Executing Dynamic actions in Background???

Hello Experts,
We have a requirement where we need to automate PA40. The data would be sent in csv file and we need to perform the required steps to insert data into Infotypes.
The issue is in batch mode (background mode), the dynamic actions wouldn't be called and the business wants the dynamic actions to be considered as well.
Pls let me know if there is any way we can interpret the dynamic actions dynamically; meaning the prog should be able to handle the newly created dynamic actions as well.
Any pointers to this are highly appreciated.

Hello Raj;
In documentation of Dynamic Actions it is written so:
Note on creating a batch input session:
Dynamic actions are not processed in a batch input session.
In batch input, you must specify the exact sequence of the screens. To
ensure this is the case, you must have already programmed the dynamic
action checks before you create the batch input session.
To avoid errors only the static actions are processed when you program
and process a session. Infotypes that usually only appear in the system
as a result of a dynamic action should be updated by calling up the
transaction separately.
Hope this can help you,
Regards.

Executing dynamic action JS then plsql code with checkbox.

All,
I have a checkbox which when clicked i want to run javascript expression then next plsql code in that sequence. But iam getting the first issue here when i put in JS an expression like document.getElementById("P111_CHECK1").value ... or even document.getElementById("P111_CHECK1").checked i always get undefined error. So how can i determine if the checkbox is checked or unchecked in DA? thanks in advance.

Hi,

Execute javascript from plsql in a dynamic action.

Is it possible to execute javascript with htp.p from a plsql block in a dynamic action (on change).
I have tried it but I get a JSON error.
The reason I want to to this is:
I have to check something with plsql and depending on the result I want to do something in javascript.
I now going to try it with ajax from javascript, but if somebody has a other way to do this i like to hear it.
Thanks,
Fred.

Very neat, many thanks.
I now have a 'Set Value' 'Javascript Expression' action of 'this.triggeringElement.id;' to set a hidden *but unprotected* page item. This is followed by the 'Execute PL/SQL' action which simply calls a package procedure and passes the name of the triggering item. The procedure then sets the session state(s) as required.
Thank you!

Dynamic actions user execute the Hiring action, IT 0105 dynamically adjust

Hello Any body can guid me for the below requirement..
Whenever the user execute the Hiring action (action type: Z1-Hiring cPA) the system should adjust the infotype 0105 dynamically during executing the hiring process, in the same way the subtype (0010 : E-mail )for the userid in SAP HR should be adjusted. The HR Services should not have to do this manually.
The e-mail account can be composed from the fields first name, name prefix and birth name. The fields have to be separated by dots. When the name prefix contains more words they have to be separated by a dot.
When company code is 003 the value email atthe rate xx.comhas to be adjusted at the end.
When company code is 004 the value email atthe rate yy.com has to be adjusted at the end.

I can not execute a dynamic action if I execute a BI

I am executing an infotype in Batch input with a call transaction and the dynamic actions don't work.
Any ideas.
Thank you.

Unfortunetly dynamic actions (T588Z) are not called in batch input mode - that is standard SPA HR processing.
The normal process is to create all the infotypes in the batch input program - even the ones that would be created by dynamic actions if running online in PA30/PA40
hope that helps

The background execution works correctly for Action Types Z3 and Z7 which are not linked to Recruitment.
The execution of Dynamic Action DOESN'T WORK in the background mode but it works in foreground (even if in the dynamic action I've wrote /D) for Z1-Z2-ZC: these actions are linked to Recruitment.
Can you help me?

All the Actions are for Personnel Administration.
Actions:
Z1-Z2-ZC in T529A-FUNCH are customized like "7 Initial hiring and transfer of data from Recruitment" --> the dynamic action works but in foreground
Z3-Z7 in T529A-FUNCH are customized like "0     Other actions" or "1     Initial hiring" --> the dynamic action works correctly in the background

Hi Marie,
as Matthew says, the only part of the code that could result in that error is the select into statement. This is because, in pl/sql, a select into statement is expected to return one row only. If it returns no rows it raises a no data found exception and if it returns more than one row it raises a too many rows error.
If it is acceptable that this query may return no rows, then you have to handle this situation. The two methods that you can use would be firstly to use a named cursor and fetch a row from this, if there is no data then it does not raise an exception. The other method would be to put in an exception handler around the select statement.
EG - prefered, mainly because I think it is better to code in a way that minimises exception handling.

Help using a dynamic action to update tabular form items (specifically radio button) based on collection

Hi Everyone, I have posted this question in the past and made huge progress with Denes Kubicek's help: https://apex.oracle.com/pls/apex/f?p=31517:294:115851992029365::::: based on my earlier question posted: https://forums.oracle.com/forums/thread.jspa?threadID=2537494
I am struggling with one item in my tabular form. It is a radio button. The choices all appear properly, but the value is not saved in the collection (and hence, not saved in the table). All other items in the tabular form save properly.
here is what I have for the query.   It is item c024 (which maps to ;'f03'), which is defined as a radio LOV based on an existing LOV.
Currently I have:
2 page items:
P110_ID
P110_VALUE
Dynamic action called CHANGE COLUMN:

I have noticed the following:
when I change column C011 (price) the following values are set in the dynamic action:
P110_ID = f11_1
P110_VALUE = whatever I change the price to.
when I change the column C024 (hms_flag), the following values are set:
P110_ID = f03_0001
P110_VALUE = whatever I change hms_flag to.
the region is refreshed in my dynamic action, and the change for hms_flag does not hold. I have tested the SQL query that generates the value for v_SEQ in the dynamic action.   In both a change to price and HMS_FLAG it appears valid
select ltrim(substr(:p110_ID,5,4),'0') into v_seq from dual;
if f11_1, v_seq:= 1
if f03_0001, v_seq := 1
thank you!

solved. sort of.
field c024 references f03.
the Dynamic ACtion, step 4 calculates v_member by taking a substring of P110_ID...and in all other fields, the column and the field (fxx) are the same value....except for c024.
I am not certain exactly how to resolve, but see the problem.

Hi.
As far as i know, the limitation comes from the BDC execution itself, it doesn't really matter whether the execution is online or in batch mode.

One thing you could try to do to avoid this and get the dynamic measures executed is to use the NOBINPT variable of the OPTIONS structure in CALL TRANSACTION

CALL TRANSACTION 'PA30' USING bdcdata OPTIONS FROM opt.

Dynamic Actions with Multiple Actions Capability

Dynamic Actions with Multiple Actions Capability
How can I get Dynamic Actions to work on Actions that are stored solely on IT0302 due to the multiple relationship to a previous Action that is stored on both IT0302 and IT0000?
When multiple actions on a given day are executed, the dynamic action from the first action entered is executed twice - when it should only execute the first time with the second actions dynamic action triggering the second time.
Thanks

When there are multiple actions with the same effective date the wrong dynamic action is triggered. For example, if I have an Expat Return To Home action followed by an Internal Move action with the same effective date the below events occur:
1. IT0001 is updated due to Expat Return to Home - triggering the Dynamic Action off of IT0000 which is Expat Return to Home (Correct)
- Action is stored on IT0000 and IT0302
2. IT0001 is updated due to Internal Move - triggering the Dynamic Action off of IT0000 which is Expat Return to Home (Incorrect - background processing creates data not needed)
- Action is stored only on IT0302
Question:
How can we leverage Multiple Actions with the same effective date while continuing to use Dynamic Actions?

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

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.

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! :)

I found the solution in my own blog: :)

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?

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
PROCEDURE DWP.PROC_UPD

P99_X_UV1 in VARCHAR2,

P99_X_V2 in VARCHAR2,
P99_X_COL3 in VARCHAR2,

EXECUTE IMMEDIATE l_sql_stmt;
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.
