Strategies for Loading Data in SAP Commerce Cloud

In almost all SAP Commerce Cloud projects you have different teams working together across different environments. Having the right data in the right environment is critical to ensuring your solution is working correctly. In this article we outline ways for you to configure and to manage loading data, to ensure your data is properly separated and you don't end up with conflicts. You will also learn practices around anonymizing data and the various options for importing data from legacy systems as part of a migration.

Data Separation

By default, in SAP Commerce Cloud when you run ant initialize or ant updatesystem, it will import coredata and sampledata via ImpEx. With this setup there is no clear notion of production data. In the context of a project you will often need to manage three different types of data:

  • core / common / essential data: currency, catalog, languages, etc.
  • testing / sample data: sample category, sample product, sample store, testing users, representative content, etc.
  • initial / update / production data: full product catalog, initial website content, etc.

For loading this data you can use the convention over configuration approach.

Consider the core / common / essential data will be imported whatever the use case: init / update and dev / prod

Recommended Practices for Loading Data

It is a recommended practice to deploy sample data in you Local and DEV environment, in order to have a quickly working SAP Commerce Cloud solution. The data being loaded should account for the possibility to perform automatic smoke/non-regression tests faster. 

Production data should be deployed in your STAGE and PROD environments for:

  • initial load
  • deployment testing
  • performance testing
  • for updating data

Sample Data

Sample data should not depend on Product data. This data has to be as "light" as possible. The purpose is to capture essential web-store content in order to test key features present into the solution. For example, Website/CMS content does not have to be exactly the same–often  editorial content is not relevant for developer/tester teams.

User Acceptance Test (UAT) Data

By definition, UAT data is similar as sample data. Acceptance tests will be based on sample data provided by developer team. 

In the case where your business team wants to contribute to the solution before the go-live, the development team should be involved. Indeed, during your project, contributions by the business team must be considered as development task, because the solution has not been stabilized and one or more deep changes could be introduced.

After the go-live, the business team will contribute on the solution directly in PROD. So they should not interfere with UAT data.

No direct business team contribution should be allowed before go-live

Production Data

By definition, production data is volatile and updated by multiple sources. It cannot be used as a base for testing a new release.

Moreover, when you deploy a new release which embeds data, you should pay attention that it can be applicable just for specific time. Indeed, production data has to be aligned with data change introduced by the release itself. Best way to ensure that release data change is compatible with current production data is to test it in STAGE. For that, you can use Snapshot/Restore Cloud Portal capability.

How to Separate Data


When you start your project you should include time to refactor the  *SystemSetup  java code that is called out of the box as well as generated during  modulegenYou have to remove explicit sample data import. Later, sample data will be imported by  and the "AutoImpEx" feature.

If project time constraint doesn't allow you to refactor data loading strategy, CCv2 is still supporting legacy JSON approach (configuration over convention) which is described in help documentation : Configuring Commerce Update Parameters. This approach is not recommended for medium/long term. It complicates your solution.

Review existing Folders and Files Organization

By default, in each extension you could have resources/ext/import/coredata and resources/ext/import/sampledata folders.

You need to add two more folders to manage all the use cases:

  • resources/ext/import/initdata
  • resources/ext/import/updatedata

Then, you need to review subfolders and files naming in order to be sure they will be imported in right order. Indeed, ImpExSystemSetup is using alphanumeric sorting.
private List<String> scanDir(final ExtensionInfo extension, final String path, final String regex)

Extensions ImpEx Loading Order

Between the extensions, you need to ensure they're loading the ImpEx files in the right order. For that, you just have to declare the dependency in extensioninfo.xml.  When ImpEx of a specific extension (A) should be loaded before another one (B), you just have to set in extension (B) the dependency of extension (A).

<extension ... name="extensionA">
       <!-- use to force impex loading order across the extensions. Impex extensionB will be loaded before extensionA -->     
		<requires-extension name="extensionB"/>


Local and DEV

In this environment, you should import only sample data. For that, you just have to point on the right folder by setting the following properties.
#NOTE: replace ext by your custom extension name

Locally, you can run ant initialize/updatesystem  to import this data set.

When configuring your deployment to DEV , you can use either Initialize database or Migrate data data migration modes to import this data set.


In your STAGE or PROD environments you should import only production data. For that, you just have to point on the right folder.

#NOTE: replace ext by your custom extension name

In STAGE/PROD, you should use migration mode Initialize database for your initial deployment. Once you have loaded your data and have gone live, you should not initialize the database.


Note : 01 represents the release number. Each release could have different data set for updating procedure.

In STAGE/PROD, you should use migration mode: Migrate data

In more complex development/release organization, Patches approach could be more suitable


  • create a new extension (ant extgen / training)
  • create new folder in extension training resources/training/import/sampledata
  • set in 
    • update.executeProjectData.extensionName.list=training
    • training.projectdata-impex-pattern=training/import/sampledata/**/*.impex
  • create two ImpEx for adding products in electronics catalog : 001-products.impex and 002-products.impex
  • add in extensioninfo.xml  <requires-extension name="electronicsstore"/>
  • run a new init (ant initialize -Dtenant=master)

Then you should see this kind of trace in console.log

java] INFO  [main] [ImpExSystemSetup] AutoImpEx for extension 'training' will use userdefined filepattern 'resources/training/import/sampledata/**/*.impex' for creating the project data...
[java] INFO  [main] [ImpExSystemSetup] importing resource : /training/import/sampledata/001-products.impex
[java] INFO  [main] [ImpExSystemSetup] importing resource : /training/import/sampledata/002-products.impex

Procedure for Deploying Data in Production

First Load (Initial Go-live)

Ensure that data folder resources/ext/import/initdata/ contains all the data required for go-live.

Update STAGE/PROD to point to the right ImpEx folder

Check migration mode: Initialize database

Next Load

Each new release deployment will demand to

  • create a new data folder resources/ext/import/updatedata/RXX/
  • update STAGE/PROD to point on the right ImpEx folder
  • check migration mode: Migrate data

updatedata must be tested on STAGE within latest production data

After Load

When updatedata has been pushed correctly in PROD, it could be suitable to update sampledata in order to include essential content (CMS, Product, Customer). That's required for testing critical features.

Please remember, sampledata is not (won't never be) the exact copy of production data

Then, resources/ext/import/updatedata/RXX/  of previous release should be removed. Indeed, this group of ImpExes should not be used anymore.

Keeping STAGE Data Aligned with PRODUCTION

Once your project is live, your STAGE environment should be used for acceptance and regression testing. Having prod-like data in your STAGE environment will ensure you can identify bugs that may come from data issues before you deploy your build to production. It is recommended that you should periodically sync your STAGE environment with latest data from PROD. To accomplish this you can use the  Snapshot/Restore Cloud Portal capability:

  • Take a snapshot of your PROD environment
  • Follow the steps in Restore with Anonymized Production data to restore the snapshot to your STAGE environment.  You should create your own job to anonymize data that meets your requirements for data privacy, but you can use the code below as an example of anonymizer job
public class AnonymizerJob extends AbstractJobPerformable<CronJobModel> {

    private CustomCustomerService customerSerivce;
    private ModelService modelService;

    public PerformResult perform(CronJobModel cronJobModel) {

        // All users attached to UserGroup="customergroup";
        Set<CustomerModel> customers = customerSerivce.getAllCustomers();
        for (CustomerModel customer : customers) {
            // we cannot be used customer.code which contains email address sometime.
            String anonymizedUser = "REPLACED_" + customer.getPk();

            for (OrderModel order: customer.getOrders()) {

            for (AddressModel address: customer.getAddresses()) {
        return new PerformResult(CronJobResult.SUCCESS, CronJobStatus.FINISHED);

    private void anonymisedPaymentInfo(PaymentInfoModel paymentInfo) {

    private void anonymisedComments(List<CommentModel> comments) {
        for (CommentModel comment: comments) {
            String anonymizedComment = "REPLACED_" + comment.getCode();

    private void anonymisedFrauds(Set<FraudReportModel> fraudReports) {

        for (FraudReportModel fraud: fraudReports) {
            String anonymizedFraud = "REPLACED_" + fraud.getCode();

    private void anonymisedAddress(AddressModel address) {
        // address.code doesn't exist. we have to use pk instead of.
        String anonymizedAddr = "REPLACED_" + address.getPk();

 Options for Migrating Data from Existing/Legacy Systems

In the previous sections we discussed loading data into SAP Commerce Cloud environments. Often you may find initial data is taking from other existing/legacy systems (i.e. not SAP Commerce Cloud). In this section, you will see how to get your data into SAP Commerce Cloud.

For SAP Commerce OnPrem to SAP Commerce Cloud data migration, you should follow the standard procedure.

Data Considerations

The old saying "garbage in, garbage out" is extremely important to recognize when migrating data into SAP Commerce Cloud. If you are bringing over data that is:

  • incorrect
  • poorly formatted
  • no longer relevant

then you're just wasting your time and resources. As part of your business requirements you should have already outlined which data needs to be migrated, so ensure you're only focused on that data, and you're accounting for any reformatting that needs to be done. Consider using some sort of middleware to help with this process.

It is recommended to not try to migrate content management system (CMS) data. This data is probably much too specific to your existing system and it cannot be mapped easily to SAP Commerce Cloud. It is recommended to start from scratch and leverage the capabilities within SAP Commerce Cloud, but if this is not possible then you should port this content manually page by page.

Data Migration Strategies

If you do require the migration of data there are typically three options for getting it into SAP Commerce Cloud:

Whenever possible, try Git / ImpEx-based migration covered in the beginning sections of this article. The main advantage of ImpEx over other options is that simplicity and ability to start fresh with a new datamodel, getting rid of some design decisions from the past. Always keep the need and cost to migrate the old data in mind.

In the table below we outline the three options along with the criteria, you may require for data migration.
Criteria \ Type of data migration Git / ImpEx-based initialized and delta migrations Cloud Hotfolder / CSV File  Inbound OData / HTTPS

No downtime (multiple delta migrations until migration complete)

No downtime (multiple delta migrations until migration complete) No downtime (multiple delta migrations until migration complete)
Reusability Custom initial and delta migration scripts required Custom initial and delta migration scripts required Generic import procedure for existing data model. But calling system must be adapted (e.g. the middleware SAP Integration Suite)
Project data migration effort




Prerequisites Data model mapping from source to target

Data model mapping from source to target

Azure Blob Connector for legacy system or Middleware

Data model mapping from source to target

OData integration for legacy system or Middleware

Advantages Simpler and shorter migration It can be used after migration for synchronizing more data It can be used after migration for synchronizing more data
Drawbacks It is one shot data loading. It cannot be used as integration point It will create integration point when it could not be necessary  It will create integration point when it could not be necessary

How to Export/Import CMS Data

One of big challenge for developer team is to maintain sampledata according what the webmasters are updated directly in PROD for the Content Catalog (CMS data).

A good idea is to export specific website content page though HAC by using export ImpEx script. Then, this content should be reviewed manually in order to fit with existing sampledata

INSERT_UPDATE ContentPage;catalogVersion(version, catalog(id))[unique=true];uid[unique=true];name;masterTemplate(uid);label;defaultPage;approvalStatus(code);homepage
"#% impex.exportItems( ""ContentPage"" , false );"


Data loading strategy is one of the often overlooked elements to delivering a successful project. Having the right data loaded in the right environment can help with all aspects of development and testing. This article explained you how to load your data properly and when and how to leverage the standard functionality that comes with SAP Commerce Cloud.

In summary, you should now be comfortable with:

  • Splitting data set for each stakeholder: developer, tester, and business team
  • Deployment this data in different environments: local, DEV, STAGE, and PROD
  • Migrating data from legacy systems to SAP Commerce Cloud
