#-- We cannot execute this test as dmlproc locks the table in the first command,
#-- so when cpimport is invoked by LDI, it fails because it cannot get lock on the table.

#-- LDI, DML, rollback
#-- As opposed to DML->LDI->rollback, this test runs fine since cpimport commits
#-- for LDI, then the subsequent DML would run fine since dmlproc can get the table lock.
