MODULE
Other versions: 7.31 | 7.40 | 7.54
Syntax
MODULE mod {OUTPUT|[INPUT]}.
...
ENDMODULE.
Addition
Effect
The MODULE statement defines a mod
dialog module. The
naming conventions apply to the name mod.
The functions of a mod dialog module are implemented between the MODULE ad ENDMODULE statements.
A dialog module is called using the MODULE statement with the same name of the
dynpro flow logic of any ABAP program
dynpro.
Addition
... OUTPUT|[INPUT]
Effect
The OUTPUT and INPUT additions determine whether the dialog module can be called for the
PBO event or for the
PAI event. The INPUT
addition is the default and can therefore also be omitted, although this is not recommended for the
readability of the program. Two dialog modules with the same name can be defined in a program, if one
of them has the OUTPUT addition and the other has the INPUT addition, which is not recommended again for reasons of readability.
Note
For data encapsulation reasons, we recommend that you implement little functionality in dialog modules, and that you call procedures instead.
