Dynamically hide a screen field based on view cluster variant.

Former Member — Thu, 22 Aug 2013 07:20:14 GMT

Hello All,

I have a view cluster and two view cluster variant. In the screen I have a table with few columns. For one of the view cluster variants, I want to hide one of the columns of the table. Since both the view cluster variant is linked to the same view cluster that is to the same screen, I am dynamically suppressing the column w.r.t the view cluster variant.

This is the piece of code I have written:

loop at screen.

if screen-name = 'FSH_SOFN_V-DOCTYPE' and fsh_sofn_v-soobj = 'ST'.

screen-input = '0'.

screen-output = '0'.

screen-invisible = '1'.

screen-active ='0'.

modify screen.

endif.

ENDLOOP.

This piece of code hides the values of this particular screen field, but it is still shown in the UI. I want to completely remove it from the UI whenever I execute the view variant.

I feel Since I have not written any code to remove it from the table control of the screen , it is still shown in the Table at UI.

The screens developed here are done from table maintenace generator , so it's all automated. Not getting how to change the table control values.

Could you please provide your inputs.??

I have attached a screenshot where I have highlighted the column to be removed.

Hi Arun,

I am trying to implement the above solution. I am facing some issues.

I have used a table maintenance generator. So Depending on the Fields I have choosed, screen is automatically generated with table control : TCTRL_FSH_SOFN_V.

Now, I have to declare a work area to store the values of the above type.

How do i do it??

The highlighted portion gives an syntax error as the table control is not defined.

data: wa_FSH_SOFN_V_cols type LINE OF TCTRL_FSH_SOFN_V-COLS.

loop at TCTRL_FSH_SOFN_V-COLS to wa_FSH_SOFN_V_cols."into .

if sytabix = 4.

wa_FSH_SOFN_V_cols-INVISIBLE = 1.

MODify TCTRL_FSH_SOFN_V-COLS from wa_FSH_SOFN_V_cols.

endif.

endloop.

Rohit,

Declare using like instead of type.

data: wa_FSH_SOFN_V_cols LIKE LINE OF TCTRL_FSH_SOFN_V-COLS.
