Eric,
Check with your DBAs the settings for the following DBSControl record field: MaxParTreeSegs. If they can set it to 128 or higher, you might be
able to use up to 64 WHEN clauses. I am not quite sure about that, though. The limit usually applies to the number of subqueries per SELECT. I am
guessing that it also applies to CASE and would appreciate your feedback if you decide to tune that parameter.
Regards,
Victor
