ABAP_DYNPRO - Field Help There are three ways of displaying field help for screen elements on dynpros: ITOC
Displaying the Documentation of the Data Element If a screen element in the Screen Painter was defined by copying a field from the ABAP Dictionary, the documentation of the associated data element is displayed automatically when the F1 help is selected for this field, unless this step is overridden in the dynpro flow logic.
Displaying the Supplementary Documentation of the Data Element The documentation of some data elements has supplementary documentation. The supplementary documentation for a dynpro field is created in the Screen Painter and not in the ABAP Dictionary in the ABAP Workbench. Here, the supplementary documentation is defined for the data element using a number. Supplementary documentation of this type is specific to a program and to a dynpro. Any supplementary documentation with the same number defined in the ABAP Dictionary is overridden by any dynpro-specific supplementary documentation. Supplementary documentation defined in ABAP Dictionary can still be linked with a dynpro field in table THLPF . This requires a new line in table THLPF containing the program name, dynpro number, field name, and the number of the supplementary documentation. To be able to display the supplementary documentation, the dynpro flow logic must respond to the POH event as follows: PROCESS ON HELP-REQUEST. ... FIELD field [MODULE mod] WITH hlp. ... Only FIELD statements are allowed after PROCESS ON HELP-REQUEST. If the flow logic of a dynpro does not contain the event keyword PROCESS ON HELP-REQUEST , F1 displays either the data element documentation of the field on which the cursor is positioned or no help documentation is displayed. In other cases, the following FIELD statement is executed on whose field field the cursor is positioned. If dynpro-specific supplementary documentation exists for the field field, this is displayed by specifying its number hlp. A variable hlp can be filled before the help is displayed, for example, by calling the dialog module mod. At the event POH, the FIELD statement does not, however, transport the content of the dynpro field field to the ABAP program.
Calling Help Texts in Dialog Modules Any help text can be displayed by calling dialog modules at POH: PROCESS ON HELP-REQUEST. ... FIELD field MODULE mod. ... After PROCESS ON HELP-REQUEST, the MODULE statement can only be used in combination with the FIELD statement. When F1 is selected, the dialog module mod of the FIELD statement on whose field field the cursor is positioned. If multiple FIELD statements are specified for the same field field, only the first statement is executed. The dialog module mod 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. The dialog module mod is defined like a regular PAI module in the ABAP program. The processing logic of the module must ensure that adequate help is displayed for the selected field. Function modules such as HELP_OBJECT_SHOW_FOR_FIELD or HELP_OBJECT_SHOW can be used to do this.
