break if field has value assigned()

This function can only be used on fields within a node having value "Loop" in node attribute " Iteration" set and only makes sense for option normal data mapper (in "Phase2/Extended").

Aborts the value assignment (mapping process/function execution) for this field if it already had a value assigned in a preceding iteration (by the mapping or a function), otherwise, "false" is returned. Note: If an empty string ("") has been assigned to the field, it is considered to be an assigned value. The Empty Flag has no relevance for this function.

This function has no parameters.
