READ_FORM_DATA

Read FAB App Instance Data.

This method can be used to obtain the data of a FAB Instance.

The method returns ‘TYPE REF TO DATA’ via parameter ER_DATA. This can be assigned to a field symbol and move into a corresponding structure that matches the T_DATA (GS_DATA) declaration in an implementation class.

Example:

          DATA: lo_assist TYPE REF TO /iqx/cl_forms_assist,
                lo_data   TYPE REF TO data.
          FIELD-SYMBOLS: <fs_fdata> TYPE any.

          CREATE OBJECT lo_assist.
          CALL METHOD lo_assist->read_form_data
            EXPORTING
              iv_form_name     = lv_form_name
              iv_instance      = lv_instance
            IMPORTING
              er_data          = lo_data
            EXCEPTIONS
              no_instance_data = 1
              OTHERS           = 2.

          ASSIGN lo_data->* TO <fs_fdata>.
          DATA: ls_data TYPE ZCL_YOUR_IMP_CLASS=>T_DATA.  "if public or friend
          MOVE-CORRESPONDING <fs_fdata> to ls_data.
