ABENOO_OBS_CALL_DIALOG_1 - OO OBS CALL DIALOG 1

No Implicit Field Names When Calling Dialog Modules

To call dialog modules, the names of the fields from or to which data is transferred must be specified explicitly in ABAP Objects.

In ABAP Objects, the following syntax causes an error message:

CALL DIALOG ... EXPORTING f1 ... fn
                IMPORTING f1 ... fn.

Correct syntax:

CALL DIALOG ... EXPORTING f1 FROM f1 ... fn FROM fn
                IMPORTING f1 TO   f1 ... fn TO   fn.

Reason:

The use of implicit names can cause errors. With the implicit method, the system tries to find global data objects in the called program whose names are literally the same as the names specified after FROM or TO. If offset/length specifications or preceding selectors are used in the names, data objects with identical names cannot exist in the called program.
