Table control does not display all rows

Question

I have a problem where not all of the rows of my table control are being displayed in ABAP 740 SP13.

For example, I have a table with these two rows:

This is the state of the table where this code is executed:

CALL SCREEN 0300 STARTING AT 10 5
                 ENDING AT 85 16.

This goes immediately into my Process Before Output code:

*----------------------------------------------------------------------*
*                        PROCESS BEFORE OUTPUT                         *
*----------------------------------------------------------------------*
PROCESS BEFORE OUTPUT.
  MODULE status_0300.
  LOOP AT lt_transfer_confirm_tc
         INTO ls_transfer_confirm_tc
         WITH CONTROL tc_transfer_confirm
         CURSOR tc_transfer_confirm-current_line.
    MODULE tc_transfer_confirm_get_lines.
  ENDLOOP.

where status_0300 is:

MODULE status_0300 OUTPUT.
  SET PF-STATUS 'STATUS_0300'.
  " Confirm Material Number Count
  SET TITLEBAR 'T05'.
ENDMODULE.

and is tc_transfer_confirm_get_lines:

MODULE tc_transfer_confirm_get_lines OUTPUT.
  g_tc_transfer_confirm_lines = sy-loopc.
ENDMODULE.

At the end of the first iteration of the loop in my PBO, the ls_transfer_confirm_tc value matches with the first row of the lt_transfer_confirm_tc table, tc_transfer_confirm-current_line is 1, and g_tc_transfer_confirm_lines (in tc_transfer_confirm_get_lines) is set to 10.

The second iteration of the loop never processes. The cursor hops from ENDLOOP (from the first iteration) to the line saying CURSOR tc_transfer_confirm-current_line. (as it is the end of the LOOP statement), and finally to ENDLOOP without stopping on the MODULE tc_transfer_confirm_get_lines line. At the end of this loop, ls_transfer_confirm_tc is initial, tc_transfer_confirm-current_line is still 1, and g_tc_transfer_confirm_lines is still 10. All the while, the lt_transfer_confirm_tc table still has two rows in it as shown in the image at the top of this question.

At this point, the screen is displayed as follows:

I'm not sure why this loop doesn't process the second row of my table, and therefore doesn't display it on the screen.

Thanks.

The problem was that I was never setting the value of tc_transfer_confirm-lines, so that the value was always 1.

The following code runs successfully:

*----------------------------------------------------------------------*
*                        PROCESS BEFORE OUTPUT                         *
*----------------------------------------------------------------------*
PROCESS BEFORE OUTPUT.
  MODULE status_0300.
  MODULE tc_trnsfr_cnfrm_change_tc_attr.
  LOOP AT lt_transfer_confirm_tc
         INTO ls_transfer_confirm_tc
         WITH CONTROL tc_transfer_confirm
         CURSOR tc_transfer_confirm-current_line.
    MODULE tc_transfer_confirm_get_lines.
  ENDLOOP.

With the new module tc_trnsfr_cnfrm_change_tc_attr:

*&SPWIZARD: OUTPUT MODULE FOR TC 'TC_TRANSFER_CONFIRM'. DO NOT CHANGE THIS LINE!
*&SPWIZARD: UPDATE LINES FOR EQUIVALENT SCROLLBAR
MODULE tc_trnsfr_cnfrm_change_tc_attr OUTPUT.
  DESCRIBE TABLE lt_transfer_confirm_tc LINES tc_transfer_confirm-lines.
ENDMODULE.
