Oracle Forms Developer – Form Builder Reference, Volume 1

query string contains bind variable references which are local to A (:block.item or
:PARAMETER.param), when form A terminates execution, the global query record group is
converted to a global non-query record group (it retains the data, but a subsequent call to
POPULATE_GROUP is considered an error).
