Hi Naga_Rajan,
use matches activity and pass β[200]{3}(\d{7})β this expression in pattern property.
(it will give 10 digit number only starting with 200)
matchesActivityOutput(0).value β give matching recordMain.xaml (6.7 KB)
The regular expression should be β\b200\d{7}\bβ. It will extract any 10 digits number starting with 200. It wonβt match if the number starts with 200 but are longer than 10 digits or contains letters.
