A transition to SAP S/4HANA is on everyone’s agenda. Sooner or later you will start your journey to SAP S/4HANA. In such projects you deal with longer runtimes. As a result there are troubles meeting the requested downtime window by the business unit.
A downtime event is always costly for a company. Often not more than a weekend is allowed to ensure an uninterrupted operation. Hence, the downtime can be a showstopper for any project and needs to be kept under control.

In this blog post I would like to introduce the Technical Downtime Optimization app.
It helps upgrade/conversion project members meet tight downtime requirements by providing easy to consume analytics and tailored downtime minimization advices and simulation from continuously updated knowledge base curated by upgrade/conversion experts.


How does it work?

The Software Update Manager (SUM) collects runtime statistics in the UPGANA.XML file. They can be send to SAP along with the SUM feedback form at the end of your Upgrade or Conversion run.



An automated algorithm in the cloud backend processes the data and presents them after approximately three hours. This step is fully automated and doesn’t require any interaction from your side.
Finally you are ready to analyze your data and identify potential downtime savings. 


How to get this app?

There are two ways entering the app:

  1. Using the SAP ONE Support Launchpad
  2. Using the direct link:


If you would like to go for the SAP ONE Support Launchpad then search for the “Technical Downtime Optimization” app. Afterwards add this tile to a group. Now you can see information about the number of maintenance events in the past 365 days as well as the data of the last available event.

Finally you enter the start page and are good to go.



Forgot to send your data?

No problem! With the new upload functionality you are now able to upload your UPGANA.XML and APPLANA.XML file. The processing time of about three hours applies as well.


How to use the app?

On the start screen, set a filter to reduce the number of displayed events or directly choose a desired maintenance event and check the analysis by clicking the event.

The analysis screen is divided into three parts: the header, the time chart and the recommendation part.


The Header
The header of the app always contains information of the displayed maintenance event. Here you will see (1) the installation number, product, host and type of event, as well as information on source and target system including start and end date.
Additionally to that (2) you are able to open the UPGANA.XML and APPLANA.XML files to get more data of the event . Please note, that the APPLANA.XML file is just available for SAP S/4HANA conversions and if created abd uploaded manually.
(3) Furthermore you have the possibility to switch the timeline between “Complete upgrade without tool waiting time” and “… with tool waiting time”.

The Timeline
The timeline (4) consists of an overall runtime and a detailed analysis.
The overall runtime includes Uptime, Downtime and Postprocessing. The detailed analysis is dependent on one of that parts. As we focus on downtime optimization, we directly switch to the orange part, the “Technical Downtime”.


The detailed analysis will now show SUM phases which run during the downtime. When clicking on a downtime phase you will see analysis and recommendation in the recommendation part (5).

The recommendation part
The last part of the app is also divided into three parts.


At the beginning you will read about the chosen phase, its runtime and how to optimize it. Afterwards you see the processes sorted according their duration and the line chart which shows the parallel processes. The granularity of the charts can be adjusted using either more or less bins.


How to check the Financial Data migration runtime?

In order to evaluate the Financial Data Migration runtime choose “Application analytics document” on the top right side of your start screen.


This will direct you to a structured view of the APPLANA.XML file.


In the next version it is planned to have a more detailed analysis on the Financial Data Migration part included into the app.


How to use the Compare View?

The major deliver of release 1.3 was the compare view. You have now the possibility to compare two runs of a recent project. This can be done as follows:

  1. Select a specific run of a maintenance event
  2. Press the “Compare View” button in order to choose the event you want to compare
  3. Select the second event:
  4. See both events and their runtimes next to each other for better comparison.

Using the compare view you have the chance to check what improvements you achieved. In above example the first run was executed using standard methodology. After implementing downtime decreasing parameter and choosing nZDM method in Software Update Manager the overall SUM downtime has been reduced by 57% with major improvements in Main Import (71%) and Data Conversion (72%).



Using the Technical Downtime Optimization app you get easy to consume analytics and simulation from an up-to-date knowledge base to evaluate your runtime and detect possible downtime drivers. This tailored downtime minimization advice is included in the SAP support offering and comes with no extra costs.

      Hi Andreas!

      Very interesting app with important info for management point of view.

      I checked the version 5, released today (28-Sep) of the note 2881515, it brings information about the data migration phase:

      Features of version 2 (released on 01 October 2020):

      It is possible that you can see a visual analysis and evaluation of a downtime-optimized system maintenance procedure to SAP S/4HANA Finance 1909 or higher. However, the statistics of this procedure are not listed in the file upgana.xml, which is the normal basis of the analysis, but in the file applana.xml. This file must be generated and downloaded manually. To do this, proceed as follows:

      a) SAP S/4HANA 1909

      1. Logon to your SAP system and execute transaction FINS_MIG_SATUS.
      2. Check if the data migration is completed. Only in this case, you can generate the file applana.xml.
      3. Open the ABAP Editor (transaction SE38) and execute the report FINS_MIG_APPLANA_XML.
      4. Save the generated xml-file as applana.xml to your local download folder.


      BUT, there is nowhere to upload this file (at least I didn't find it). As the note mentions 01 October 2020, may we expect an update of the app by then?

      Or is this upload/analysis for the applana.xml still not in this release?


      Thank you and congrats for the tool and blog!


      Kind regards,

      Eduardo Hartmann

      Hi Andreas,

      The button is available to upload the files. I uploaded the APPLANA.XML file but nothing seems to have changed in the results.

      Is there anything else that must be done or some part of the app not released yet to consider these data?

      Thanks and regards,

      Eduardo Hartmann
