Validate Special Characters

Hello Experts,

This is File to Proxy Scenario.

We are getting Special Characters in some fields and PI is passing those values successfully. But we want to throw Error for that.

For Example:

Field Mobile Number should only contain numeric digit.

So we used pattern: [0-9], [0-9], [0-9], [0-9], [0-9], [0-9], [0-9], [0-9], [0-9], [0-9]

But still it is passing Special Characters.

Please help in this regard.

Regards,

Sayanti Mukherjee
