SAP Analytics Cloud – Private Versions Statistics and Analysis

Private Versions Statistics and Analysis will be general available with Wave 2022.21 and 2022.Q4 QRC Release.

How will it be deployed?

It will be deployed automatically into the side navigation under System > Performance.

It will also be deployed automatically into Files > System > Common > SAC Content.

Alongside with the Story you will find the underlying Model VERSION_STATISTICS_BASE.

What is the purpose of the Private Versions Statistics and Analysis?

As part of the ongoing project SAC Content which helps administrators to answer various questions in regards to performance, housekeeping, usage and many more we introduce the new Story Private Versions Statistics and Analysis. It helps administrators and support to get an overview of the private versions that have been created in the SAP Analytics Cloud Tenant.

Please check the existing content for the big picture and learn how you can use the content:

SAP Analytics Cloud Performance Benchmark

SAP Analytics Cloud – Administration Cockpit

SAP Analytics Cloud Performance Analysis Tool

SAP Analytics Cloud Backend Error Messages

SAC Data Management Jobs Statistics and Analysis

The information helps the administrators in both performance and housekeeping.

Performance:

It aims to address potential performance issues caused by users who are currently working with planning models. We want to highlight the biggest models that are currently in use. This information enables you to make version creators aware of their versions size and the potential high memory consumption they might cause.

Example:

If a public version is in edit mode, a private version will also be created that allows you modify the data without interfering with the original version until it has been saved and thus, published. This edit mode suggests you work on the public data directly but you’re working on a copy, a private version of the data container that is only visible for you. It is called “public edit mode”. This kind of private versions created invisible during a public edit mode are known sources for potentially high memory consumption and expensive query processing because of the big amount of data. Whenever a user edits a public version, the whole data in the model is copied into an internal private version since the whole dataset needs to be prepared for potential modification. This is a common root cause for very big private versions.

To avoid this, we introduced the concept of planning areas last year. Please check the following blog post to check if you can apply it in your scenarios:

help.sap.com – Planning on Public Versions

help.sap.com – Optimize Planning Models Using the Planning Area

Blog – Introduction to the planning area optimization for SAP Analytics Cloud/

The new Private Versions Statistics and Analysis help you to identify the scenario above and other large versions.

Housekeeping:

This content will be extended with the next releases. Please stay tuned.

      Hi Thomas Fery

      Very welcome addition that could finally give planning modelers (and users!) more insight in their operations!

      We would like to share & use the content but we've noticed there is no authorization on the VERSIONS_STATISTICS_BASE model if the standard delivered SAC 'Admin' role is not granted...

      This is not the case for the previously delivered statistics/performance models.
      Is there any reason for this change in approach? As it will limit our adoption.

      Hi Jef Baeyens,

      there should not be any difference to any other model deployed in SAC Content folder. The logic is the same..

      If you are facing an issue here please log an SAP Incident.

      Thanks,

      Thomas

      Hi Thomas,

      We found out reading data from the Version statistics model only works when assigning 'Full Data Access' option in SAC role setting, which is not acceptable for us as it poses security risk and should only be assigned to few users, as described in help document https://help.sap.com/doc/00f68c2e08b941f081002fd3691d86a7/2022.22/en-US/184b5d5493bb4919b06e60947868433a.html

      Other models in the 'SAC Content' folder did not require this, so as you suggested we have logged OSS incident (870708/2022).
