I am more concerned about other messages than just the SU
table issue. The 31DEC06 version should be rather faster than the
31DEC05, not grossly slower. Do you have the times when the messages
appeared?
Furthermore, essential columns should not be missing from AT and CL
tables. Can you send me a PRTAB of the tables? The table routines
only need a couple of very basic columns so the fact that there is one
IF not two should not matter. Note too that we tested this a lot so I
may need your data if we are to debug the problem you have hit.
