The Field Map parameter in the Append tool does not recognize the matching fields of a layer with editor tracking enabled in ArcGIS Pro.

Additional Information

Workaround

The following Python script works to enable the editor tracking fields to be append and match the source dataset:

######################################

import arcpy

source = <link to source data>

target = <link to target data>

arcpy.env.preserveGlobalIds = True # can comment out this line if data does not have GlobalIds or if do not wish to preserve GlobalIds

arcpy.TruncateTable_management(target)

myFieldMappings = arcpy.FieldMappings()

myFieldMappings.addTable(target)

for fmi in range(myFieldMappings.fieldCount):

fm = myFieldMappings.getFieldMap(fmi)

 for targetfield_index in range(fm.inputFieldCount):

  intable = fm.getInputTableName(targetfield_index)

  if intable == arcpy.Describe(target).catalogPath:

fm.removeInputField(targetfield_index)

   myFieldMappings.replaceFieldMap(fmi, fm)

   break

for fmi in range(myFieldMappings.fieldCount):

fm = myFieldMappings.getFieldMap(fmi)

 targetFieldName = fm.outputField.name

 sourceFieldList = arcpy.ListFields(source,targetFieldName)

 for f in sourceFieldList:

 if (len(sourceFieldList)) > 0:

  sourceField = sourceFieldList[0]

  newFMap = arcpy.FieldMap()

 newFMap.addInputField(source,sourceField.name)

  myFieldMappings.replaceFieldMap(fmi, newFMap)

arcpy.Append_management(source, target, "NO_TEST", myFieldMappings)
