lookup on null field giving warning

[saidvs]

hi..

when doing a lookup on a nullable field, I am getting the following error..

When binding output schema variable "outRec": When binding output interface field "XXXX" to field "XXXX": Converting a nullable source to a non-nullable result;
a fatal runtime error could occur; use the modify operator to
specify a value to which the null should be converted.

Can you give me suggestions how to get rid of the warning...

Thanks,
Venkat

It is giving error because you are sending the column with out handling its null values.Either use IsNull() or NulltoEmpty() in the transformer stage or handle_null() in the modify stage for that particular field before doing lookup.
