Description
The buffer item should be in both the input coverage and buffer able. The buffer table is an INFO lookup table that uses a buffer distance for each buffer item. A buffer table can be used successfully if the buffer table and input coverage contain the same buffer item. The buffer table must contain at least two columns: the buffer item, which also exists in the input coverage's attribute table with the same item definition; and a numeric DIST item, which is used to provide the buffer distances.
Solution
Ensure that matching items exist in both the input coverage and buffer table.
