Obligatory sections of printing program:

• declaration of a variable (context), using ABAP-dictionary type;

• implementation of logic for filling the variable (context);

• call a function module 'ZXLWB_CALLFORM', passing the variable (context) and form name as importing-parameters.

Example of a simplest printing program:

REPORT  z_shipping_label.

* declare a context

DATA gs_context   TYPE zcontext_shipping_label .

* fill the context

gs_context-to_name    = 'Dan Tedford' .

gs_context-to_street  = '811 Alworth Avenue' .

gs_context-to_town    = 'Middlefield' .

gs_context-to_state   = 'CA' .

gs_context-to_zip     = '98567' .

* call the form

CALL FUNCTION 'ZXLWB_CALLFORM'

  EXPORTING

    iv_formname    = 'SHIPPING_LABEL'

    iv_context_ref = gs_context

  EXCEPTIONS

    OTHERS         = 2.

          WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4 .

ENDIF .

Result of the printing program execution:

We see a screen of the viewer containing an application toolbar and a container in which is inscribed OLE-object Excel.
