Correct the user program so that
the relevant instruction is executed
after the DB Map Variable is
created by a DB_CreateMapping
instruction.
Write the user program so that the
relevant instruction is executed
after the DB Map Variable is
created by a DB_CreateMapping
instruction.
A variable that is not registered
as a DB Map Variable was
specified in MapVar.
Check the input parameters of the
relevant instruction and correct the
user program.
In the input parameters of the
