In a new app I am appending a table ctreated in VFP 9.0SP1 to a table created in VFP 8.0. I get an error (Error building key for "table name" tag "tag name". Error 2199.

The table structures are exactly the same, same # of fields, same field lengths, and same field attributes. The table created in VFP 9.0SP1 has no indeces, however.

Are there compatabliity issues between the two versions? BTW, there are no memo fields in either table.

Thanks in advance for any suggestions.
