Smart Impact app

The Smart Impact app may be used to assess the impact of support packs or custom development changes. It identifies an optimal or most-at-risk set of executables, which when tested will execute each of the changing objects. The Smart Impact returns most-at-risk objects that are in the same application area as the impacting changing object.

The Smart Impact app writes an entry to the Data > Impact Analyses folder, so that its results are available to other analyses.

The depth used by the app to search for referenced objects may be set by an Administrator in the Configuration - Impact Analysis screen’s ImpactAnalysisDepth field. If you don't set this field, the app uses 10 as the default value.

The Smart Impact app may be integrated with a Test Repository to identify hits, gaps and known gaps.

  • Hits are most-at-risk object names for which test assets have been found.

  • Gaps are most-at-risk object names for which there are no available test assets.

  • Known gaps are most-at-risk objects that are not expected to have tests in the specified Test Repository. These are set in the Pipeline’s Known Test Gaps External Data Source.

If required, the gap objects may be used to create test requirements and test execution lists in the specified Test Repository.

If a Comparison system is specified, the app may be configured to compare impactful changing objects and table data on the Analysis and Comparison systems.

The app is provided with one or more of the following on the SAP system to be analyzed.

  • A set of transports
  • A set of objects
  • A set of ChaRM change requests

These provide the Smart Impact app with a set of changing objects. The app identifies an optimal or most-at-risk set of used executables which when tested will exercise each of the changing objects. It also identifies the screens, users and roles impacted by the changing objects. The analysis is driven by the changing objects and by a set of used objects obtained from a Performance History system. Typically, this will be your production system. Note that table content changes are not processed when identifying the most-at-risk objects.

  • Only changing Function (FUNC) objects that are remote-enabled are considered used.

  • Only changing Class (CLAS) objects that call Web Services are considered used.

By default, the Smart Impact app reports the following object types as used, impacted and most-at-risk.

Object type Description
WAPA BSP Application
IWSV Gateway Service
PROG Program
FUNC Function
TCOD Transaction

However, a user with Administrator permissions may customize these defaults as follows:

  1. Select the Administration > Configuration > Impact Analysis folder in the LiveCompare hierarchy.
  2. In the TypesToFind section, deselect the object types to be excluded from the used, impacted and most-at-risk results. Note that if no items are selected, all the above object types will be used as the default value.
  3. Click Save to save your changes.

These changes affect all subsequent runs of the Smart Impact app and Smart Impact Analysis workflow, but they don't affect any existing app or workflow results.

The app produces a Dashboard report and an associated Excel report.

Testing

Parallel impact analysis

You can run the Smart Impact app in parallel with other impact analysis apps and workflows.

Prerequisites

We recommend that you configure the Daily FOL workflow to run each night. This workflow maintains a database of SAP object dependencies for your Analysis system.

The Smart Impact app uses a Pipeline to identify:

  • The Analysis, Comparison, Usage and SAP Solution Manager systems.

  • An External Data Source with TYPE and NAME columns containing a list of business critical objects. This will be identified as most-at-risk if they are impacted by one or more changing objects. If the Business Critical Objects field in the Pipeline is not set, the Smart Impact app uses the Business Critical Objects External Data Source.

  • One or more Most-at-risk Search Test Repositories that will be searched to find test assets that match the most-at-risk executables.

  • A Most-at-Risk Gaps Test Repository, in which test requirements are to be created for most-at-risk objects that don't have matching test assets in the specified search Test Repositories.

  • One or more Most-at-risk Hits Execution Test Repositories, in which tests that match most-at-risk objects are to be created and executed.

Tester Business Critical

If the Pipeline’s Tester Business Critical checkbox is checked, the Pipeline’s Search Test Repositories are searched to find used objects that have associated tests. These objects are treated as business critical, so that impacted objects that have associated tests will be identified as most-at-risk.

Disable Table Content Analysis

If the Pipeline’s Disable Table Content Analysis checkbox is checked, table content changes will be excluded from the changing objects used in this app. If it is unchecked, table content changes will be included.

Before the Smart Impact app is run, you must create a Pipeline that includes the RFC Destinations and Test Repositories to be used in the analysis.

If a support pack or transport has not been applied to the Analysis system, it must be disassembled before the Smart Impact app can analyze it. This can be done in SAP by running the SAINT transaction and selecting Disassemble OCS Package from the Utilities menu. Alternatively, the support pack or transport may be disassembled in LiveCompare using the Package Disassembler app.

The app requires that SAP’s Where Used indexes be up to date on the Analysis system.

A LiveCompare Editor will need to run the Create Object Links Cache workflow from the Prerequisites templates folder to create an object links cache database for the Analysis System in the Pipeline. A system’s object links cache database should be no older than 7 days; its run date may be checked in the RFC Destination’s OLC tab. The Create Object Links Cache workflow may be run incrementally to update the object links cache database with any recent object dependency changes, and to refresh its run date.

A LiveCompare Editor will need to make sure that performance history data is available on the Usage System specified in the Pipeline. Select the RFC Destination in the LiveCompare hierarchy and click the PHD tab. Select the source for performance history data, set a collection schedule, click Save, and then click Update Cache. See the Retrieve performance history data help topic for details.

If you plan to use the app to identify test hits and gaps in a Test Repository, a LiveCompare Editor must run the Create Test Repository Cache workflow from the Prerequisites template folder must be run first in order to populate the Test Repository’s cache.

If you plan to use the app to identify impacted IDocs, a LiveCompare Editor must run the Cache IDoc Impact Data workflow from the Prerequisites templates folder in order to populate the IDoc Impact Cache External Data Source.

If required, the Business Critical Objects External Data Source should be populated with a set of business critical objects that are included in the set of most-at-risk executables if they are impacted by one or more changing objects. The External Data Source is populated from a .CSV file with TYPE and NAME columns. Use the External Data Source’s ‘Replace Data File’ option in the LiveCompare studio to upload your own .CSV file. Note that the Business Critical Objects External Data Source is not used if a different External Data Source is specified in the Pipeline’s Business Critical Objects field.

  • The ChangingObjectsToIgnore External Data Source removes tables whose names begin with ENH or AGR from the set of changing objects.

  • The TransportsToIgnore External Data Source contains regular expressions which are used to filter out transports containing custom objects.

  • The External Data Source contains used objects that are to be ignored during the analysis.

If required, these External Data Sources may be edited in the LiveCompare studio using the ‘Replace Data File’ option.

Express and Standard modes

The Smart Impact app runs in either Express or Standard mode, depending on whether its changing objects all exist in the database of SAP object dependencies you created here.

  • If the Smart Impact app’s changing objects are all in the dependencies database, it runs in Express mode. The app’s Find Object Links (Read Only) action reads the dependencies database directly and doesn’t need to connect to SAP to find any object dependencies.

  • If the Smart Impact app’s changing objects aren’t all in the dependencies database, it runs in Standard mode. The app’s Find Object Links (Read Only) action connects to SAP to find the missing dependencies.

The Smart Impact app typically runs much faster in Express mode.

Run the app

To run the Smart Impact app, select the app from the Apps screen and create an app variant. Complete the Variant screen as follows:

  • Set the Pipeline field to the Pipeline that contains the RFC Destinations, Test Repositories and Business Critical Objects External Data Source to be used by the app.

  • If required, edit the Transports table to provide a list of transports to be analyzed.

  • If required, edit the ChaRM Change Requests string list to provide a list of ChaRM change requests to be analyzed.

  • If required, edit the Objects table to provide a list of objects to be analyzed.

  • Set the Compare ABAP? switch to specify whether the most-at-risk objects will be compared on the Analysis and Comparison systems.

  • Set the Compare Data? switch to specify whether the table keys for changing tables will be compared on the Analysis and Comparison systems. If this switch is set, up to 20 table keys will be compared for each changing table.

  • If required, edit the Execution List Configuration table to provide one or more configuration entries to be associated with the test execution in Tosca Test Repositories, for example /Configurations/Environment1/TDS.

  • Turn on the Cross Reference switch to generate a Cross Reference spreadsheet in the app’s Function Details and Testing Details reports. The Cross Reference spreadsheet lists all the impacted or most-at-risk executables for each impactful changing object. If you switch this on, the app will take a long time to run if there are many objects to analyze.

Click Run. When the variant has completed, its results may be accessed from the App Cockpit screen.
