     Lossless

     Only source items that have a type that can be converted without loss of data to the target item type are presented as mapping candidates.

     Lossy

     (Default) Only source items that have a type that can be converted to the target item type without causing a possible runtime error are presented as mapping candidates.

   • Select Map optional primitive data types to automatically map primitive data types that are optional.
