Since 10.0 SP4 (until 10.1 SP1) i can't use arcpy.CopyRows_management or arcpy.CopyFeatures_managementwith fieldnames that exceeds 28 characters. These fieldname were change. Here some examples:
aaaaaaaaaaaaaaaaaaaaaaaaaa28 aaaaaaaaaaaaaaaaaaaaaaaaaa28 everything OK
aaaaaaaaaaaaaaaaaaaaaaaaaaa29 aaaaaaaaaaaaaaaaaaaaaaaaaaa2_20 wrong name
aaaaaaaaaaaaaaaaaaaaaaaaaaaa30 aaaaaaaaaaaaaaaaaaaaaaaaaaaa_21 wrong name
aaaaaaaaaaaaaaaaaaaaaaaaaaaaa31 aaaaaaaaaaaaaaaaaaaaaaaaaaaaa_22 wrong name
The number after the underscore seems to be the field-id.FGDB to FGDB works but FGDB to ArcSDE (on SQL Server) doesn't!Copy the data with ArcCatalog works.Is this a known bug?Is there a workaround or patch?
