disable rows in table control

Posted on Apr 08, 2008 at 03:18 PM 517 Views

Hi ,

I want to disable the rows in table control . Here is the code I wrote to fill the table control .

Please advise .

LOOP WITH CONTROL table_TC.

MODULE FILL_CONTROL.

ENDLOOP.

MODULE FILL_CONTROL.

SELECT * INTO TABLE itab FROM ztable

WHERE WERKS = S_ztable_TMP-WERKS

AND NORMT = S_ztable__TMP-NORMT.

READ TABLE itabe

INDEX table_TC-CURRENT_LINE.

IF SY-SUBRC = 0.

MOVE-CORRESPONDING itab TO table.

ELSE.

EXIT FROM STEP-LOOP.

ENDIF.

For disabling the rows I tried this but get an error message

""LOOP" cannot be assigned to any field."

LOOP AT itab WITH CONTROL table_TC.

MODULE CLEAR_OUTPUT.

ENDLOOP.

Thanks !!

Teresa

in your PBO routine

*&spwizard: module TC_TEST1_change_tc_attr.
*&spwizard: module TC_TEST1_change_col_attr.
  loop at   g_TC_TEST1_itab
       into g_TC_TEST1_wa
       with control TC_TEST1
       cursor TC_TEST1-current_line.
    module TC_TEST1_change_field_attr   "<== Here change your screen attributes.
    module TC_TEST1_move.
  endloop.

Teresa,

I wrote a very simple program to test this. I have a single column table for just a salesperson number.

I made a simple module that while it was going thru the attr changing, I simply flipped the intesified flag on and off on alternating rows

of the table. This code worked on v4.6c.

I hope this can help you. The only thing I can't show you is the actual screen which only has the Table Control (which started the wizard by adding it on the screen) on it.. and I had the Wizard add the INSERT and DELETE buttons so I could prove the program.

The Flow Logic for the screen


PROCESS BEFORE OUTPUT.

  MODULE init_table.

*&spwizard: pbo flow logic for tablecontrol 'TC_TEST1'
  MODULE tc_test1_change_tc_attr.
*&spwizard: module TC_TEST1_change_col_attr.
  LOOP AT   it_wk
       INTO wk_rec
       WITH CONTROL tc_test1
       CURSOR tc_test1-current_line.

    MODULE tc_test1_get_lines.

    MODULE tc_test1_change_field_attr.   "<== here is the module call for the attribute setting
  ENDLOOP.


  MODULE status_0100.
*
PROCESS AFTER INPUT.
*&spwizard: pai flow logic for tablecontrol 'TC_TEST1'
  LOOP AT it_wk.
    CHAIN.
      FIELD wk_rec-spnum.

      MODULE tc_test1_modify ON CHAIN-REQUEST.
    ENDCHAIN.
    FIELD wk_rec-sel
      MODULE tc_test1_mark ON REQUEST.
  ENDLOOP.

  MODULE tc_test1_user_command.
