Main components in Smart Form in SAP ABAP.

 What are the main components in Smart Form?

Main components in Smart Form in SAP ABAP.

Ans: The main components are, 1. Global Settings       2. Pages & Windows

           1. Global Settings: It is used to maintain the global settings, definitions which can be applied          across the mart forms. It is collection of Form Attributes, Form Interface & Global Definition

                      I.        Form Attributes: These are used to maintain the smart form attributes & output such are page format, style name etc. The default style for smart form is ‘SYSTEM’.                                                

                    II.        Form Interface: These are used to declare the variables, work areas & internal tables 

        which are needed to transfer the data from print program to layout. It is the system                       generated function module with all the parameters except changing parameters.

III. Global Definitions: It is used to maintain the global definitions which can be used across        the different Global definitions.

                    a) Global Data: It is used to maintain the global data definitions such are variables, work                                           areas, Internal Tables etc.

     b) Types: It is used to define the types which can be referred to declare internal tables &                    work areas.

     c) Field Symbols: It is used to define the field symbols.

     d) Initialization: It is processed before the smart form pages & windows are processed. It                           is used to extract all the required data from the database table &                                             process the extracted data. Import & Export parameters must be                                        specified before they are used.

     e) Form routines: It is used to define the subroutines which can be called across the                                                           smart form. It is used to define the currency/quantity fields as like the                                             DDIC tables/structures. 

       f) Currency/Quantity Field: It is used to define the Currency/Quantity Fields as like the                                                                 DDIC tables/structures.

            2. Pages & Windows: It is used to design the different page formats & windows. Following                                               are the different nodes in smart forms.

a)    Windows: They are positioned on the pages. Following are different type of windows.

Ø  Main Window: It is used to display the continuous text on the pages. This window is the  default widow. Without main window also we can design Smart forms.

Ø  Secondary window: It is used to print the different contents on each page (similar to variable window in SAP Scripts).

Ø  Copies window: It is used to the print the same document with multiple

                           copies with different headings.

Ø  Final window: This is used to print the total amount after all the lines or line items are printed.

b)    Graphics: It is used to create a graphic node (window) to display the graphics/logos.

c)    Address: It is used to define the address node/window to display/print the organization address/personal address/work place add/ress.

Ø  The address can be determined dynamically also using an option Determine Dynamically.

d)    Text: It is used to display/print the contents of the different symbols/fields.

e)    Table: A table is used to print the multiple entries/dynamic data of an internal table. The Table node can be used as template to display static record by un-checking the checkbox internal table. Line types can be created under Table node.

f)     Template: A Template is used to display the static data (single record). This node does not have the separate header, main area & footer whereas, the table node contains the different sessions such are header, main area & footer. The template node can be used as table by defining it under loop node to display the dynamic data as like the table node.

g)    Flow logic: The flow logic nodes are used to control the nodes & define the program lines in smart forms. Following are the different flow logic nodes.

                                        I.        Loop:  It is used to process the corresponding nodes based on the number of entries of an internal table.

                                      II.        Program lines: It is used to write ABAP source code. Input & Output parameters must be filled with the data variables before they are used.

                                     III.        Alternative: It is used to control the corresponding nodes based on the specified condition. It is used to process the alternative either True/False process blocks based on the SET conditions.

                                    IV.        Command: This node is used to go to a new page based on the specified conditions. This is used to break the page based on the condition.
