Hi,

Dynamic documents in ABAP Objects are HTML documents that are generated during runtime using ABAP code.

Dynamic documents enable developers to give totally a new look and feel to ABAP screens and report outputs (provided screens are used in the report output). Many features that are not possible in the traditional ABAP programming are available in dynamic documents. Why we are saying a new look and feel is it uses SAP HTML Viewer internally to bring HTML web page kind of look and feel to screens.

Dynamic documents may contain Forms and Tables, which intern can contain elements like input fields, push buttons, dropdown lists, texts, icons and pictures in different sizes. Of course some of these features are also available in ALV reports with limited usage, but not like in dynamic documents.

Features

The below mentioned are some of the features of dynamic documents.

Large font sizes and more colour options than traditional ABAP/4 (There are some limitations also)

ICONS and pictures in different sizes

Texts

Links

Pushbuttons

Input fields

Dropdown list boxes

Tables with row span and with column span

Tables with frames and without frames

Tables with buttons, icons, pictures, input elements and texts in it

Steps for using dynamic documents in ABAP program:

For using dynamic documents, all that we need is a screen and a custom control in that.

The following steps need to be done in the program in order to display a dynamic document in a screen.

Create a screen and a custom control in that using Screen Painter (This step is not required if we already have a screen and custom control in the program)

Define an object reference to the class CL_DD_DOCUMENT and instantiate it.

For example:

DATA: OBJ_DD TYPE REF TO CL_DD_DOCUMENT.

CREATE OBJECT OBJ_DD.

Dynamic document is ready now for including elements in that. The below are few methods, which we can use for adding elements to the dynamic document. Method Description

NEW_LINE To generate a line break

UNDERLINE To draw a horizontal line across the full width of the document

ADD_GAP To place a gap in a line

ADD_TEXT To add a text

ADD_PICTURE To add a picture

ADD_ICON To add a SAP icon

ADD_TABLE To add a table

ADD_FORM To add a form area

For example:

DATA: OBJ_TABLE TYPE REF TO CL_DD_TABLE_ELEMENT.

CALL METHOD OBJ_DD->ADD_TABLE

EXPORTING

NO_OF_COLUMNS = 2

WIDTH = u2018100%u2019

IMPORTING

TABLE = OBJ_TABLE.

Once all the elements are included, all these elements need to be merged into a single dynamic document. This can be done using method MERGE_DOCUMENT.

For example: CALL METHOD OBJ_DD->MERGE_DOCUMENT.

Dynamic document is now ready for display/print/export.

Method DISPLAY_DOCUMENT can be used to display document in the screen. Here it is possible to display dynamic document in an existing container or in the existing document also.

Method PRINT_DOCUMENT can be used to print the dynamic document. Here system enables local printing.

Method EXPORT_DOCUMENT can be used to export the document as a HTML file into PC.

In case of the dynamic document need to be refreshed based on the user action, one should first call the method INITIALIZE_DOCUMENT to clear the dynamic document contents. This method does not clear the dynamic document object reference. So it is possible to include another set of elements in the same dynamic document.

After displaying the document, any user action can be handled in the event RESOURCES_CHANGED of the class CL_GUI_RESOURCES. For example refreshing the document contents, displaying new contents on the same document etcu2026

Event RESOURCES_CHANGED can be triggered explicitly using the method ON_RESOURCES_CHANGED of the class CL_GUI_RESOURCES.

For showing a dynamic document in a report, a screen with custom control in it must be called from the program.

Example programs:

SAP provided a complete set of example programs (Package: SDYNAMICDOCUMENTS), which explain all the features mentioned in this weblog.

Program Description

DD_ADD_FORM_BUTTON Buttons on Forms

DD_ADD_FORM_INPPUT Interactive Elements: Forms with buttons

DD_ADD_LINK Interactive Elements: Links

DD_ADD_PICTURE SAP icons and pictures stored in BDS(transaction OAOR)

ADD_PICTURE To add a picture

DD_ADD_TABLE Tables

DD_ADD_TEXT Text input

DD_SPLIT_DOCUMENT Distribution of areas on dynamic documents

DD_STYLE_TABLE Style types & list colours
