How to make the current value default programmatically

How to make the current value default programmatically

Open a VI reference to the desired VI and use invoke mode with method: "Make current values default".
The VI cannot be running, so you need to set it from a different VI. (It also means, it cannot set itself.)

Hi there! Just want to know how to make a category highlighted after user click on it, so he will able to track on which category he is currently on?
I've already created 3 categories (links) through creating library elements, I already have the hover effect I made through CSS external stylesheet, everything works, but the category is not highlighted when I browse within it.
Here is my HTML code of these 3 links:
<td bgcolor="#663300">
<div align="right" class="link"><a href="index.html">Home</a>     <a href="Accessories.html">Accessories</a>    <a href="Contact Us.html">Contact Us</a>    </div>
</td>
And here is my CSS code for these links:
.link, .link a:link, .link a:visited, .link a:active {
    font-family: "Times New Roman", Times, serif;
    font-size: 18px;
    font-weight: normal;
    color: #FFFF33;
    text-decoration: none;
    padding: 5px;
    #home: color:#00FFFF;
.link a:hover {
    font-family: "Times New Roman", Times, serif;
    font-size: 18px;
    font-weight: normal;
    color:#FF0000;

Creation of a Personalised LOV in a seeded OAF page

Hi,
I am trying to create a LOV item (personalised/CO extension) in a seeded OAF page.
When I am trying to do from Create Item option of personalised page then I cannot find the option for creating the LOV mappings.

Please suggest.

How to make a SELECT LIST READONLY

Hi,
I have a form to update the existing values in a table. Primary column is based on a Select List.
So when user goto update screen they SHOULD NOT BE ABLE TO CHANGE the primary filed(means the value display in the Select List).
SO to make this one I have make that select list read only. But not like other items even when we make select list read only it still allow user to change the value. So basically read only property not working for select text.
There are many post in this regading same issue. Some of them recomended to make it disabled. But when we make a item disabled then when user POST that form, Apex not POST any disabled item values. Basically disabled items values not passing next form. So making item dissable also not a solution.
I have read almost 20 post in here regarrding this and didnt get any solution for this. So please let me know if anyone knows how to make a select list read only (which is working same as read only text boxes, means that value pass when user POST the form).
Thanks in advance...

You define a function(this is based aorund jQuery selectors) in the page header like
<script>
var makereadonly = function(selector, makeReadonly) {
      $(selector).filter("select").each(function(i){
          var select = $(this);
          //remove any existing readonly handler
          if(this.readonlyFn) select.unbind("change", this.readonlyFn);
          if(this.readonlyIndex) this.readonlyIndex = null;
          if(makeReadonly) {
              this.readonlyIndex = this.selectedIndex;
              $(this).css('background-color','#CDCDCD'); //Adds a background colour to readonly item
              this.readonlyFn = function(){
                  this.selectedIndex = this.readonlyIndex;
              select.bind("change", this.readonlyFn);
      //For input items
      $(selector).filter("input,textarea").attr('readOnly','readOnly');
      $(selector).filter("input,textarea").css('background-color','#CDCDCD');
</script>and apply it using a jQuery selector (call it in the "execute on page load" or any other JS code)
makereadonly('#ITEMNAME1,#ITEMNAME2,#ITEMNAME3',true);Not that all of these methods(that act at the client side) will only prevent the user from modifying it 'normally', they could manipulate these readonly items using Javascript(or using firebug or any tool like that). So its better to make sure that your don't use the item value(from the page) for processing.

How would I make a program restart at the click of the mouse or a key on the keyboard?

How to make a tabular form readonly based on an item value

Hi everyone,
I am getting there, but I need to make a tabular form read-only based on an item value.
I've copied this from somewhere (thanks) and changed it for my needs and it works great to set the second column of my form
to read only.
    var els = jQuery('#Entry_Form input[name="f02"]');
    /*var r = confirm("els is " + els);*/
    els = els.filter(function(index){
      return jQuery(this).val() != "";
    });Just need to set the jQuery selector to jQuery("td[headers='PRODUCT_NAME']"), cos that's my column name.
also need to give a static id of Entry Form to the form.
I'll try to understand what this code means exactly one of these days, but now I need to make
the whole tabular form read only based on a text item, :P5_CONTROL.
Grateful for any help on this, in the above format if possible. Greek to me but compact and it works.
Regards.

Hi,
actually, there is no code, just one dynamic action. You may have to change the event which triggers it.
Event: Change
Selection Type:     Items(s)
Item(s): P1_ED
Condition: equal to
Value: D
True Action 1
Action: Disable
Fire On Page Load: yes
Selection Type: jQuery Selector
jQuery Selector: input[id^="f"]
True Action 2
Action: Disable
Fire On Page Load: yes
Selection Type: jQuery Selector
jQuery Selector: input[id="check-all-rows"]
False Action 1
Action: Enable
Fire On Page Load: yes
Selection Type: jQuery Selector
jQuery Selector: input[id^="f"]
False Action 2
Action: Enable
Fire On Page Load: yes
Selection Type: jQuery Selector
jQuery Selector: input[id="check-all-rows"]

How to make a component as readonly dynamically....

Hi,
I have a requirement and working on it since long time... I want to make a component readonly at runtime...
I have to take a value(true/false) from message bundle and based on that value, I have to create a component as readonly or not...
How to do this....
I tried to do like below...
<h:inputText style="width:170px;" value="#{bean.firstName}" readonly="#{msg.readOnlyFirstName}"></h:inputText>
but it is giving exception like this...
org.apache.jasper.JasperException: Could not get property readonly of component
Please help me on this...
thanks in advance..

Hi,
I think i should give answer to your question in two folds,
#1) Dont use the properties files for such opeation(enable and diaplbe of component), and if you wnat to use this then you need to do it via backing bean. What you have to do is, you can declare a property in backing bean of that page whcih will tell rendered about the enabling/disabling the particular component. To set the property delclared in backing bean read the property file and then set it to true or false based on your need.
#2) Use backing bean directly by omitting the property file from picture.
By taking a look at your exception it seems that the something is wrong with readonly attribute, can u post complete exception.

How to make a default value by using dynamic actions

Hi,
       I want to default a field nationality in infotype 0002 as a great britan, using dynamic actions but unable to go ahead. Any help regarding this really appreciate.
Regards
Niranjan

Hi,
I need some guidance around creating dynamic action with default value, Please guide me through.
I am aware I can set default values for new infotype, but I need to set default value for same infotype, let me explain the scenario.
Currently employee is on one pension scheme which is called NE1 and now we are moving this employee to CRESP Pension Scheme.
When employee is in NE1, his IT0071 has got a opt in field with a flag on, when the same employee is moved from NE1 pension scheme to CRESP Pension scheme, his new IT0071 record should have the same opt in field with a flag on, I want it to set this flag automatically using dynamic action. I dont want to update this field manually, while moving from NE1 to CRESP.
Currently the below dynamic action is coded when employees are being moved form NE1 to CRESP, but now they will have a opt in flag which should appear automatically, What needs to be done to make this happen?
Please let me know if I set default value for the Opt in field for the same infotype.
. When employees are being moved from NE1 to CRESP pension scheme we currently use a dynamic action as show below:
0071                      04      10      I        INS,0069
0071                      04      20      W       P0069-BEGDA=P0071-BEGDA
0071                      04      30      W       P0069-ENDDA=P0071-ENDDA
0071                      06      1        F        DYNACT_PAE031(ZHRPROG016)
Also if it is not possible via dynamic action could you please explain how to create it using user exit, I am not an ABAPer.
Your help is very much appreciated.
Kind Regards,

How to make use of values in calling program in a badi

Hi
I have a badi implementation. i need to make use of some values in the program in the BADI. how do i access values in the program in the BADI.
Regards,
Chaitanya

You can try this:
E.g (replace the table and program names with the one you need).:
CONSTANTS: c_resbd(15) TYPE c VALUE '(SAPLCOIH)resbd'.
FIELD-SYMBOLS: <fs_resbd> TYPE resbd.
ASSIGN (c_resbd) TO <fs_resbd>.
If this doesn't work try exporting the variables you need to memory from a field/user exit.

How to make the same value be placed in many variables.

Hi all!
I need help to make the values broght from ekpo-peinh: 1 2 3 4 5 etc... get placed into many fields of internal table, for example:
data: begin of it_size occurs 0.
        t90 like ekpo-peinh,
        t10 like ekpo-peinh,
        t11 like ekpo-peinh,
        t12.....
      end of it_size.
And I need to make that all the values from ekpo-peinh be placed in order in it_size-t90 = 1, it_size-t10 = 2, it_size-t11 = 3, it_size-t12 = 4 and so on.
So please if anyone can help me 'cause I don't know how to do that, I'll really appreciate it.
Thanks for your time.

Hi Guillermo.
I'm not sure i understand completely, but here's part of a solution:
data: l_comp type i,
      l_type.
field-symbols: <f> type any.
describe field it_size type l_type components l_comp.
do l_comp times.
assign component l_comp of structure it_size to <f>.
if sy-subrc ne 0.
    exit.
endif.
move (value from EKPO) to <f>.
enddo.
This will populate, in order, your IT_SIZE structure with a value (EKPO-PEINH). I'm not sure how this value is managed, but this should give you an idea.
