How to Enable and Disable column in Table Control.
Hi all,
I want to make certain column of Table control as Enable or Disable on Button action.
Enable means ready for input and Disable means not ready for input.
Please send me sample code.
Thanks in advance.
Hi Vipin,
You have to loop through the table columns to set the properties in the PBO of your screen.
Here is the sample solution.
delcare a workarea for the columns in the table control in your top include.
Table Control .
CONTROLS: TAB1 TYPE TABLEVIEW USING SCREEN '0100'.
DATA: WA_COLS LIKE LINE OF TAB1-COLS.
in your screen
PROCESS BEFORE OUTPUT.
MODULE INTIALISE_100.
*& Module 0100_INTIALISE OUTPUT
MODULE INTIALISE_100 OUTPUT.
LOOP AT TAB1-COLS INTO WA_COLS.
WA_COLS-SCREEN-INPUT = 1.
MODIFY TAB1-COLS FROM WA_COLS TRANSPORTING SCREEN-INPUT.
ENDLOOP.
ENDMODULE. " 0100_INTIALISE OUTPUT
modify the screen-input property as required for the table control columns.
Please provide points if helpfull.....
Thanks,
Karthik

Disable columns in table control based on condition
Hello Gurus,
I am having a table control in my module pool program.Out of 25 columns , I am having 12 columns on months wise like (jan, feb, march....).Now my concern is based on current month I want to enable the column of month rest all months will be in disable mode.So that the user can enter his/her time of work.Could you please tell me any way.I tired to read tc-cols and stored in col with index but its not working I wrote this code for first month without any condition
READ TABLE tC-COLS INTO col INDEX 22.
col-SCREEN-INPUT = 0.
MODIFY tC-COLS FROM col INDEX 22.
but its not working.I wrote this code in PBO as well as i tried in PAI as wellstill my columns is in enable mode.Also when user clicks on button then only the table control required fields should start working like months enable/disable process.for eg. I am having 2 button one is Create and other is Search on both these buttons after click the condition for enable/disable months should work.
Thanks
GauravHi,
In my scenario, I have used months as radio buttons. A month is selected and "enable" button must be clicked so that only the corresponding column of the month turns into an editable mode.
I have attached the output.
The field can be disabled or enabled by using the line type of <table_control_name>-cols.
It contains the screen elements. For disabling / enabling, use active element in screen.
This must be written in PBO event of the corresponding screen containing the table control.

On basis of drop down by key values i want to enable and disable ui elements is wda
How to enable and disable ui elements on basis of drop down by key values as i show in screen shot i have 3 values in drop down by key on basis of those values i need to enable and disable ui elements in webdynpro abap kindly reply back
Hi Sreedhara,
There are many tutorials on SCN for learning Web Dynpro ABAP. If the following steps don't make sense to you, please do a search for some tutorials and read through the tutorial materials. Hopefully the tutorials will help you to become familiar with some of the basics of Web Dynpro ABAP.
Here is how to enable or disable a UI element upon selection from a DropDownByKey.
In your view context, create a context attribute of type wdy_boolean. For now, let's call this attribute IS_ENABLED
In your view layout, bind the enabled property of the UI element to the context attribute IS_ENABLED.
In your view actions, create an action-- let's call it SET_ENABLED-- and bind this action to the DropDownByKey element's onSelect event in the view layout.
In the event handler method for the SET_ENABLED action, use the Code Wizard to read the value of the DropDownByKey selected value, then use the Code Wizard again to set the value of context attribute IS_ENABLED to either true or false.
Now when a value is selected from the DropDownByKey, the SET_ENABLED action will be triggered and the IS_ENABLED context attribute will be set to either true or false. Since your UI element's enabled property is bound to this true or false value via the context binding, the UI element will change to enabled or disabled.
Good luck!
Cheers,

Not null and enable or disable column in tabular form
Hi,
Using apex version 4.1 and working on tabular form.
ACT_COA_SEGMENT_MAS is Master table
and
ACT_SEGMENT_VALUES_MAS is detail table
I have entered 8 rows in master table and PARENT_SEGMENT_ID is column in master table which is null able. If i specified PARENT_SEGMENT_ID with value in master table then in detail table there is column PARENT_ID that should not be null and enable.
How i can enable or disable column when in master table PARENT_SEGMENT_ID column is null then in detail table PARENT_ID column should disable and vice versa.
I have created tabular form on Detail table. before insert into the tabular form Check in master table in first entry if PARENT_SEGMENT_ID is not null in first row of master table then in tabular form PARENT_ID should enable and not null able in corresponding to this first row id's lines in tabular form.
Same should check for second row in master table if PARENT_SEGMENT_ID is not null then entered rows with PARENT_ID into tabular form corresponding to 2nd id in master table should not nullable and column should enable in tabular form.
Thanks & Regards
Vedant
Edited by: Vedant on Jan 9, 2013 9:12 PMVedant,
You need to create you own manual tabular form and not use the wizard.
Using APEX_ITEM api you should be build you own form and you will be able to control how you wan to display the rows. (See Link [Apex Item Help|http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/apex_item.htm#CACEEEJE] )
select case when PRIMARY_TABLE_COLUMN is null then APEX_ITEM.DISPLAY_AND_SAVE(3 , DETAIL_COLUMN ) else APEX_ITEM.TEXT(2,detail_column) end "ALIAS" from detail table
Hope that help.

How to distinguish between enabled and disabled tasks in SSDT-BI 2012
Hi,
I've got SSDT-BI 2012 together with VS2012 installed. Simple questions: What is the difference between enabled and disabled tasks in control flow from the design/color point of view? I do see that the disabled tasks changes to grey (omg are you really kidding
me????) from black. This could be a bad joke or dream however is not.
So I'm kindly asking you to help me solve this problem. How can I change the color difference between these two options (enabled task vs disabled task)? I do not care whether the one will be yellow or pink, simply just need to be recognizable at first
look and not under long and painful examination.
Thanks for your reply. Hopefully it will be useful.
Karol.Hi Karol,
It’s true that it only changes the font color of the task name text to grey after disabling a task in SSDT 2012. In SSDT 2010, the whole task control including icon will turn grey after it is disabled; in BIDS, the background color of the task control will
turn grey after it is disabled. These behaviors are by design. Personally, I agree with you that this behavior in SSDT 2012 is not very readable.

h.davidHi,
If you want to remove the add-ins of Office 2010 programs, you need to remove it from control panel.
For example, if you use Excel, please try to follow the link to delete the add-ins:

Disable some columns in table control?
Hi
How to disable some columns in table control.
For Ex: Table contains 8 columns.
In first row i want to disable first 4 columns.
in second row i want to disable last 4 columns.
In third row i want to disable first 2 and last 2 columns. How can we achieve this?
Cheers,
Venkys.HI
Create three attribute in the node which is bound to the table as data source.
say pro1, pro2, and pro3 of type wdy_boolean.
now bind the enabled property of first four column editors to pro1, last 4 to pro2, and pro3 to first 2 and last 2.
then go to the eventhandler of the dropdown 's on select event and write the code to update the values of these attribute
according to the selected value.
here is the sample code.
DATA lo_nd TYPE REF TO if_wd_context_node.
DATA lo_el TYPE REF TO if_wd_context_element.
DATA lv_VAL LIKE ls_dealer1-name.
lo_nd = wd_context->get_child_node( name = 'DEALER1').
lo_el = lo_nd->get_element( ).
lo_el->get_attribute(
EXPORTING
name = `NAME`
IMPORTING
value = lv_VAL ).
DATA PR1 TYPE WDY_BOOLEAN.
DATA PR2 TYPE WDY_BOOLEAN.
DATA PR3 TYPE WDY_BOOLEAN.
PR1 = ABAP_TRUE.
PR2 = ABAP_TRUE.
PR3 = ABAP_TRUE.
IF LV_VAL EQ 'A'.
PR1 = ABAP_FALSE.
PR2 = ABAP_TRUE.
PR3 = ABAP_TRUE.
ELSEIF LV_VAL EQ 'B'.
PR1 = ABAP_TRUE.
PR2 = ABAP_FALSE.
PR3 = ABAP_TRUE.
ELSEIF LV_VAL EQ 'C'.
PR1 = ABAP_TRUE.
PR2 = ABAP_TRUE.
PR3 = ABAP_FALSE.
ENDIF.
LO_EL->SET_ATTRIBUTE(
NAME = 'PRO1'
VALUE = PR1
LO_EL->SET_ATTRIBUTE(
NAME = 'PRO2'
VALUE = PR2
LO_EL->SET_ATTRIBUTE(
NAME = 'PRO3'
VALUE = PR3

I have also created a button with which user can create a new record from the same tabkle control and t/f back that new value in the itab.
Now, when table control is displayed it WILL have certain records in it. I want those records to be in the INPUT = '0' state and rest of the table control lines should be INPUT = '1'.
I am trying....

"Max points are assured"Hi....
Actually.... our table control.. is by defalut make disable the empty rows... which are not having data...
because... the process of dispaly table control like this...
1.Fetching the records from database into one itab...
2.Capturing the itab lines with following sytax...in the PBO module..
> MODULE <TC>_CHANGE_TC_ATTR OUTPUT.
> DESCRIBE TABLE ITAB LINES <TC>-lines.
> ENDMODULE.
with this you are sizing the table control as for itab size...
3. Filling or Attaching the itab with Table control...
> LOOP AT ITAB
> WITH CONTROL TC
> CURSOR TC-CURRENT_LINE.
> MODULE TC_GET_LINES.
> ENDLOOP.
So in above module we can fill data and can disable and enable rows of certain condition...
So the condition aplleid rows should be disable and remaining enable.. and important thing is empty rows should be defaultly disabled mode...
But.. Here you want to appear empty rows should be in enable mode...
For that in second step.... modify the code like this....
> MODULE <TC>_CHANGE_TC_ATTR OUTPUT.
> DESCRIBE TABLE ITAB LINES <TC>-lines.
> <TC>-lines = <TC>-lines + 4.
> ENDMODULE.
So with this you can get 4 empty and enable lines...
and if u are not having 2nd step in ur coding.. just write it now.. it will solve ur problem...
Pleae get back to me if you want any further clarification...
Thanks,

Reg:How to delete the column in table control also from database table.
Hi Experts,
Once again thank u all for giving the responses.
one more doubt is how to delete the columns of table control and also the record shold delete from ztable.
With Regards,
Saroja.P.Hi,
If you want to delete the rows in the table control and simultaneously delete it from the database table, then you can implement a 'DELETE' functionality specific to your table control. Have a MARK field (you will find that in the screen attributes of the table control -> give a name for the MARK field, you will find an additional MARK column at the beginning of your table control). You can check whatever rows you want to delete from the table control, call the delete module.
"This portion of code inside the LOOP...ENDLOOP.
IF sy-ucomm eq 'F_DELETE'.
gt_itab2-check = mark. " Store the MARK field status into your internal table's correspoding field 'check'
MODIFY gt_itab INDEX tabcontrol-current_line.
ENDIF.
iF sy-ucomm eq 'DELETE1'.
DELETE gt_itab WHERE check eq 'X'. "Your internal table does not have rows that you want to delete
ENDIF.
Now you can modify your database table using the MODIFY statement.
MODIFY ZDB FROM TABLE gt_itab. -

How to add a column in table control
Hi ,
Can any one tell me how to add a column in table control? My requirement is to add two columns ( custom fields ) into table control ( It is a standard program). I have added the column in the table and also in the table control. But when I am running the standard program, The newly added column is not there. But I have added in the perticular screen. Change is not reflected.
Can anyone help me on this please.
Thanks in advance.
Regards,
Lakshmi.Hi,
Ensure the following :
1. After adjusting the database, you`ll have to use the database utility and activate the table.
2. If you have changed the standard screen, in tcode se80 -- right click on the program and click activate all. This activates all objects related to that program.
Now execute the program.
Reward if helpful.
Regards
