Microsoft’s Power Automate platform is making RPA (Robotic Process Automation) more accessible to a wider range of users than ever before. Key to leveraging this powerful technology is understanding how to implement data objects in desktop flows, an essential topic for those preparing for the PL-500 Microsoft Power Automate RPA Developer exam.
Understanding Data Objects in Desktop Flows
In desktop flows, data objects act as a container for various types of data. They can be considered analogues to variables in traditional programming, helping to structure data, and are essential for any process that requires data to be saved, manipulated, or passed between steps.
In the context of Power Automate, you get to work with three types of data objects termed as Input, Output, and Error information.
- Input: These data objects are used to pass information from one action to another within the flow.
- Output: These types of data objects are used to capture and extract information after an action has been performed.
- Error information: This data object is particularly useful for debugging and error handling, as it details any problems encountered during the flow’s run.
Implementing Data Objects
The implementation of data objects in your desktop flows typically involves three main steps: defining the data objects, initializing them, and then using the data objects in your flow actions.
- Define the Data Object: This involves specifying the required data object by selecting the data type of the data object. Data types include numbers, text, boolean, table, and record, among others.
- Initialize the Data Object: After defining the data objects, you need to initialize them by setting their initial values. This is important as it allows the flow to have something to reference when first using the data object.
- Use the Data Object in Actions: Once the data object is defined and initialized, you can use it within the flow actions to collect, store, analyze, and manipulate data.
Example: Data Objects in Desktop Flows
Suppose you want to create a desktop flow that performs a scan on a set of files in a folder and counts how many .txt files there are. For this task, you might define and use data objects as follows:
- Define the Data Object: Create a Number data object called “TextFileCount”.
- Initialize the Data Object: Initialize “TextFileCount” to 0. It will start at zero and increment each time the flow finds a .txt file.
- Use the Data Object in Actions: In this case, you could use the “List files in a folder” action to scan the input folder, then use a condition action to look at each file’s extension. If the extension matches “.txt”, you increment “TextFileCount” by 1.
- Output Data Object: After the scanning operation ends, you could output the value of “TextFileCount” to denote the number of .txt files found in the directory.
Key Takeaways
Understanding and implementing data objects is a crucial skill for anyone aspiring to become a proficient power automate RPA developer. Utilizing these strategies can help your automation process become more efficient, effective, and error-free.
