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

Step-by-step instructions

To get data from XML File using SAP Crystal Reports we first need to create a DSN (Data Source) which will access data from XML File. 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):

   

3. Create a User data source (User DSN) based on ZappySys XML Driver:

   ZappySys XML 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. You can use pass single file or multiple file path using wildcard pattern in path and you can use select single file by clicking [...] path button or multiple file using wildcard pattern in path.
   

   Note: If you want to operation with multiple files then use wild card pattern as below 
   (when you use wild card pattern in source path then system will treat target path as folder regardless you end with slash)
   
   C:\SSIS\Test\reponse.xml (will read only single reponse.xml file)
   C:\SSIS\Test\j*.xml (all files starting with file name j)
   C:\SSIS\Test\*.xml (all files with .xml Extension and located under folder subfolder)
   

5. Now enter Path expression in Array Filter textbox to extract only specific part of XML file as below ($.feed.entry[*] will get content of entry attribute from XML document. Entry attribute is array of XML documents so we have to use [*] to indicate we want all records of that array)
   

   NOTE: Here, We are using our 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.
   $.feed.entry[*]
   

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

7. Click OK to finish creating the data source.

8. That's it; we are done. In a few clicks we configured the call to XML File using ZappySys XML File Connector.

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.

   

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 XmlFileDSN which we created in upper section. And Click on Next.

   XmlFileDSN

   

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.

   

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 XmlFileDSN 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.
   
2. After establishing the connection with XmlFileDSN 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.

Centralized data access via Data Gateway

In some situations, you may need to provide XML File data access to multiple users or services. Configuring the data source on a Data Gateway creates a single, centralized connection point for this purpose.

This configuration provides two primary advantages:

• Centralized data access
  The data source is configured once on the gateway, eliminating the need to set it up individually on each user's machine or application. This significantly simplifies the management process.
• Centralized access control
  Since all connections route through the gateway, access can be governed or revoked from a single location for all users.

	Data Gateway	Local ODBC data source
Simple configuration
Installation	Single machine	Per machine
Connectivity	Local and remote	Local only
Connections limit	Limited by License	Unlimited
Central data access
Central access control
More flexible cost

If you need any of these requirements, you will have to create a data source in Data Gateway to connect to XML File, and to create an ODBC data source to connect to Data Gateway in SAP Crystal Reports.

Let's not wait and get going!

Creating XML File data source in Gateway

In this section we will create a data source for XML File in Data Gateway. Let's follow these steps to accomplish that:

1. Search for gateway in Windows Start Menu and open ZappySys Data Gateway Configuration:

   

2. Go to Users tab and follow these steps to add a Data Gateway user:

   • Click Add button
   • In Login field enter username, e.g., john
   • Then enter a Password
   • Check Is Administrator checkbox
   • Click OK to save
   

3. Now we are ready to add a data source:

   • Click Add button
   • Give Datasource a name (have it handy for later)
   • Then select Native - ZappySys XML Driver
   • Finally, click OK
   XmlFileDSN

   ZappySys XML Driver

   

4. When the ZappySys XML Driver configuration window opens, configure the Data Source the same way you configured it in ODBC Data Sources (64-bit), in the beginning of this article.

5. Very important step. Now, after creating or modifying the data source make sure you:

   • Click the Save button to persist your changes.
   • Hit Yes, once asked if you want to restart the Data Gateway service.

   This will ensure all changes are properly applied:

   
   Skipping this step may result in the new settings not taking effect and, therefore you will not be able to connect to the data source.

Creating ODBC data source for Data Gateway

In this part we will create ODBC data source to connect to Data Gateway from SAP Crystal Reports. To achieve that, let's perform these steps:

1. Open ODBC Data Sources (x64):

   

2. Create a User data source (User DSN) based on ODBC Driver 17 for SQL Server:

   ODBC Driver 17 for SQL Server

   
   If you don't see ODBC Driver 17 for SQL Server driver in the list, choose a similar version driver.

3. Then set a Name of the data source (e.g. Gateway) and the address of the Data Gateway:

   GatewayDSN

   localhost,5000

   
   Make sure you separate the hostname and port with a comma, e.g. localhost,5000.

4. Proceed with authentication part:

   • Select SQL Server authentication
   • In Login ID field enter the user name you used in Data Gateway, e.g., john
   • Set Password to the one you configured in Data Gateway
   

5. Then set the default database property to XmlFileDSN (the one we used in Data Gateway):

   XmlFileDSN

   

6. Continue by checking Trust server certificate option:

   

7. Once you do that, test the connection:

   

8. If connection is successful, everything is good:

   

9. Done!

We are ready to move to the final step. Let's do it!

Accessing data in SAP Crystal Reports via Data Gateway

Finally, we are ready to read data from XML File in SAP Crystal Reports via Data Gateway. Follow these final steps:

1. Go back to SAP Crystal Reports.

2. First of all, open SAP Crystal Reports and create the new Crystal Report.

   

3. 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 GatewayDSN which we created in upper section. And Click on Next.

   GatewayDSN

   

4. Read the data the same way we discussed at the beginning of this article.

5. That's it!

Now you can connect to XML File data in SAP Crystal Reports via the Data Gateway.
