BAPI &1: Function module for parameter &2 has not been named

What causes this issue?

In the BAPI parameter the "name in function module" is not the same as
the actual name of the parameter in the function module.
For external applications ((Visual Basic, Java, C++ etc.) to be able to
access the SAP System the names have to be the same. The name in the
BOR of the function module parameter belonging to the method parameter
and the name of the actual parameter of the function module must be
identical.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the name of the function module parameter in the BOR or change
the "name in funtion module" for the BOR parameter.
