000813: The value is not a valid field map.


The parameter value used is not a field map. A field map provides a field definition and a list of input fields from a set of tables or feature classes that provide its values.


Update the field map parameter value. When entering the field map value as text, the syntax must be valid: "fldName newFldName visible;fldName1 newFldName1 visible1;…;fldNameN newFldNameN visibleN". Refer to Mapping fields to learn more about field mapping in scripts.
