000027 : The buffer table does not contain the buffer item
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.
Ensure that matching items exist in both the input coverage and buffer table.
