System Response

A warning is given since no non-transparent matchcode IDs should be
created for this matchcode object. This is because the matchcode data
cannot be built because the key is too long.

Do not define non-transparent matchcode IDs.
Create a search help that operates on a suitable database view instead.

corresponding constant is also used in the R/3 kernel.
