I am using ESRI 10.1 suit (ArcGIS Desktop & ArcGIS Server, No ArcSDE) at my end and after running python script n number of times event layer converts into feature class.
Following steps I am following :
-I am using query layer in ArcMap & fetching records from MS sql server, table type is plane table.
-Created XY event source layer from query layer and displaying points on the map.
-layer is classified using unique value symbology.
-My query layer is updating five times in day and using python script (example2) to automate the unique value symbology (using windows scheduler) five times in day.
-Overwriting mxd on ArcGIS Server 10.1 using ArcPy in specific time interval.
-After 10 times my XY event source is automatically converts to feature class then I am not able to use ArcPy script to update the legend at my end
So is there any bug related to XY event source layer or am I doing something wrong??
Researching on Google and ArcGIS web help not getting any reason/limitation for that.
Any help will be great !! thanks in advance !!
