I don't see anything wrong with your code.  I ran it on some MXDs and it worked as expected. I did have to modify it because it would not run by itself.  Layer.longName returns the layer name preceeded by its group layer name (if it exists). Here is the code I ran: import arcpy from arcpy.mapping import *  #Brings in entire functionality of the mapping module  mxd = MapDocument(r"C:\Temp\Test.mxd")  TOClayers = ListLayers(mxd) for layer in TOClayers:     print "Layer LongName is : " + layer.longName     print "Layer name is : " + layer.name  print"\nStart the dataframe loop." dataframes = ListDataFrames(mxd) for frame in dataframes:     layers = ListLayers(mxd, '', frame)     for layer in layers:         print '\nData Frame : ' + frame.name +'\tLayer longName ' + ': ' + layer.longName         print 'Data Frame : ' + frame.name +'\tLayer Name ' + ': ' + layer.name Jeff ...

My bad, I wrote that help topic.  I don't know how else to word it.  When you create an SDE connection file, an actual file gets persisted on disk as a .sde file, but the connection information persists "in memory" allowing you to make the connection to SDE.  This technique is useful for managing map documents that contain layers that require logins. The 4th sample on the arcpy.mapping.MapDocument object uses this: http://resources.arcgis.com/en/help/main/10.1/#/MapDocument/00s30000000n000000/ Another sample that uses this technique is the 3rd sample on the layer class for arcpy.mapping: http://resources.arcgis.com/en/help/main/10.1/#/Layer/00s300000008000000/ You can remove the temporary file at the end of the script.

My motto has always been, "why do it in the UI, when you can do it with arcpy".  Everything you can do with DDP, you can do with arcpy.mapping plus a whole lot more. Couple of things: 1) Curious why mxd = arcpy.mapping.MapDocument(mxd = "CURRENT") works.  The parameter name is mxd_path (but that doesn't work).  I personally use .MapDocument("CURRENT") 2) Your Layer variable doesn't look right.  Try, Layer = arcpy.mapping.ListLayers(mxd, "ImplausibleReads", df)[0] Jeff ...
