Hi @Mohammed Rizwan, 

As per you question In outsystems built in function for format currency 

FormatCurrency(87.63, "$", 2, ".", ",")

use this function.

To create a function for formatting currency in Euros within OutSystems, follow these steps:

1. Define the Client Action: Create a action named FormatEuro. This action will centralize the currency formatting logic.

2. Input and Output Parameters:

   • Input: The action should accept a monetary value as input.
   • Output: The action should return the formatted currency string.

3. Implement the Logic:

   • Use the FormatCurrency function to convert the input value to a Euro currency format. For example:

     FormatCurrency(In, "€", 2, ".", ",")

4. Centralize Configuration: By centralizing the formatting logic in a server action, any changes to the formatting can be made in one place. This ensures consistency across the application and simplifies maintenance.

5. Activate the Function Client Action: Ensure the action is callable from various parts of your application. 

6. Example Usage:

   • Instead of directly formatting currency in multiple places, call the FormatEuro client action:

     
     

     By following these steps, you ensure that any adjustments to the currency formatting logic are applied universally, avoiding the need to update multiple instances throughout your codebase.
