"Map to field" is hiddent on Record producer vairable set variables.Issue If you go to a record producer - open a variable set and click on any variable - notice "map to field" is hidden. CauseExpected behaviorResolution Map to field cannot be used on a variable set variable. This is an expected behavior. Because, "map to field" can only be used on a record producer variable. It is true that you are using it for a record producer variable but since you created a variable set and trying to apply "map to field" to the variable which is part of a variable set - the "map to field" will be hidden. Since variable set can be used any where (for example on a catalog item). There is an OOB (out of box) client script called " map to field" running on "item_option_new" table will hide the map to field.
