Hi,

Lookup_7,0: When binding input interface field "Column1" to field "Column1": Converting a nullable source to a non-nullable result;
a fatal runtime error could occur;
use a modify operator to specify the value to which the null should be converted.

How to solve the above issue.

Thanks,

you need to perform nul lhandling .This is very common warning message .

Nullability is getting changed in the lookup .

Well... if "use a modify operator" isn't the way you want to go, do an exact search on your message starting with "Converting" and see if that helps.
