Dynamic actions

Hi Gurus,
I have coded a perform in a report for a dynamic action to be performed for while updating IT0416.
Could you please tell me that if I am making an entry in the table T588Z will this be accomplished ? Or if not what else I have to do.
Please give a detail reply or if you have something to share in this regard.
Regards,
Binay.

Hi,
I think instead of updating the Database Table directly you must try and use the step provided in IMG(T Code SPRO) to create a dynamic action.
The path in IMG to be followed is
Personnel Management->Personnel Administration->Customizing Procedure-> Dynamic Actions
Make use of the Documentation provided there for better clarity of steps to be followed.
Reward if helpful.

Issue in execution of Dynamic action on change event

Hi,
Greetings.
I have scenario, where I have one select list (P_CATEGORY) and one shuttle control (P_ROOMS) on page.
The values of the shuttle list is being populated based on the selected value in select list.
The left pane of shuttle control's value based on LOV and source of the shuttle item is a plsql function, which returning colon separated value list.
So that returned values shown in the right pane of shuttle.
The LOV values are getting being populated using cascading LOV i.e based on the of Select List item. But the Shuttle source values not getting auto refresh and for achieving that I've created a dynamic true action on change event of Select list.
The dynamic action is with :
Action : Set Value
Set Type : PL SQL funciton body
Page items to submit : P_CATEGORY (this is select list)
Escape Special Character : Yes
Suppress Change event : Yes
Affected Elements -
Selection type : Item(s)
Item(s) : P_ROOMS
This is perfectly working on Firefox but not working on IE9 & Google Chrome.
I've debugged in both IE9 & Google chrome and found the dynamic action get executes ajax call and the values get back but not rendering on the screen. i.e not assigning to the item.
So can you please advice me what will be a workaround for this issue?
I am using Application Express 4.1.0.00.32 .
I'll appreciate your prompt response.
Thanks & Regards,
Jaydipsinh Raulji

I don't understand why this is not working withouth seeing an example, there might be multiple processes working on the item.
Anyway if the value is returned check if the value is in the session aswell. If it is in the session but not on the page that means you will need to find a way to bring it from the DB to the page. You can do this by adding an action to your DA:
Action: Execute PL/SQL code
PL/SQL code: NULL;
Page Items to Return: your shuttle item

Re: Dynamic Action is not triggering in LSMW Recording

Hello All,
In SAP HRMS personnel actions if i do using LSMW Recording it is not triggering the dynamic actions.
Is there any mechanism to Trigger dynamic action in LSMW Recording ?
How to find the differences in process with and with out recording ?
Small help is also highly appreciated.

Yes. Do one thing. First study the dynamic action. Try to understand what the dynamic action is doing. Is it creating data in other infotype or is it updating some other table. Once it is clear what the dynamic action is doing then you can try to implement the same logic in LSMW. In LSMW there is a provision to add more than one recording and this recording can be called based on some logic..

Refresh report title with dynamic action

Hi all,
I have a report that is refreshed with an dynamic action. When the refresh is performed, first the value of two hidden variables are set (P2_ID and P2_NAME) and are submitted (using a dynamic action type 'pl/sql', with code 'null;' and page items to submit: P2_ID,P2_NAME).
In the query of the report, i use :P2_ID in the where-clause. That's all working like a charm! The one thing that doen't work, is the title of the region: that's defined as 'Properties of &P2_NAME.', but the title isn't refreshed when the report gets refreshed.
Is there a solution for this? I hope I'm clear enough.

See Re: Dynamic action - Refresh
So you are right; the native Refresh action just refreshes the report content, it does not perform &ITEM. substitutions everywhere in the region.
What you could do is use a named SPAN as the title like <span id="my_title">&P2_NAME.</span> and add a TRUE action to your Dynamic Action to set the title using Execute Javascript code $s('my_title',$v('P2_NAME'));Hope this helps.

Dynamic action on text box change does not working

i have a page with following components.
a report that has and edit link.
a text box to catch the primary key from report link when it is clicked
a number of elements (text boxes, check boxes and LOVs) which are used as data entry form.
Now my design is that user enter values save them and no sooner did they save, the report depicts new
values. if user want to edit any record, they click on edit link and the data entry form elements
should now bring all those values from DB on page. i m successful to pick primary key and bring
it in a hidden text box and wrote a dynamic action on its change event that will bring values from
DB and set all page elements. but but but.........the change event doesnt work. it only work
when focus is lost from the text box...!! offcourse user wont want to click in that "hiddent" text
box and then click some where else to bring values in page data entry form......
help is humbly requested from forum or if any other solution approach is to be used easier than
one i m using, would be appreciated.
thanks in advance for reading my bore question :)

bundles of thanks for reply. i m going to elaborate.
1. My page no is 3.
2. Hidden Item name is P3_EDIT_ACTIVITY_ID
3. Data entry form, hidden item and the report are on the same page.
4. on the edit link of report, i have used following settings.
    Target: Page in this application
     Page: 3
     and i set hidden item as follows......
     Item 1   P3_EDIT_ACTIVITY_ID         Value #ACTIVITY_ID#
   well, when i click the link on report it does bring Activity_Id in the hidden box (which is not yet hidden for debugging purpose)
Next i wrote Dynamic action which fires on the change event of P3_EDIT_ACTIVITY_ID and run PL/SQL code with in it which is as follows
declare
Dept varchar(50);
begin
   select my_dept into Dept from activity_main ACTIVITY_ID = :P3_EDIT_ACTIVITY_ID;
   :P3_Dept := :Dept;          (i did use :P3_Dept := Dept also but this wont work)
insert into testdynamic (stamp) values (Dept); (I did this to check whether correct value is brought from DB, yes it works correctly, correct Dept is being inserted in stamp column)
end;
i have created another true action to check when the dynamic action is fired. its very simple alert. and the problem is, it only fires when focus is lost from the P3_EDIT_ACTIVITY_ID. i mean, when u keep changing value inside the text box, nothing happens, when u go outside, the alert is fired and so the pl/sql procedure. but the line
    :P3_Dept := :Dept;       OR      :P3_Dept := Dept;         arent working which is the actual requirement.
I m not using set value here as i have to set a lot of values on page not one. further. plz let me get rid of this lost focus thing as i want the form to be populated with correct values related to P3_EDIT_ACTIVITY_ID as the user click on any edit_link in the report.
Thanks for persistence. i hope i have provided all the details.
looking forward.

Leaving a Page fires "Page Unload" dynamic action?

Hi,
Which Dynamic Action fires when I am leaving a page.
I have a page with lot of items, I want to fire alert based on some condition when user leaving that page (suppose user clicks to say some TAB), I used *"Page Unload"* dynamic action, but somehow it's not working.
Is there any other Event I have to use?

Dynamic Action with KeyCode check for ENTER button pressed

Hi,
I want to create a dynamic action which executes if the ENTER button of field P1_NAME is pressed.
I thought about this type of DA:
Event: Key Press
Selection Type: Item(s)
Item(s): P1_NAME
Condition: Javascript expression
Value: this.triggeringElement.keyCode == 13
That unfortunately doesn't work! Dynamic action doesn't get executed...
Hope for help! :)
Tobias

I found the solution in my own blog: :)
Event: Key Press
Selection Type: Item(s)
Item(s): P1_NAME
Condition: Javascript expression
Value: this.browserEvent.keyCode == 13

Dynamic action with interactive report region refresh

Hi!
I'm using APEX 4.02
I've got a page with 2 regions.
Region1 is a (input) form
Region2 is an interactive report on the same table as region 1
When entering values on the form I'm trying to dynmically lookup similar records in the table with the interactive report.
I've made a dynamic action on the change of the form fields which should refresh the interactive report region. I can see this one fires if I add a alert to debug if it fires.
The dynamic report is based on a query with bind variables pointing to the form fields, for example
where
field1 = :P2_FIELD1
This works great on the page load, so no dynamic action is fired but I can see the rows in the report region are the ones I am looking for.
But the refresh of the report region is not working, it is never refreshing and/or showing the correct data after a change of the form fields, so it looks like the dynamic action "refresh region" is not working on the interactive report.
Any ideas why this can go wrong ?
I would like to solve this using standard dynamic actions and preferrably not via PL/SQL or JS, shoudl be possible if I should believe the documentation... ;)
Cheers
Bas

Hi,
When you change value to item, I assume you do not set value to session state.
Use interactive report advanced attributes "Page Items to Submit" , set items session state before report is refreshed.

Dynamic Action with field DIVGV not working

We have built the dynamic action below to default values from infotypes 0007 and 0008 behind the screnes in infotype 0491 Payroll Outsourcing. The issue that we are having is that the dynamic action will not work for field P0008-DIVGV, but will work with all the other fields.
The only difference between the DIVGV field and the rest of the other fields mentioned in this dynamic ation is that it seems to be a free text field (which you can modify), even though the values are pulled from the work schedule rule in infotype 0007. We have also hidden the DIVGV field in 0007 per client requirement.
Does anyone have any suggestions on how to get this working. Do we need to populate these values in any of thh HR tables first?

Hi Damas,
it seems to be no specific reason for not updation P0008-DIVGV only.Please cross check whether field is populating or not in Infotype 0008, before dynamic action triggered, other that that there is no reason.

Dynamic action with function works, doesnt refresh textfield

Hi all,
experimenting with dynamic actions so I got the following setup:
I've built a screen with 2 text boxes
P7_input
P7_output
The goal is to put some tet in P7 input and have it returned with additional text in P7_OUTPUT
CREATE OR REPLACE PROCEDURE PRC_ECHO
P_INPUT IN VARCHAR2 DEFAULT 'LEEG'
, P_OUTPUT OUT VARCHAR2
) AS
BEGIN
p_output := 'Ingevoerd: ' || p_input;
END PRC_ECHO;I've created a dynamic action on the LOSE FOCUS event of item P7_INPUT.
The true action executes PL/SQL (sequence number 10)
Begin
eigen_apps.uga_prc_echo (:p7_input, :P7_OUTPUT);
end;"Page items to submit" are set to P7_INPUT, P7_OUTPUT
(and I tried with just P7_INPUT).
The second true action (sequence number 20) does a REFRESH on ITEM P7_OUTPUT (and I tried refresh region and other things I thought would make it work.)
When I enter something in P7_INPUT and tab, click or enter away from the P7_INPUT field, nothing changes in my P7_OUTPUT textfield.
Only when I hit the refresh button in my browser P7_OUTPUT is filled with 'Ingevoerd: <P7_INPUT value>.
So. The procedure does return the value into P7_OUTPUT, but I cant get an instant refresh of the P7_OUTPUT to work.
Can any of you help me?

Dynamic action with set value on date field

Hi,
I'm using APEX 4.02
I'm trying to calculate the age based on the date of birth dynamically on a form. I'm trying to do this with a (advanced)dynamic action with set value.
I'm able to get this kind of action working based on a number field etc, but NEVER on a date field.
I've read all posts on this subject but so far no solution. Even if I try to simply copy the value over to another date field or typecast it to a string ( to_char function ) it does not work. So for me the problem seems to be in the source field being a date field.
I've tried using the source value as is in a select statement :
select :P33_GEBOORTEDATUM from dual;
and also type casted based on the date format :
select TO_DATE(:P33_GEBOORTEDATUM,'DD-MON-YYYY') from dual
but still no luck.
On the same form I don't have any issues as long as the calculation is based on number fields, but as soon as I start using dates all goes wrong.
Any suggestions would be greatly appreciated. If you need any extra info just let me know.
Cheers
Bas
b.t.w My application default date format is DD-MON-YYYY, maybe this has something to do with the issue .... ?

Performance issues with dynamic action (PL/SQL)

Hi!
I'm having perfomance issues with a dynamic action that is triggered on a button click.
I have 5 drop down lists to select columns which the users want to filter, 5 drop down lists to select an operation and 5 boxes to input values.
After that, there is a filter button that just submits the page based on the selected filters.
This part works fine, the data is filtered almost instantaneously.
After this, I have 3 column selectors and 3 boxes where users put values they wish to update the filtered rows to,
There is an update button that calls the dynamic action (procedure that is written below).
It should be straight out, the only performance issue could be the decode section, because I need to cover cases when user wants to set a value to null (@) and when he doesn't want update 3 columns, but less (he leaves '').
Hence P99_X_UC1 || ' = decode(' || P99_X_UV1 ||','''','|| P99_X_UC1 ||',''@'',null,'|| P99_X_UV1 ||')
However when I finally click the update button, my browser freezes and nothing happens on the table.
Can anyone help me solve this and improve the speed of the update?
Regards,
Ivan
P.S. The code for the procedure is below:
create or replace

END;

Hi Ivan,
I do not think that the decode is performance relevant. Maybe the update hangs because some other transaction has uncommitted changes to one of the affected rows or the where clause is not selective enough and needs to update a huge amount of records.
Besides that - and I might be wrong, because I only know some part of your app - the code here looks like you have a huge sql injection vulnerability here. Maybe you should consider re-writing your logic in static sql. If that is not possible, you should make sure that the user input only contains allowed values, e.g. by white-listing P99_X_On (i.e. make sure they only contain known values like '=', '<', ...), and by using dbms_assert.enquote_name/enquote_literal on the other P99_X_nnn parameters.

Problem setting a hidden item value when button clicked with dynamic action or pl/sql process

Apex 4.1
Oracle 11g
I have a page that consists of a main region and several sub regions. I have a pl/sql process in After Header SET_DISPLAY(:P400_DISPLAY :='MAIN';)
Three subregions have a contional display where P400_DISPLAY = STORE. This works in hiding the sub regions.
Now I want to change the P400_DISPLAY value to STORE to show the subregions when I hit a button.
I tried creating a dynamic action for on click of the add button but get the following error:
The selected button uses a 'Button Template' that does not contain the #BUTTON_ID# substitution string
I went to the templates and found:
Substitution Strings
Substitution strings are used within sub templates to reference component values. This report details substitution string usage for this template.
Substitution String

#BUTTON_ATTRIBUTES#

#BUTTON_ID#

Generated button ID will be either the button's Static ID if defined, or if not will be an internally generated ID in the format 'B' || [Internal Button ID]
I then tried creating a page process, pl/sql, :P400_DISPLAY :='STORE'; when the appropriate button is pressed. The button action is submit page. However, it does not change the P400_DISPLAY value and the subregions stay hidden.
Suggestions please on how to fix the template or change the P400_DISPLAY value?

The root issue is that, although you change the value of your page item, it isn't visible to other areas of the page until it is in the session. So, any other action based on the value of your page item; the visibility of a control, a report based on the item's value, etc. will all be unaffected by changing the value of the page item until it has been changed in the session. Even after this the items are stored in the session, you must thereafter do something to cause the value to be reevaluated. To see the effect of this, observe that your page loads and evaluates the value of your page item, it sees that is "MAIN" and hides the regions. However, it doesn't reevaluate them after this.
So; your choices to get this value set in the session are to either Submit the page, or use JavaScript to set the value in the session. If you use the latter of these, you'll have to do some further work to cause the visibility tests to be re-run, So, let's stick with with the submit method.
What you've done above sounds correct for this but, there are a lot of decisions you could have made that might have caused things not to happen in the correct sequence.
Firstly, let's confirm that what I describe above is your problem. From the development environment, load the page, click the button to change the value and submit. Now, click the link labelled Session. Is it still set to MAIN? If so; this is your issue.
Let's start with the your After Header computation. Did you set it to *only* run if the current value of your page item is NULL??? If not, that's your problem.
Load Page -> Item set to 'Main' by Computation -> Click Button -> Item set to STORE -> Submit -> Load Page -> Item set to 'Main' by Computation
See the problem?
Assuming this isn't the issue, you created a Branch to the same page, right? What is your process point for the Branch? Is it *After* Validation, Computation etc? Because if not, you aren't changing the value before the submit happens.
I bet it is the first issue but, take a look at these.
Cheers,
-Joe

How to clear grey loading screen and animated gif (Dynamic Action with "Show Processing" on submit)

APEX V4.2.3
DB 11.2
I have a classic report on page 1. I have a region button called "Export" (defined by a submit dynamic action with "show processing=Yes") that submits the page and then via a branch directs me to page 2 which has a slightly different version of the report on page 1 (i.e. no breaks) which I want to capture as a CSV export. Therefore I've set the report template on page 2 to " Export:CSV".
Now when I click on the page 1 export button the grey screen and loading gif appears indicating that the report is executing and then as expected, page 2 doesn't appear but instead the standard open/save window's dialog box appears asking to open or save the generated CSV file. All good..but the grey loading screen remains. How do I clear this loading screen and get back to the context of page 1 ?
thanks in advance

We would love to help but you left out one crucial part of the puzzle: namely how does your CSV report get exported. With the way it is setup (a redirect to another page), I'm going to assume you do that because you have some PL/SQL on that page that prints the CSV.
Now there are two questions that are crucial here:
- How do we stop the icon from bugging us on the screen
- How do we communicate with the browser that it should no longer display the loading icon
The first question is rather easy, two simply lines of codes can do that:
$('#apex_wait_popup').hide();
$('#apex_wait_overlay').hide();
But when do we use this code? Quite simple when the document is downloaded. When is it downloaded? At the end of the PL/SQL code that prints the document to the browser.
What you could do is at the end of that code give an application item a certain value. For example :AI_PRINTED := 'Y';
Then all you need to do is let the browser ask for the value. You could do this by using JavaScript to continuously fire AJAX to the server using a JS timing event:

Better would be a Server send event, but since you left out another crucial piece of information: your browser, I will not go deeper into this.
Start this timing event when someone asks for the document, and end it as soon as the process returns that :AI_PRINTED equals 'Y'.
Despite the lack of information, I hope I have given, or at least inspired you to get to the solution.
Regards,
Joni
