Hi, We can use the below function.

Substring(String StringToUse, int StartIndex) 

• StringToUse: This is the string from which you want to extract a substring. 

• StartIndex: This specifies the index from which the substring will start. The index is typically zero-based, so the first character of the string is at index 0. 

Hi @TejaswiP16741492,

Approach:

1. Convert to String: Ensure the input (e.g., a number or numeric string) is treated as a string.
2. Calculate Start Position: Use the string’s length minus the number of digits you want to extract.
3. Extract Substring: Use substring function to get the desired portion.

Function Example:

Suppose you have a property .NumericString (e.g., "123456789") and want to extract the last 3 digits (result: "789"). Here’s how you can write it in a Pega expression (e.g., in a data transform ):
