Access your legacy ERP (Enterprise Resource Planning) system using ERP Canvas and identify customizations with ERP Customization Mining (ERP-CM). You can then use additional Now Platform apps, such as App Engine Studio (AES) and Flow Designer to organize and replatform ERP data.
Replatforming is the process of scanning legacy ERP system code to find potential candidates to move onto your Now Platform instance as new apps. You can use data from the ERP system as a source for apps built on the Now Platform, improving performance, enhancing security, and reducing maintenance.
Combined benefits of integrating ERP Canvas and ERP-CM to replatform apps
Legacy systems of records, such as SAP, can have old, complex custom code and data that require more time and effort to move to newer versions of the system of record. Use ERP Canvas and ERP-CM to scan the system of record to find and replace custom code with digitized workflows, resulting in a clean ERP core.

The replatforming of legacy code enables rapid innovation on top of the system of record without knowledge of the legacy system. Database administrators and developers are then relieved of time-consuming efforts to create database views or endpoints in the system of record, freeing them to work on other projects, such as migration.
Replatformed data is immediately available, mirrored in easy-to-manage tables and apps. Users no longer need to request information from database administrators, which can take weeks. Replatformed apps use the ERP system of record as the live data source.
Workflow for ERP Canvas and ERP-CM
- Have your administrator use the Connections and Credentials app to configure credentials to connect ERP Canvas to the ERP system of record. For more information, see Connections and Credentials.
- Create an ERP system in ERP Canvas using the connection and credentials alias that you configured. For more information, see Create an ERP system in ERP Canvas.
- In ERP Canvas, build your ERP systems, ERP models, and tables in a development instance.
- Create or clone an ERP model that scans the specified ERP module in the system of record for available tables and fields. Note the tables and fields in the ERP model for use in extraction and remote tables. For more information, see Clone an ERP model in ERP Canvas.
- Add new tables, fields, and join conditions to include additional data in the ERP model. Note:For more information, see:You can use a combination of remote tables and extraction tables to retrieve data from your legacy ERP system.
- Remote tables get their records from running an associated script against an external data source, and have a limit of 1,000 records.
- Extraction tables retrieve large amounts of data once a day using a scheduled query, and use transform tables to process data for use on the Now Platform.
- Build and customize remote tables to make them available for use as a data source, such as when building apps in App Engine Studio. For more information, see:
- Work with ETL extraction tables to regularly scan the system of record and extract data to a staging table.
- Create as many separate extraction tables as needed, such as one for each supported country. For more information, see Extracting and transforming data in ERP Canvas.
- You must first create the table transform map that connects the source table (on the system of record) to a Glide table on the Now Platform. For more information on creating table transform maps, see Create a transform map.
- Extraction processes are configured in the ServiceNow app that uses them. For example Flow Designer.
- After the extraction process is run, use import sets to map imported data into Now Platform tables. For more information, see Import sets.
- Identify legacy ERP system customizations to modernize and replatform with ERP-CM.
- Move the ERP Canvas systems, ERP models, and tables to a production environment when they are ready. For more information, see Managing ERP development pipelines in ERP Canvas.
- Meet with a customer and agree to run an analysis with ERP Customization Mining on their ERP system of record.
- Connect the customer ERP system of record to the ServiceNow instance using ERP Canvas. Note: Most customers have their own instance.
ERP-CM uses the system connections configured in ERP Canvas. For more information, see Working with ERP systems in ERP Canvas.
- Use ERP Canvas to build ERP models from fields on the available remote tables as specified in previous workflow steps.
- Run ERP Customization Mining to find candidates. Candidates are custom code in the system of record that you can replace with ServiceNow apps. For more information, see Browse an overview of candidates in ERP-CM.
- Choose candidates to replatform. For more information, see Save potential candidates to replatform.
- Use the candidate details in ERP-CM as a central place to enter comments and save attachments relating to the candidate. For more information, see View and work with candidate details in ERP-CM.
- In the candidate details, identify any similar candidates that you could combine into a single replatformed app. For more information, see How ERP-CM determines score and potential for replatforming candidates.
- Return to ERP Canvas to continue building data models with remote tables and extraction tables. Ensure that all the necessary data is available in the Now Platform. For more information, see Building ERP models to work with ERP data.
- Use the ERP data that is now available as the data source when building apps on the Now Platform, such as:
- App Engine Studio: For more information, see Create a data model for your application.
- Flow Designer: For more information, see Flow DesignerWorkflow Studio data.
- Table Builder: For more information, see Data in Table Builder.
- UI Builder: For more information, see Dynamically expose data in UI Builder pages (advanced feature).
- Workspace Builder: For more information, see Configure a record page for a workspace in Workspace Builder.
- Measure and monitor the performance of the new app using applicable metrics and parameters with your preferred analytic tools.
