Best approach for select lists to hold more than 3000 values urgent plz

Hello,
I have an interactive report in which I have made one of the column as a editable dropdown list item using the APEX API ITEM APEX_ITEM.SELECT_LIST_FROM_QUERY_XL, I am getting an error saying that
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
I think the drop down list is not able to hold that many values. The number of values can grow in the future.
Can anyone suggest me any other approach to resolve this issue.
Thanks,
Orton

thanks for your reply.
Yes I have tried but the popup lov is not returning a value to my report when i click a value on the POPUP lov.
So I did it in another way, the same problem exists again its not returning the value.
Like I have a interactive report, in which I have have made one of column as an editale text item and concatenated it with an image when clicked on the image
opens up an popup report (interactive report)
Source query of the Report
select
apex_item.hidden(04,CHF_TABLE_KEY,' ','f04_' || ROWNUM)
|| APEX_ITEM.HIDDEN(01,ROWNUM,'','f01_' || ROWNUM) " ",
APEX_ITEM.TEXT (25,CHF_SOURCE_TABLE,30,NULL,'f25_' || ROWNUM)
|| ' '||'<img height="18" align="middle" width="18" style=""
alt="Source Table Popup" src="/i/lov_16x16.gif"
onclick="javascript:popUp2(''f?p=&APP_ID.:50''||ROWNUM);" />' SOURCE_TABLE_EDIT,
CHF_SOURCE_DATASTORE,
CHF_SOURCE_SCHEMA,
CHF_SOURCE_TABLE
FROM CHF_TABLE_SOURCE
ORDER BY CHF_SOURCE_TABLE
My popup is an interactive report (Region source: select distinct chf_table from chf_table order by 1) which contains only one column which is a link column
whose link Text: #CHF_TABLE#
Target: URL
URL: javascript:CallReport('#CHF_TABLE#');
P50_PITEM is the hidden item.
Javascript for the popup page HTML Header is
<script type="text/javascript">

</script>
My problem is, like when I click the image a popup report window appears but I am not able to return the value when I clicked the link column on the popup report page.
Can you please help me out with this issue.
thanks,
Orton

Set parameter id for select-options to fill more than one value

FROM MY CUSTOM PROGRAM I AM CALLING A TRANSACTION CODE. IN MY REPORT I WANT TO SELECT MORE THAN ONE RECORD AND TO CALL THE TRANSACTION BY PASSING THE SELECTED VALUES TO THE SELECT-OPTIONS OF THE TRANSACTION.
IF IT IS A PARAMETER I CAN WRITE SET PARAMETER STATEMENT FOR ONE VALUE AND EASILY CALL THE TRANSACTION. BUT I WANT TO FILL THE SELECT-OPTIONS OF THE TCODE.
CAN ANYBODY PLEASE PROVIDE ME THE LOGIC HOW TO FILL THE SELECT-OPTIONS FROM MY REPORT FOR CALLING THE TRANSACTION.
REGARDS,
VASU.

Hi..
Instead of calling the Transaction
Call the Report directly using:
(First declare the Ranges)
ranges : R_matnr for mara-matnr.
(Fill the values into Ranges Table and call the report )
SUBMIT <REPORT>
With s_matnr in R_matnr.

Best approach -To create RTF template having more than 50 tables.

Hi All,
Need your help.I am new to BI publisher. Currently we are using BIP 11g.
I want to develop.rtf template having lots of layout and images.
Data is coming from different tables (example : pulling from around 40 tables). When i tried to pull data from 5 tables by joining tables. It takes more time using data model in BI publisher 11g saved in xml and used in word doc.
Could you please suggest best approach weather i need to develop .rtf template via data model or query to generate a report.
Also please suggest / guide me .
Regards & Thanks in advance.

it's very specific requirements
first of all it's relate to logic behind
as example 50 tables are related ? or 50 independent tables ? or may be 5 related and another independent ?
based on relation of tables you create sql statement(s)
how many sql statement(s) you'll have lead to identify ways to get data, as example, by package or trigger etc
kim size of resulting select statement(s)
if size say 1mb it's must be fast to get report but for 1000mb it can consume many time
also kim what time it's not only to select data but to merge data and template
looks like experimenting and knowing full logic of report is only ways to get needed output in projection of data and time

What are the best approaches for mapping re-start in OWB?

What are the best approaches for mapping re-start in OWB?
We are using OWB repository 10.2.0.1.0 and OWB client 10.2.0.1.31. The Oracle version is 10 G (10.2.0.3.0). OWB is installed on Linux.
We have number of mappings. We built process flows for mappings as well.
I like to know, what are the best approches to incorportate re-start options in our process. ie a failure of mapping in process flow.
How do we re-cycle failed rows?
Are there any builtin features/best approaches in OWB to implement the above?
Does runtime audit tables help us to build re-start process?
If not, do we need to maintain our own tables (custom) to maintain such data?
How did our forum members handled above situations?
Any idea ?
Thanks in advance.
RI

Hi RI,
How many mappings (range) do you have in a process flows?Several hundreds (100-300 mappings).
If we have three mappings (eg m1, m2, m3) in process flow. What will happen if m2 fails?Suppose mappings connected sequentially (m1 -> m2 -> m3). When m2 fails then processflow is suspended (transition to m3 will not be performed). You should obviate cause of error (modify mapping and redeploy, correct data, etc) and then repeat m2 mapping execution from Workflow monitor - open diagram with processflow, select mapping m2 and click button Expedite, choose option Repeat.
In re-start, will it run m1 again and m2 son on, or will it re-start at row1 of m2?You can specify restart point. "at row1 of m2" - I don't understand what you mean (all mappings run in Set based mode, so in case of error all table updates will rollback,
but there are several exception - for example multiple target tables in mapping without corelated commit, or error in post-mapping - you must carefully analyze results of error).
What will happen if m3 fails?Process is suspended and you can restart execution from m3.
By having without failover and with max.number of errors=0, you achieve re-cycle failed rows to zero (0).This settings guarantee existence only two return result of mapping - SUCCSES or ERROR.
What is the impact, if we have large volume of data?In my opinion for large volume Set based mode is the prefered processing mode of data processing.
With this mode you have full range enterprise features of Oracle database - parallel query, parallel DML, nologging, etc.

Best approach for RFC call from Adapter module

What is the best approach for making a RFC call from a <b>reciever</b> file adapter module?
1. JCo
2. Is it possible to make use of MappingLookupAPI classes to achieve this or those run in the mapping runtime environment only?
3. Any other way?
Has anybody ever tried this? Any pointers????
Regards,
Amol

Hi ,
The JCo lookup is internally the same as the Jco call. the only difference being you are not hardcoding the system related data in the code. So its easier to maintain during transportation.
Also the JCO lookup code is more readable.

Best Approach for Reporting on SAP HANA Views

Hi,
Kindly provide information w.r.t the best approach for the reporting on HANA views for the architecture displayed below:
We are on a lookout for information mainly around the following points:
There are two reporting options which are known to us and listed below namely:
Reporting on HANA views through SAP BW (View > VirtualProvider > BEx > BI 4.1)
Reporting on HANA views in ECC using BI 4.1 tools
Which is the best option for reporting (please provide supportive reasons : as in advantages and limitations)?
In case a better approach exists, please let us know of the same.
Best approach for reporting option on a mixed scenario wherein data of BW and HANA views is to be utilized together.

Hi Alston,
To be honest I did not understand the architecture that you have figured out in your message.
Do you have HANA instance as far as I understood and one ERP and BW is running on HANA. Or there might be 2 HANA instance and ERP and BW are running independently.
Anyway If you have HANA you have many options to present data by using analytic views. Also you have BW on HANA as EDW. So for both you can use BO and Lumira as well for presenting data.

What's Best Approach for Multitrack Classical Music?

Can someone suggest the best approach for recording classical musicians onto
four tracks? In this scenario, they play until they make a mistake on, say,
measure 24, stop, then (take 2) go back to measure 20 and play until the next
rough spot, and so on. Ultimately there may be 15 takes that all need to be
trimmed and stitched together.
In the old (tape) days, this was pretty basic editing. I would use a blade and block
to cut out all the bad stuff on the multitrack tape, then I could mix. But how do I
do this in Audition? (I use version 1.5.)
I can't do the cuts it in edit view because the tracks would get out of sync
Assuming all the takes are in one session, in multitrack view, this most basic of
functions seems to elude me. What am I missing?

If you follow Steve's advice, and after doing the edits you discover

I could be wrong about this in the classical music environment,
where things are not close-mic'ed but if I am, I am confident Steve
will correct me. Ha.
You always run the risk of small changes between takes - and that's where Audition 3 and the new improved crossfades score rather heavily. You won't notice 1dB on a single instrument across a fade though - it's hard to spot this as a jump, even, unless it's on pure tone. No, I very rarely close-mic stuff at all, although I did with a clavichord recently - it's seriously too quiet to mic any other way.

That's the way they used to work, certainly - but not nowadays, especially if it's done on location, which most classical recording is. What's more likely to happen is that you'd use decent mic preamps feeding straight into a multitrack, or even some software on a laptop. I generally record like that - but I also feed the multitrack outputs to a Yamaha mixer via ADAT, do a mix on that and record it back to a spare multitrack pair. I don't actually need to do that - but having a mix available from the multitrack that's pretty much there is good as far as being able to play back takes to conductors is concerned.
Of course, one of the other reasons that classical sessions recorded on location aren't mixed on the spot is that the monitoring conditions are invariably far from ideal, and I'd have it that no engineer worth anything would ever risk a final mix done on location.
But I only get paid to do all of this on a regular basis, so what would I know? Must be something though - my customers come back for more...

Best approach for uploading document using custom web part-Client OM or REST API

Hi,
Am using my custom upload Visual web part for uploading documents in my document library with a lot of metadata.
This columns contain single line of text, dropdownlist, lookup columns and managed metadata columns[taxonomy] also.
so, would like to know which is the best approach for uploading.
curretnly I am trying to use the traditional SSOM, server oject model.Would like to know which is the best approach for uploading files into doclibs.
I am having hundreds of sub sites with 30+ doc libs within those sub sites. Currently its taking few minutes to upload the files in my dev env. am just wondering, what would happen if the no of subsites reaches hundred!
am looking from the performance perspective.
my thought process is :
1) Implement Client OM
2) REST API
Has anyone tried these approaches before, and which approach provides better performance.
if anyone has sample source code or links, pls provide the same
and if there any restrictions on the size of the file uploaded?
any suggestions are appreciated!

Browsers and versions? (Always supply this information when discussing presentation and UI problem.)
If it's IE, then this is not possible (at least up until IE7 which is all I can test on at present).
(As HTML, CSS and JavaScript exist outside of APEX, you should search more widely than just OTN when looking for information on these topics.)

1.Using separate schema s for various type users(We can store only relevant data with a particular schema. Then No. of records per table can be reduced by replicating tables but we have to maintain all data with a another schema Then we need update two schema s for a given session.Because we maintain separate scheama for a one user and another schema for all data and then there may be Updating problems)
OR
2. Using single schema for all users.
Note: All users may access the same tables and there may be lot of records than previous case.

Best approach for IDOC - JDBC scenario

Hi,
In my scenarion I am creating sales order(ORDERS04) in R/3 system and which need to be replicated in a SQL Server system. I am sending the order to XI as an IDoc and want to use JDBC for sending data to SQL Server. I need to insert data in two tables(header & details). Is it possible without BPM? Or what is the best approach for this?
Thanks,
Sri.

Yes, this is possible without the BPM.
Just create the Corresponding Datatype for the insertion.
if the records to be inserted are different, then there wil be 2 different datatypes ( one for header and one for detail).
Do a mutlimapping, where your Source is mapped into the header and details datatype and then send using the JDBC sender adapter.
For the strucutre of your Datatype for insertion , just check this link,
http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/content.htm
To access any Database from XI, you will have to install the corresponding Driver on your XI server.

DA for Select List is not working

Hi friends,
I have a two fields in my form.
<li>person id
<li>Manager Name(Select List)
I have given a default value for person id as'270'. So i need to write an dynamic action so that it will fetch the manager name according to the person id '270'.
Since My manager Name is an Select List type, i have given the following query in the LOV definition of this item
select papf.full_name d, papf.person_id r
from per_all_people_f papf,
     per_all_assignments_f paaf,
     per_all_people_f supf, hr_all_positions_f hapf, hr_all_organization_units haou
where papf.business_group_id = 216
and papf.person_id = paaf.person_id and hapf.position_id=paaf.position_id and haou.organization_id=paaf.organization_id
and NVL(paaf.supervisor_id, papf.person_id) = supf.person_id
and sysdate between papf.effective_start_date and papf.effective_end_date
and sysdate between paaf.effective_start_date and paaf.effective_end_date
and sysdate between supf.effective_start_date and supf.effective_end_date
and sysdate between hapf.effective_start_date and hapf.effective_end_date
and papf.person_type_id = 5145
order by 1   This is the DA, that i wrote for the person id column.
For the true action, i have given as 'Set Value' and given the following query
select supf.full_name
from per_all_people_f papf,
     per_all_assignments_f paaf,
     per_all_people_f supf, hr_all_positions_f hapf, hr_all_organization_units haou
where papf.business_group_id = 216
and papf.person_id = paaf.person_id and hapf.position_id=paaf.position_id and haou.organization_id=paaf.organization_id
and NVL(paaf.supervisor_id, papf.person_id) = supf.person_id
and sysdate between papf.effective_start_date and papf.effective_end_date
and sysdate between paaf.effective_start_date and paaf.effective_end_date
and sysdate between supf.effective_start_date and supf.effective_end_date
and sysdate between hapf.effective_start_date and hapf.effective_end_date
and papf.person_type_id = 5145 and papf.person_id = :P6_PERSON_IDPage item to submit: P6_PERSON_ID
Affected Element: P6_MANAGER_NAME.
Soon after the page load, the manger field has to show the corresponding manager name in the LOV according to the value '270' which is in the person id item. But it is not showing the corresponding name in the select list item.
Suppose, if the manager name item is in 'display only' means it is working, but if the manager name field is in LOV means it is not fetching the value and it is displaying only the null display value in that field.
I dont know why the DA is not working if the field is in LOV.

Hi Patrick,
Thanks, and this is the mistake that i made and it worked now fine.
I have Certain questions for you:
<li> Currently, i can able to send mails from APEX using APEX_MAIL, but APEX_MAIL will support only in the unauthenticated mail server. Since in our organization we have configured an unauthenticated mail server and we are using that server for the APEX mail process. The problem that im facing now is, this mail server is been used in our organization entirely for all the purpose, except the official mail.[For official mail purpose we are using Yahoo server, which is an authenticated server, and we are using that Yahoo mail server only for your official mail purpose].
For remaining all the purpose including the APEX mail process too we are using the unauthenticated mail server that we configured. Since we are make using of unauthenticated mail server for all the purpose and due to that, the mail process is getting very slow and i couldnt able to receive the mail from the APEX in time(via) this unauthenticated mail server.
So, due to that i thought of using the Yahoo mail server(which is an authenticated mail server). But APEX_MAIL doesnot support for the authenticated server, then how i can use the authenticated mail server for sending the mail via APEX. How i can able to access the Yahoo mail authenticated server from Oracle Database.(i have also enabled ACL in my DB too).
<li> Second question, is how i can able to refer the APPLICATION PROCESS in my application. Other than calling that APPLICATION PROCESS In javascript, it is possible to call that APPLICATION PROCESS in the plsql anonymous block.
Brgds,
Mini

Best approach for building dialogs based on Java Beans

I have a large amount of Java Beans with several properties each. These represent all the "data" in our system. We will now build a new GUI for the system and I intend to reuse the beans as far as possible. My idea is to automatically generate the configuration dialogs for each bean using the java.beans package.
What is the best approach for achieving this? Should I use PropertyEditors or should I make my own dialog-generator using the Introspetor class or are there any other suitable solutions?
All suggestions and tips are very welcome.
Thanks!

Definitely, it is better for you to use JTable. Why not try it?

Best approach for publishing a paid version and an ad supported free version of the same app

Hi,
One of my Windows 8 store app is almost ready for store submission.
What is the best approach for publishing a paid version and an ad supported free version of the same app.
Can I do the following
1. Submit the app with unlimited free trial to store
2. During the free trial ads will be displayed
3. If the user purchases the app, then the ad would not displayed
Any advise is greatly
appreciated.
Best Regards

Although the in-App purchase option is good but for ad based apps my approach is different.
I would suggest putting 2 different apps in the store, one free with Ads and one without. Reason being you want the extra reference and xaml ad controls depending upon how
many you have on the paid version of the apps. I would keep my apps as lighter and cleaner as possible specially when its a paid app.
I currently manage both free and paid app through one solution and reuse most of the code except for the views.
