO performance
  • APO disaster recovery strategies
  • New functions in APO 3.1 and liveCache 7.4
  • Troubleshooting
As an APO admin you would be dealing with some of these activities:

Monitoring of CIF and qRFC
Software maintenance
Consistency checks
SAP BW Integration in SAP APO
Livecache administration
Backup and recovery scenarios

tags:adm 355, Monitoring SAP APO systems and troubleshooting,


APO as a application is tightly integrated to execution (OLTP) system like ERP using a standard interface called Core Interface Function (Interfaces - Core Interface (CIF) and BAPIs). It also has full BI (erstwhile BW) component for Data Mart as well as Reporting functionalities.

The Migration Monitor is a tool which helps you to perform and control the unload and load process during the system copy procedure. If you want to use the table splitting feature, both the export and import must be done using the Migration Monitor.

MIGMON is Used for data loads and unloads.

Migration Monitor can be used only for ABAP stack or ABAP part of dual stack, not for Java stack.

SAP KERNEL Version How to check for Java System?

Login to <sidadm>
Type this command : disp+work -v|more

You will see the kernel Patch level

Restriction with stack xml - SAP MOPZ

a.    It’s not possible to create a stack xml file to update just one or two or some specific                components, mopz doesn’t work this way, you need upgrade the complete stack                    together.
b.    It’s not possible to create a mopz just to update patches,we can only just INTEGRATE patches in mopz, but not generate a stack xml file for patches alone. 

For example if customer wants to update the patches of Netweaver    7.30 SP05,he needs upgrade to SP06 or a higher SP level together with the patch levels.


There are three ways to deal with Daylight Saving Time:
A Two hour downtime method: Completely avoid running SAP system during this double hour.
B One hour downtime method: See Note 102088
C Zero downtime method: Use the default “stretched time”.

For customers who choose the way A, a switch is provided to shut off the stretched time. For details please  see Note 102088.

As the "stretched time" is set as the default, all customers should decide for themselves whether they can accept the disadvantages of the "stretched time". If they can, the system can continue to run.

If not, the customer needs to choose way either A or B.

Be aware of that, "stretched time" is first introduced since release 46C. For older releases there is no such a choice.

How to code with “stretched time” by your own, so that it could run during the “double hours”, please see the “Information for the ABAP Developer”.

We know of at least one example of an application which cannot work with the "stretched time":
Component "IS-H," SAP Patient Management (see customer message 0000298268 120 050 410 2005).

"Letting the “double hours” run first, and then dealing with any possible errors" is a rather risky approach.
Type 1) errors are not very likely to occur, but type 2) errors are almost certain to occur. You need to
analyze your situation exactly in order to choose the right method for you.
