Hi,

The following blog contains your full solution:

[https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/5479] [original link is broken] [original link is broken] [original link is broken];

In the udf ThrowException in the blog just give the validating condition of the date as you wish and IF the condition doesn't satisfy write the statement

ExceptionThrower.fire("Validation of date failed.");

by using this UDF in your graphical mapping you will be able to throw a Runtime Exception.

Hi,

Yes u can do it in UDF.

1) By using If-Else check your date validation.

2) Use two input in UDF 1st is date 2nd one constant which u want to validate.

3) Use RemoveContext before UDF

4) To throw an exception use any java function and give wrong input to it.

e.g. Use Substring to detect 10 characters and send blank input. this will throw exception.
