WRITE_FORM   Locate the document in its SAP Library structure

The system outputs the form element specified in parameter ELEMENT into the currently opened form.

In the parameter WINDOW you can specify the name of a window for the output. Remember that the form element must be defined in this window. The parameter FUNCTION specifies how to merge the text lines to be output with any existing contents in the window. In this case, there are differences between the different window types or areas.


Function call:














Export parameters:


Specify the name of the text element you want to output into the form window specified in the parameter WINDOW. The element must be defined in that form window. If you specify no element, the system uses the default element, if one is defined in the form.

Default value: SPACE


Specify the name of the window into which you want to output the form element specified in the parameter ELEMENT.

Default value: 'MAIN'


The parameter determines how to output the text element into the respective window. The output type depends on the window type and area:

Window type MAIN, area BODY:

'SET' append to previous output

'APPEND' same as SET

'DELETE' no effect

Window type MAIN, areas TOP and BOTTOM;

all other windows:

'SET' delete old window or area contents and

output the element

'APPEND' append the element to the existing elements 'DELETE' delete the specified element from the window

or area


DELETE in the TOP area (headings) takes effect only on the next page. You can no longer delete any heading from the TOP area after outputting text to the BODY area.


Default value: 'SET'


The system interprets this parameter only for output to the main window.

The parameter determines the area of the main window into which you want to output the element.

Possible values:

'TOP' header area

'BODY' main area

'BOTTOM' footer area

Default value: 'BODY'


Import parameters:


If a text is output to the BOTTOM area of the main window (TYPE = 'BOTTOM'), there may be not enough space left on the current output page. The system then internally flags this text for output into the BOTTOM area of the next page. The actual output is pending.

If output is pending, the parameter PENDING_LINES contains 'X', and the print program can react accordingly. For example, an explicit page break at the text end (NEW-PAGE) could implicitly trigger the pending BOTTOM output on the next page.




The parameter ELEMENT contains the name of a form element that the system could not find.

Possible reasons:

  • The element does not exist.

An element refers to a window, and the specified window does not contain the element. If no window is specified, the system searches for the element in the main window.

  • The specified element is not defined in the form.
  • The form version that contains the text element in the specified form window is not active.


The function specified in parameter FUNCTION is unknown.

For this parameter, the following values are allowed:





The type of window area specified in parameter TYPE is invalid.

Depending on the window type, these entries are valid:

  • BODY: for all windows
  • TOP: only for the main window
  • BOTTOM: only for the main window


The current form function could not be executed, since the form output was no yet initialized using OPEN_FORM.


No form was opened yet.

Possible reasons:

  • The form processing was started using OPEN_FORM without specifying a form name, but no form was opened yet using START_FORM.
  • The last used form was closed using END_FORM, but no new form was opened using START_FORM.
  • The last filled page of the current form has no subsequent page. In this case, the system automatically terminates form printing after this page. You need no explicit END_FORM call.
  • In the current form, no page contains a main window, but a text element shall be output in the main window.


The form window specified in parameter WINDOW does not exist in the current form.

Possible reasons:

  • A wrong window name was specified.
  • The form version, which contains the specified window, is not active.
