010358: No item has been merged.
Description
There was a problem when attempting to merge the attribute tables. To merge, it is necessary for both inputs to have a VAT. The merge can be done on a common attribute item between the two grids (default is VALUE) or with a lookup table that defines the relationship between the tables. If either attribute table or specified fields do not exist, the merge cannot be performed.
Solution
If either of the grids does not have an attribute table, use Build Raster Attribute Table to create them.
If you are not using the default merge field (VALUE), make sure that the fields you are using are present and of the correct type.
