Hi,

main window is used to display line items.

variable window is used to display address such type of stuff.

constant window is used to display total etc.

Hi,

WINDOW TYPES

When defining a layout set window, you must select a window type for the window. You can choose between three types:

• Constant windows (CONST)

• Variable windows (VAR)

• Main windows (MAIN)

MAIN WINDOW

Each layout set must have one window of type MAIN. Such a window is called the main window of the layout set. For SAPscript layout sets, the main window has a central meaning:

• It controls the page break.

• It contains the text body that may cover several pages.

• It allows to fix text elements at the upper and lower margins of the allocated page window (for example, for column headings).

As soon as a window of type MAIN is full, SAPscript automatically triggers a page break and continues to output the remaining text in the main window of the subsequent page. Page windows of type MAIN have the same width throughout the layout set. The SAPscript composer thus avoids reformatting of the text after each page break.

If a page does not have a main window, the system implicitly processes all other windows of the page and continues with the subsequent page. This page must not call itself as subsequent page (recursive call), since this would produce an endless loop. In such a case, SAPscript terminates the output after three subsequent pages.

Window MAIN controls the actual layout set flow. When the MAIN window is full, a new layout set page is started.

VARIABLE WINDOW

The contents of variable windows is processed again for each page, on which the window appears. The system outputs only as much text as fits into the window. Text exceeding the window size is truncated; the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different layout set pages.

As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike. The only difference is that constant windows have the same size throughout the layout set.

CONSTANT WINDOW

A window of type CONST has the same contents and size on all layout set pages, on which a corresponding page window is defined. This allows the processing of the window contents to be optimized internally.

Page windows whose allocated window is of type CONST must have the same size throughout the layout set. If a window of type CONST is full, all remaining text the application program wants to output in this window, is lost. Constant windows do not trigger a page break. In other words: all text exceeding the window size is simply truncated.

Hi,

WINDOW TYPES

When defining a layout set window, you must select a window type for the window. You can choose between three types:

u2022 Constant windows (CONST)

u2022 Variable windows (VAR)

u2022 Main windows (MAIN)

MAIN - A layout set can have only one MAIN window which is created by default. This window can flow over multiple pages.

CONSTANT - A window of type CONST has the same contents and size on all layout set pages, on which a corresponding page window is defined. A layout set can have any number of constant windows. A constant window can be used once per page

VARIABLE - The contents of variable windows is processed again for each page, on which the window appears. The system outputs only as much text as fits into the window. Text exceeding the window size is truncated; the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different layout set pages.

NB : As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike. The only difference is that constant windows have the same size throughout the layout set.

Hello naresh,

1) In Scripts, the window can be of type VAR or CONST except for the MAIN.

2) The content of variable window is regenerated on every page.

3) The content of a constant window is generated once at the beginning and later printed on every page.

4) But in the present versions, SAP system does not distinguish between these two types

MAIN - Main Window

The main window is a continous window which can extend over several pages. If the text in the main window fills up a page, a new page is created.

Only one main window can be defined in the SAP Script whereas upto 100 instances of main window can be created in a page.
