replaceDataSource

I have mxd i work on for different cases, but have the the same layers. The script i am working on needs to update the "Subject_Property" layer data source. I am having trouble getting this to work.

The script will search for a text in the "DXF_TEXT" filed and export it out to the location of the mxd. The mxd already has the layer "SUBJECT_PROPERTY" but i need to get it to update the mxd's "SUBJECT_PROPERTY" with the one that was searched and exported, don't needed added to the current mxd. hopefully this makes sense.

Here is the code i have so far. Any help would be gratefully appreciated.
Thanks.

import arcpy, string, os

arcpy.env.overwriteOutput = True
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
lyr = arcpy.mapping.ListLayers(mxd, "TAXLOTS")[0]

arcpy.env.workspace = os.path.dirname(mxd.filePath)
wp = os.path.dirname(mxd.filePath)



value = arcpy.GetParameterAsText(0)
if value == "#" or value == "":
    value = None
if value:
    arcpy.SelectLayerByAttribute_management(lyr, "NEW_SELECTION", "\"DXF_TEXT\" = '" + str(value) +"'")
else:
    arcpy.AddError("no value")
    
df.extent = lyr.getSelectedExtent()
df.scale = 7000



if int(arcpy.GetCount_management("TAXLOTS").getOutput(0)) > 0:

   arcpy.Select_analysis("TAXLOTS", "SUBJECT_PROPERTY")

#del mxd
#mxd = arcpy.mapping.MapDocument("CURRENT")
#lyr = arcpy.mapping.ListLayers(mxd, "SUBJECT_PROPERTY")[0]
lyrpath = lyr.workspacePath
data_path = os.path.dirname(lyrpath)

SP = "SUBJECT_PROPERTY" 
lyr.replaceDataSource(data_path, "SHAPEFILE_WORKSPACE", SP, True )

I have something that works but i am not sure if this is correct or if there is an easier way of doing this.
Any input would be gratefully appreciated please.

import arcpy, string, os

arcpy.env.overwriteOutput = True
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
lyr = arcpy.mapping.ListLayers(mxd, "TAXLOTS")[0]

arcpy.env.workspace = os.path.dirname(mxd.filePath)
wp = os.path.dirname(mxd.filePath)



value = arcpy.GetParameterAsText(0)
if value == "#" or value == "":
    value = None
if value:
    arcpy.SelectLayerByAttribute_management(lyr, "NEW_SELECTION", "\"DXF_TEXT\" = '" + str(value) +"'")
else:
    arcpy.AddError("no value")
    
df.extent = lyr.getSelectedExtent()
df.scale = 24000



if int(arcpy.GetCount_management("TAXLOTS").getOutput(0)) > 0:

   arcpy.Select_analysis("TAXLOTS", "SUBJECT_PROPERTY")

del mxd, wp, 
mxd = arcpy.mapping.MapDocument("CURRENT")
lyr = arcpy.mapping.ListLayers(mxd, "SUBJECT_PROPERTY")[0]
lyrpath = lyr.workspacePath
#data_path = os.path.dirname(lyrpath)
wp = os.path.dirname(mxd.filePath)

SP = "SUBJECT_PROPERTY" 
lyr.replaceDataSource(wp, "SHAPEFILE_WORKSPACE", SP, True )

arcpy.RefreshActiveView()
arcpy.RefreshTOC()

I'm not clear about your concern (if it is working). As long as your wp variable is pointing to the correct location, you have the workspace type correct and you have a valid data source, it should just work.
