SSIS Parent Child Package Configuration

In this article, we will show you how to create an SSIS Parent Child Package Configuration with example. We already explained the list of Package Configurations in our previous article. So, please refer to the Package Configuration to understand the same.

We have SSIS File System Task Folder inside our D drive, and it has four text files. To demonstrate this SSIS Parent Child Package configuration, we will load data from text files to the SQL Server table. The following screenshot will show you the data inside the Employee1.txt file.

Text File 1

The following screenshot shows the data inside the Employee2.txt file.

Text File 2

The below screenshot shows the data inside the Employee3.txt file.

Employee Text File 3

The following screenshot shows you the data inside the Employee4.txt file.

Example for SSIS Parent Child Package Configuration

In this SSIS example, first, we will configure the Parent Package, the next child package. Then we will create a Parent package variable (package configuration). And our goal to access the Parent Package variable (with data) from the child package

Configure Parent Package in SSIS

In this package, we will enumerate those Employee text files, and save the file names in a string variable. To do so, First Drag and drop the Foreach Loop Container into the Control Flow region

Parent Package Configuration

Double click on it will open the Foreach Loop Editor to configure it. Within the Collections tab, Please select Foreach File Enumerator because we want to loop over the files present in our file system. Next, click on the Browse button to select the folder name from our file system.

Foreach Loop Container Editor

From the below screenshot, you can see, we are selecting the FILE SYSTEM TASK FOLDER folder in our D Drive. Within the Files section, we are using Wildcard *.txt because we want to enumerate text files

Select txt files in Enumerator Configuration

Our goal to store the file names in a variable. To do that, go to the Variable Mappings section and select the variable and assign it to index 0. Once you complete, Click OK to finish configuring the Foreach Loop Container.

But we intend to load all the text files (Employee1, Employee2, Employee3, and Employee4) present in the file system to the table. For this, Please select the Flat File Connection Manager from the Connection Managers pane and right-click on it to choose the Properties option from the Context menu.
