Changes in the Datatype

Hi,

Scenario : Webservice -> XI -> JDBC or any scenaio

I have to pass a mandatory integer datatype input as per the <b>latest</b> changes, but my old Sender client(To send the request value to XI) has the old code so it can pass only String or other than integer datatypes.. What all errors we have to face for this case?

Note: The old sender client is not updated with the latest changes. In future also we don't want to update it.

Regards

Sara
