Pl/sql package for use with workflow will not return a value

hi all,
just trying to intercept a requisition being turned into an order if it uses a certain cost code. so i have amended the workflow and created a package to check what cost centre a requisition is using. how over the workflow stops on the function that calls the package witha a status of complete as if the package is not returning any values.
the package is as below:
procedure XXHCC_CHECK_CAPITAL(itemtype in varchar2,
itemkey in varchar2,
actid in number,
funcmode in varchar2,
resultout out NOCOPY vARCHAR2);
END xxhccWFcapitalcheck;
procedure XXHCC_CHECK_CAPITAL(itemtype in varchar2,
itemkey in varchar2,
actid in number,
funcmode in varchar2,
resultout out NOCOPY varchar2 ) is
x_progress varchar2(100);
x_resultout varchar2(30);
l_doc_mgr_return_val VARCHAR2(1);
l_doc_string varchar2(200);
l_preparer_user_name varchar2(100);
doc_manager_exception exception;
p_test varchar2(100);
l_req_id varchar2(30);
CURSOR p_line_id IS
codes.segment2 cost_center
po_requisition_headers_all headers,
po_requisition_lines_all lines,
po_req_distributions_all dist,
gl_code_combinations_v codes
headers.requisition_header_id = lines.requisition_header_id
lines.requisition_line_id = dist.requisition_line_id
dist.code_combination_id = codes.code_combination_id
headers.segment1 = l_req_id;
line_rec p_line_id%rowtype;
-- Do nothing in cancel or timeout mode
--if (funcmode <> wf_engine.eng_run) then
-- resultout := wf_engine.eng_null;
-- return;
-- end if;
l_req_id := wf_engine.GetItemAttrNumber (itemtype => itemtype,
itemkey => itemkey,
aname => 'DOCUMENT_NUMBER');
--FOR line_rec in p_line_id
open p_line_id;
fetch p_line_id into l_doc_string;
close p_line_id;
IF p_line_id= 'Q9DEF'
dbms_output.put_line p_line_id;
Then resultout := 'COMPLETE:F';
resultout := 'COMPLETE:T';
END xxhccWFcapitalcheck;
any help would be great!

Hi Community,  first of all, english is not my native language and im not sure to use the correct terms for PowerCenter - so if im wrong please help me correct and make clear what we need. We have a kind of 3-steps ToDo. First step: Load data from an external source into a "local" datastore (its an oracle db on a server in our "hands")Second step: Check data against several verifications, this is done with a PL/SQL Package. The PL/SQL Package shall be called with an Interfacename who is set in the First PowerCenter Mapping. Our current thoghts are to do this via a stored procedure, which runs as "Target Post Load" and gets a variable "Interface Name".Is that possible? Im not quite sure about it. About the last part its even more unclear how we can solve it:Third part should be switch back to PowerCenter now - and the package (or to be correct a function in the package) should return a value for "okay everything fine => workflow continue" or "something happened => workflow is stopped" Im not sure how i can handle this. I hope my explanations are good enough so you can provide some help?!If there are any questions please ask!  Thank you alot, best regards, Christian

  • Using SQL Query for page item source does not insert populated value

    Hi All,
    Following are the attribute details of a certain page item on an edit form:

    Although the field appears populated on the screen, but the value is not inserted in the table.
    Can anyone help on this?
    Thanks in advance,

    One solution is to define a pl/sql function that given a date will return the 'run-date'. Something like create or replace function get_prod_date(p_date in date) return date is
    retval date;
    select run_date into retval from tab_x where run_date=p_date;

  • This driver is locked for use with embedded applications - SQL Server

    Hello guys,
    I developed an application using JSC2 with MS SQL Server 2000 as the database and Sun Application Server PE 8 as App Server. During development, I am able to deploy and test it. But as soon as I've installed Sun Application Server PE 8 on our Production Server, exported my app there and tried to execute it, I get the error
    "This driver is locked for use with embedded applications".
    I just wanna ask, though I've seen other threads saying that the only solution is to buy the EE or SE of Sun App Server, isn't there really any work-around with this?
    Thanks very much for your help.

    OK, that is the same setup we have (Creator built application running with MS SQL Server).
    I wrote a tutorial talking about integrating Creator with Spring. In it you will find out how to use SQL Server with a Creator built app running on the Platform Edition. That tutorial can be found here:
    In short, look to jTds.
    Hope this helps.

  • Will the iPhone 5c be abel for use with a Norvegian operator if I buy the phone in the US?

    Will the iPhone 5c be abel for use with a Norvegian operator if I buy the phone in the US? Im going on a vacation to USA in a few days, and i dont know when the phone will come to norway, so if it's possible, i would like to buy it in the US! Is it then possible for me to use it in Norway when i get back with a Norvegian operator?

    Jules Francis,
    The model numbers are different and each is carrier locked to their respective carriers.
    Even if they were not, the £269 price in the UK includes VAT. The price without VAT is £228.94
    The price in the U.S. Store does not include sales tax. Last time I checked sales tax in New York City is 8.375%.
    If you compare the pre-tax prices the difference is approximately £24. The rest of the difference is taxes.
    Hope this helps,

  • Adobe Acrobat package built with CCP will not completely install

    Adobe Acrobat package built with CCP will not completely install.  It starts out fine as if it is installing then suddenly disappears with no errors.   I am installing it under the local administrator account and simply double clicking on the setup.exe created in the build folder.  Am I missing something??

    Hi rivera2u & TRU Software,
    I believe you are just double clicking on the Exception Deployer and not running the same from the command prompt . Mentioned below is the syntax that we need to use while using Exception Deployer on your machine(s).
        --INSTALLDIR=<path_of_installation directory>
        --installLanguage=<locale_code for Acrobat>
    The same is mentioned in the link shared by Abhijit earlier.
    Please do let us know if this works for you or not.

  • Best drum loops for use with Logic? Ease of use, usability, etc.

    I have BFD2 but find it slow to load and sometimes clumsy auditioning loops within Logic. I love the Apple Loops library but I wondered if people are importing MIDI drum files for use with Logic. Do all drum files use the same MIDI mapping? If I drop a BFD2 loop into a Logic drum virtual instrument will it work? I bought a few packs from Groove Monkee but have yet to use them with Logic. I only use them within BFD2.
    I'm basically looking for a seamless way to stay within Logic to improve my workflow. It's taken me days sometimes to get a drum track right by going back and forth with BFD2. Is there a concept I'm missing that would make it easier?

  • How can a type defined in a PL/SQL package be used by an object?

    How can a type defined in a PL/SQL package be used by an object?
    In the PL/SQL Reference manual it says that object attributes can be
    types defined inside a PL/SQL package: How do you make this work?
    Here is a sample that demonstrates what I am trying to do:
    PACKAGE Phone IS
    TYPE Phone_rectype IS RECORD (
    Main VARCHAR2(12),
    Home VARCHAR2(12),
    Business VARCHAR2(12),
    Mobile VARCHAR2(12),
    Fax VARCHAR2(12),
    Pager VARCHAR2(12)
    END Phone;
    TYPE customer_type
    CustNo NUMBER,
    CustName VARCHAR2(30),
    PhoneNumber Phone.Phone_rectype
    This is the error that i get:
    Warning: Type created with compilation errors.
    Errors for TYPE CUSTOMER_TYPE:
    0/0 PL/SQL: Compilation unit analysis terminated
    5/15 PLS-00201: identifier 'PHONE.PHONE_RECTYPE' must be declared

    That's a good point, Justin - thanks for the advice. At the moment, our process of data validation isn't very well defined, so the table definitions aren't always the same beyond a core set. As we get more automated and able to develop table definitions flexible enough to accomodate all the quirks in client data, I may be able to consider moving to a single schema to take advantage of maintenance and performance improvements. My ultimate concern with doing that is that the datasets we're dealing with can be tens of millions of rows in size. Clearly, I'm no DBA, but I just assumed that we would be able to churn through these datasets faster if they were in a schema by themselves rather than lumped together into one huge half-a-billion row table?

  • [Oracle JDBC Driver]This driver is locked for use with embedded application

    I installed Sun Java Studio Enterprise 8, and am trying to connect to my Oracle database using the attached tutorial code.
    The code compiles fine, but I get the following error whenever I run the file: [Oracle JDBC Driver]This driver is locked for use with embedded application
    I don't understand what is happening.
    Using the Runtime navigation panel on the upper left of the IDE screen, I can right-click and connect to the database, and navigate database files, using the Oracle JDBC Driver that came with JSE8.
    Name: Oracle Driver
    Database URL: jdbc:sun:oracle://JAZZPUP:1521;SID=REPO
    If the driver is installed, and can be used to connect to a database by right-clicking on the database definition in the Runtime panel, why can't I connect to it just using java code in the IDE. I would expect both methods to work or to fail, not one of each using the same IDE.
    Many thanks and take care,
    import java.sql.*;
    public class CreateCoffees {
    public static void main(String args[]) {

    There are two similar threads:
    To summarize - the DataDirectDriver that is shipped with the IDE seems to be locked to be used inside the IDE only because of some licensing issues etc..
    That's weird, I agree. I will raise a question on reasons for such a behavior.
    The solution would be to use Oracle's own driver, that is distributed at no charge from their web site -

  • Does an upgrade to ilife 11 contain idvd for use with mountain lion (10.8.5)?

    Does an upgrade to ilife 11 contain iDVD for use with mountain lion (10.8.5)?  I received an advertisement about upgrading to iLife 11 and it discusses sharing via iDVD, which was disabled when I upgraded to Mountain Lion OS 10.8.5.  Would purchasing the iLife 11 download restore the functionality of iDVD, or is this just another way to get the sheep to upgrade iMovie with no way to export to iDVD or equivalent.  Why is there no Apple warning that Mountain Lion disables and does not support iDVD?  I used to think Microsoft was a trickster, but I'm of the opinion that Apple meets or exceeds their slippery machinations.  Am I just stuck with purchasing a 3rd party software to replace iDVD?

    If iDVD was not preinstalled on your Mac you'll have to obtain it by purchasing a copy of the iLife 09 disk from a 3rd party retailier like ilife 09: Software or  Why, because iDVD (and iWeb) was discontinued by Apple over a year ago. 
    Why iLife 09 instead of 11?
    If you have to purchase an iLife disc in order to obtain the iDVD application remember that the iLife 11 disc only provides  themes from iDVD 5-7.  The Software Update no longer installs the earlier themes when starting from the iLIfe 11 disk nor do any of the iDVD 7 updaters available from the Apple Downloads website contain them. 
    Currently the only sure fire way to get all themes is to start with the iLife 09 disc:
    This shows the iDVD contents in the iLife 09 disc via Pacifist:
    You then can upgrade from iDVD 7.0.3 to iDVD 7.1.2 via the updaters at the Apple Downloads webpage.
    Export the slideshow out of iPhoto as a QT movie file via the Export button in the lower toolbar.  Select Size = Medium or Large.
    Open iDVD, select a theme and drag the exported QT movie file into the open iDVD window being careful to avoid any drop zones.
    Follow this workflow to help assure the best qualty video DVD:
    Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image  menu option. This will separate the encoding process from the burn process. 
    To check the encoding mount the disk image, launch DVD Player and play it.  If it plays OK with DVD Player the encoding is good.
    Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality.  Always use top quality media:  Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

    You can't write to it because it's formatted as NTFS which OS X will read but not write to. If you want to continue using the drive with both a PC and OS X you will need to download and install NTFS-3G so you can then write to it from your Mac. You can get NTFS-3G at:
    If you want to use the drive exclusively with your Mac then move the data off it and reformat it in Disk Utility (Applications - Utilities - Disk Utilities) as Mac OS Extended (Journaled.)
