000049: Failed to build attribute table.

泽军霍 — Mon, 12 Aug 2024 08:04:33 GMT

I encountered an error message while executing the 'Build raster attribute table' for my dataset“
000049: Failed to build attribute table.”， But I have checked that my dataset is an unsigned integer 32-bit, and it is a single band. Why does it still report an error? The weirdest thing is that I have already created one, but the others are still reporting errors. I don't know why this raster dataset doesn't report errors. I suspect that my table records too much information, so it reports an error

Hi @泽军霍

Can you try the following steps to see if this has worked for you?

After creating the multidimensional mosaic dataset and adding the rasters to the mosaic, add the mosaic to the map
Right click on the mosaic dataset and select "Data" then "Export Raster"
- In the Export Raster options, please specify the following:
  - Verify the pixel type is an integer (this should match up with the mosaic dataset)
    - This tool will not run if the pixel type is floating point or double precision.
  - For Output Format, specify "CRF"
  - The rest of the options can be left as default, and run the tool
Run "Build Raster Attribute Table" on the resulting raster layer from the export
- After running "Build Raster Attribute Table", please remove the raster and re-add it to the map to view the attribute table

Here is the article that is related to the error you are getting

This error is present due to how the multidimensional raster was created.

Thank you very much for your reply！ My dataset is not a multidimensional raster. Just now, I created unique values in the symbol system in ArcGIS software, and it showed that the number of my unique values exceeded the default limit (>65536). Is this the reason? Do you have some better advice, because I need to create a property table for my subsequent work.
