@Raja.G You can use Arrlist.Append(“fff”) You would have to use it in an Assign Activity in this way : Arrlist = Arrlist.Append(“fff”).ToArray ---

Hi @Raja.G As per i know Array is of static length. So how can new variable be added to that array ? I will suggest that make it as list and then add the string to the same list and then convert that list to array. Happy Automation 🙌 Best Regards Er Pratik Wavhal 🤖👨🏽‍💻 💻 ---

@Raja.G Can you use that Input Dialog Activity After If Condition Activity and Check? If you want to Save the Updated Array each time you run the workflow then you would need it to be updated in a text file or Excel file. Then we can retrieve each time the contents from Excel and pass it as Array to the Input Dialog. In that way you can be able to See the Updated Input Dialog everytime you’ll be able or it is not possible to do so 😅 ---
