Input Help in Dialog Modules
To define input helps in dialog modules, dialog modules can be called at POV time:
PROCESS ON VALUE-REQUEST.
FIELD field MODULE mod.
PROCESS ON VALUE-REQUEST,
MODULE statement can only be used in combination with the
statement. When F4 is selected, the dialog module
FIELD statement whose field
field has the
cursor. If multiple
FIELD statements are specified for the same field
field, only the first statement is executed. The dialog module
does not provide the content of the dynpro field
field, since this content
is not transported by the
FIELD statement at
PROCESS ON HELP-REQUEST time. If the recommended
search helps and search help exits do not meet requirements, proposal lists for the input help can be programmed in this dialog module.
Function modules are available here that support both search helps and all other types of input help, and which also transport data between the dynpro and the ABAP program. These function modules are prefixed with F4IF_. The most important are:
The additional function modules DYNP_VALUES_READ and DYNP_VALUES_UPDATE read and return dynpro fields at POV time. For further information, refer to the relevant function module documentation.
