SAP Crystal Reports JSON Connector

In this article you will learn, how to integrate JSON data to SAP Crystal Reports without coding in few clicks (Live / Bi-directional connection to JSON). JSON Connector can be used to extract and output JSON data stored in local JSON files, JSON data coming from REST API web service calls (Web URL) or direct JSON String (variables or DB columns). JSON Connector also supports JSONPath to filter data from nested array/sub-documents. This Connector is optimized to work with very large files.

Using JSON API Connector you will be able to connect, read and write data from within SAP Crystal Reports. Let's take a look at the steps below to see how exactly to accomplish that.

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

To get data from Json using SAP Crystal Reports we first need to create a DSN - Data Source - which will access data from Json, which later will be able to get using SAP Crystal Reports. Perform these steps:

  1. Install ZappySys ODBC PowerPack.

  2. Open ODBC Data Sources (x64):
    Open ODBC Data Source

  3. Create a User Data Source (User DSN) based on ZappySys JSON Driver:

    Create new JSON Driver

    You should create System DSN if client application is launched under Windows System Account, e.g. as a Windows Service.
    Launch ODBC Data Sources 32-bit version in case your client application is a 32-bit (x86) application (required only for System DSN).
  4. Select Url or File and paste the following Url for this example.
    NOTE: Here for demo, I'm using odata API, but you need to refer your own API documentation and based on that you need to use your own API URL and need to configure connection based on API Authentication type

  5. Now enter JSONPath expression in Array Filter textbox to extract only specific part of JSON file as below ($.value[*] will get content of value attribute from JSON document. Value attribute is array of JSON documents so we have to use [*] to indicate we want all records of that array)
    NOTE: Here, I'm using my desired filter, but you need to select your desired filter based on your requirement.
    Click on Test Connection button to view whether the Test Connection is SUCCESSFUL or Not.

  6. Once you configured a data source, you can preview data. Hit Preview tab, and use similar settings to preview data:
    ZappySys ODBC Driver - Preview JSON Driver

  7. 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 JsonDSN which we created in upper section. And Click on Next.

    SAP Crystal Report - Select ODBC JsonDSN DSN

  3. Expand the Connection and under the data select the desired table(s) or view(s) and click Add > button and click on Next.

  4. Add the desired Fields to Display in the Reports. Here we are adding all fields and click on Finish.
    SAP Crystal Report - Add Display Fields

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

Using ZappySys Driver Custom Views and Store 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 JsonDSN Data Source you can use the custom view in SQL Crystal Report.

Using Custom Store Procedure in the SAP Crystal Report

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

Create Custom Store Procedure in ZappySys Driver

You can create procedures to encapsulate custom logic and then only pass handful parameters rather than long SQL to execute your API call.

Steps to create Custom Store Procedure in ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here

  1. Go to Custom Objects Tab and Click on Add button and Select Add Procedure:
    ZappySys Driver - Add Store Procedure

  2. Enter the desired Procedure name and click on OK:
    ZappySys Driver - Add Store Procedure Name

  3. Select the created Store Procedure and write the your desired store procedure and Save it and it will create the custom store procedure in the ZappySys Driver:
    Here is an example stored procedure for ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here

    CREATE PROCEDURE [usp_get_orders]
    @fromdate = '<<yyyy-MM-dd,FUN_TODAY>>'
    AS
    SELECT * FROM Orders where OrderDate >= '<@fromdate>'

    ZappySys Driver - Create Custom Store Procedure

  4. That's it now go to Preview Tab and Execute your Store Procedure using Exec Command. In this example it will extract the orders from the date 1996-01-01:

    Exec usp_get_orders '1996-01-01'

Create Custom Virtual Table in ZappySys Driver

ZappySys API Drivers support flexible Query language so you can override Default Properties you configured on Data Source such as URL, Body. This way you don't have to create multiple Data Sources if you like to read data from multiple EndPoints. However not every application support supplying custom SQL to driver so you can only select Table from list returned from driver.

Many applications like MS Access, Informatica Designer wont give you option to specify custom SQL when you import Objects. In such case Virtual Table is very useful. You can create many Virtual Tables on the same Data Source (e.g. If you have 50 URLs with slight variations you can create virtual tables with just URL as Parameter setting.

  1. Go to Custom Objects Tab and Click on Add button and Select Add Table:
    ZappySys Driver - Add Table

  2. Enter the desired Table name and click on OK:
    ZappySys Driver - Add Table Name

  3. And it will open the New Query Window Click on Cancel to close that window and go to Custom Objects Tab.

  4. Select the created table, Select Text Type AS SQL and write the your desired SQL Query and Save it and it will create the custom table in the ZappySys Driver:
    Here is an example SQL query for ZappySys Driver. You can insert Placeholders also. Read more about placeholders here

    SELECT
    "ShipCountry",
    "OrderID",
    "CustomerID",
    "EmployeeID",
    "OrderDate",
    "RequiredDate",
    "ShippedDate",
    "ShipVia",
    "Freight",
    "ShipName",
    "ShipAddress",
    "ShipCity",
    "ShipRegion",
    "ShipPostalCode"
    FROM "Orders"
    Where "ShipCountry"='USA'

    ZappySys Driver - Create Custom Table

  5. That's it now go to Preview Tab and Execute your custom virtual table query. In this example it will extract the orders for the USA Shipping Country only:

    SELECT * FROM "vt__usa_orders_only"
