ArcGIS error: Unable to save edits. Raster dataset already exists

ArcGIS error: Unable to save edits. Raster dataset already exists


When I edit my attribute table then try to save edits an error message appears on my screen: "Unable to save edits. Raster dataset already exist." Why does this error message appear?

My table of contents contains one feature class named "Buildings". Buildings have a lot of fields - building name (text), floor number (integer), picture of building (raster), etc. and their capacity about 100gb.

Until Thursday I have edited the attribute table and saved correctly but suddenly I received the above error message on Sunday. I edited some polygons without raster and saved without problem. However I try to edit polygons which contain a raster and then I want to save edits, but the error message does not let me.


The only way i found for it to work is to remove the raster data. Save it. Make the changes you want. Save it. Than add the raster data back and save it again. I know this sounds like a hassle but this is the only way i know for it to work. I am sure there is an easier way i just don't know what it is.
