ElasticSearch Connector for SAP Crystal Reports

Read / write ElasticSearch data inside your app; perform many ElasticSearch operations without coding, just use easy to use high performance API Connector for ElasticSearch

In this article you will learn how to quickly and efficiently integrate ElasticSearch data in SAP Crystal Reports without coding. We will use high-performance ElasticSearch Connector to easily connect to ElasticSearch and then access the data inside SAP Crystal Reports.

Let's follow the steps below to see how we can accomplish that!

Create ODBC Data Source (DSN) based on ZappySys API Driver

Step-by-step instructions

To get data from ElasticSearch using SAP Crystal Reports we first need to create a DSN (Data Source) which will access data from ElasticSearch. We will later be able to read data using SAP Crystal Reports. Perform these steps:

  1. Download and install ODBC PowerPack.

  2. Open ODBC Data Sources (x64):

    Open ODBC Data Source
  3. Create a User data source (User DSN) based on ZappySys API Driver

    ZappySys API Driver
    Create new User DSN for ZappySys API Driver
    • Create and use User DSN if the client application is run under a User Account. This is an ideal option in design-time, when developing a solution, e.g. in Visual Studio 2019. Use it for both type of applications - 64-bit and 32-bit.
    • Create and use System DSN if the client application is launched under a System Account, e.g. as a Windows Service. Usually, this is an ideal option to use in a production environment. Use ODBC Data Source Administrator (32-bit), instead of 64-bit version, if Windows Service is a 32-bit application.
  4. When the Configuration window appears give your data source a name if you haven't done that already, then select "ElasticSearch" from the list of Popular Connectors. If "ElasticSearch" is not present in the list, then click "Search Online" and download it. Then set the path to the location where you downloaded it. Finally, click Continue >> to proceed with configuring the DSN:

    ODBC DSN Template Selection
  5. Now it's time to configure the Connection Manager. Select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases, the default one is the right one). More info is available in the Authentication section.

    Steps how to get and use ElasticSearch credentials

    For Local / Hosted Instance by you

    1. Get your userid / password and enter on the connection UI

    For Managed Instance (By Bonsai search)

    If your instance is hosted by bonsai then perform these steps to get your credentials for API call
    1. Go to https://app.bonsai.io/clusters/{your-instance-id}/tokens
    2. Copy Access Key and Access Secret and enter on the connection UI. Click Test connection.
    3. If your Cluster has no data you can generate sample data by visiting this URL and click Add Sample Data https://{your-cluster-id}.apps.bonsaisearch.net/app/home#/tutorial_directory

    Fill in all required parameters and set optional parameters if needed:

    ElasticsearchDSN
    ElasticSearch
    Basic Authentication (UserId/Password) [Http]
    http://localhost:9200
    Optional Parameters
    User Name (or Access Key)
    Password (or Access Secret)
    Ignore certificate related errors
    ODBC DSN HTTP Connection Configuration

    Fill in all required parameters and set optional parameters if needed:

    ElasticsearchDSN
    ElasticSearch
    Windows Authentication (No Password) [Http]
    http://localhost:9200
    Optional Parameters
    Ignore certificate related errors
    ODBC DSN HTTP Connection Configuration

  6. Once the data source connection has been configured, it's time to configure the SQL query. Select the Preview tab and then click Query Builder button to configure the SQL query:

    Read / write ElasticSearch data inside your app; perform many ElasticSearch operations without coding, just use easy to use high performance API Connector for ElasticSearch
    ElasticsearchDSN
    Open Query Builder in API ODBC Driver to read and write data to REST API
  7. Start by selecting the Table or Endpoint you are interested in and then configure the parameters. This will generate a query that we will use in SAP Crystal Reports to retrieve data from ElasticSearch. Hit OK button to use this query in the next step.

    SELECT * FROM Indexes
    Configure table/endpoint parameters in ODBC data source based on API Driver
    Some parameters configured in this window will be passed to the ElasticSearch API, e.g. filtering parameters. It means that filtering will be done on the server side (instead of the client side), enabling you to get only the meaningful data much faster.
  8. Now hit Preview Data button to preview the data using the generated SQL query. If you are satisfied with the result, use this query in SAP Crystal Reports:

    ZappySys API Driver - ElasticSearch
    Read / write ElasticSearch data inside your app; perform many ElasticSearch operations without coding, just use easy to use high performance API Connector for ElasticSearch
    ElasticsearchDSN
    SELECT * FROM Indexes
    API ODBC Driver-based data source data preview
    You can also access data quickly from the tables dropdown by selecting <Select table>.
    A WHERE clause, LIMIT keyword will be performed on the client side, meaning that the whole result set will be retrieved from the ElasticSearch API first, and only then the filtering will be applied to the data. If possible, it is recommended to use parameters in Query Builder to filter the data on the server side (in ElasticSearch servers).
  9. Click OK to finish creating the data source.

Read data in SAP Crystal Reports from the ODBC data source

  1. First of all, open SAP Crystal Reports and create the new Crystal Report.
    Create New Crystal Report

  2. And it will open the new data source selection window. Under ODBC(RDO) double click on the Make New Connection and Select the desired ODBC DSN, in our case we need to select ElasticsearchDSN which we created in upper section. And Click on Next.

  5. That's it and you will be able to load the data in the Report.

Using ZappySys Driver Custom Views and Stored Procedure in SAP Crystal Report

You can create parameterized Stored Procedure and Virtual Tables on the same Data Source (ODBC DSN or Data Gateway Data Source). Please refer to this article for the same. You can create procedures to encapsulate custom logic and then only pass handful parameters rather than long SQL to execute your API call.

Using Custom Views in the SAP Crystal Report

After establishing the connection with ElasticsearchDSN Data Source you can use the custom view in SQL Crystal Report.

Using Custom Stored Procedure in the SAP Crystal Report

  1. First of all, create the custom stored procedure in the ZappySys Driver. Please refer to this article to create the custom stored procedure.
    ZappySys Driver Custom Stored Procedure
  2. After establishing the connection with ElasticsearchDSN Data Source you can use the custom Stored Procedure in SQL Crystal Report. Same way you can write custom queries also in the query box.

Conclusion

In this article we showed you how to connect to ElasticSearch in SAP Crystal Reports and integrate data without any coding, saving you time and effort. It's worth noting that ZappySys API Driver allows you to connect not only to ElasticSearch, but to any Java application that supports JDBC (just use a different JDBC driver and configure it appropriately).

We encourage you to download ElasticSearch Connector for SAP Crystal Reports and see how easy it is to use it for yourself or your team.
