I have a layer file which has a group layer. The group layer has two sub layers, one is a normal SDE feature class, the other is a SDE annotation feature class. My intention is to change the data source of both feature class layers. I have no problem using arcpy to change the data source for the normal feature class, but arcpy treats the annotation class as a group layer, and I am not able to see or change its data source. I am using ArcgIS 10.0. The follow code always gives :"can not describe ... layername" on the annotation layer on desc = arcpy.Describe(lyr).
lyrfile = r"C:\Users\guana\AGS100LayerFiles\Lease_License\Non Nexen Lease - Lexco.lyr"
target_wspace = r"L:\GIS\GIS_Services\sso@usqa06.sde"
# where to save the layer files
savedir = r"C:\Users\guana\AGS100LayerFiles\SSO_QA\Lease_License"
layer = arcpy.mapping.Layer(lyrfile)
for lyr in arcpy.mapping.ListLayers(layer):
hasDataSource = False
if not lyr.isGroupLayer:
print "Normal layer %s" % (lyr.longName)
if lyr.supports("DATASOURCE"):
hasDataSource = True
#print lyr.dataSource
dest_fname = os.path.join(savedir, lyr.longName)
else:
print "%s is a group layer " % (lyr.name)
dest_fname = os.path.join(savedir, lyr.name)
# see it is an annotation featuer class
try:
desc = arcpy.Describe(lyr)
if desc.dataElement.dataType == "FeatureClass":
if (desc.featureType in ["Annotation","CoverageAnnotation"]):
print "%s is an annotation layer: dataSource = %s" % (lyr.name, lyr.dataSource)
hasDataSource = True
except:
print "can not describe " + lyr.name
Running this on the annotation feature class always fails:
lyr.replaceDataSource(target_wspace, 'SDE_WORKSPACE', lyr.datasetName, True)
Any help is greatly apprciated.
