Dynamic header in table control doesn't work

[former_member230234]

Hi! I'm trying to assign dynamic headers to columns in a table control of a dynpro.

I create a I/O field instead a the text field:

I create a global variable TEXT_AZT and I try to assign te text from a table.

LOOP AT SCREEN. 
  IF screen-name = 'TEXT_AZT'. 
    CLEAR ls_wcm_dycon. 
    READ TABLE lt_wcm_dycon INTO ls_wcm_dycon 
               WITH KEY dynpro_obj = 'TEXT-AZT' 
               BINARY SEARCH. 
    IF ls_wcm_dycon-con_mask = 'X'. 
      READ TABLE lt_wcm_dycon_t INTO ls_wcm_dycon_t 
                 WITH KEY dynpro_obj = 'TEXT-AZT' 
                 BINARY SEARCH.
      TEXT_AZT = ls_wcm_dycon_t-mascara. 
      MODIFY SCREEN. 
    ENDIF. 
  ENDIF. 
ENDLOOP.

But It doesn't work and the header appears with blank. Anybody knows what am I doing wrong? Thanks.

Hi people! I find the solution just now. In the PBO the table control is fill in previously of the init module. I can change all fields in any point of the PBO but in order to change the view of a table control we have to "paint it" before load any data to the table control.

Thank you if you try to help me.
