If a parameter required by the application is missing from the indication, the macro takes the error exit,
with a user error of "Data Missing".
If a parameter not expected by the application is present in the indication, or an expected parameter has a
value not in the set of values permitted by the application, the macro takes the error exit, with a user error
of "Unexpected Data Value".
Otherwise the macro takes the "OK" exit.
The macro is shown in figure 21.2/1.

If the confirmation contains a provider error the macro issues a MAP CLOSE request and takes the
provider error exit.

Otherwise, if a parameter required by the application is missing from the confirmation, or a parameter not
expected by the application is present in the confirmation, or an expected parameter has a value not in the
set of values permitted by the application, the macro takes the data error exit.
