Can we use target.field in source script?

[SD40]

I have a requirement that is- 

If the target field value is empty then only return the source.field value to the target field.

Hi,

you can try to access it; if it doesn't work then don't use field map for that target field

instead use onBefore transform script

if(target.fieldName.nil()){

target.fieldName = source.u_fieldName;

}

Hi ED,

For None the backend value is blank so you can mention

if(target.custom_field==''){

target.custom_field=source.field;

}
