Ignore that last response. Just skimmer and thought you didn't see any
problems in the trace.

Please respond to

The problem is probably not with SQL Trace, but more likely
my ability to read it. All it showed us is that in one occurence
of a query against a table, it used a bad index and took forever.
A second query used a better index and zoomed through. I cannot
tell why there is a difference.
Here's the bad one...
SELECT "SPTAG" , "WERKS" , "LGORT" , "SPART" , "PRDHA" , "MTART" , =
"MATNR" ,=20
"CHARG" , "BWART" , "BZEIT" , "BASME" , "MENGE"=20

What is the problem with SQLTrace so that you can't use it? There are
others ways of looking at this!
Anjo.
